A Rare Case of an Eosinophilic Pleural Effusion and Loculated Ascites Associated with Strongyloides stercoralis Hyperinfection Syndrome in California.

Introduction. Strongyloides stercoralis causes a helminthic infection that occurs via penetration of the skin with migration to the bloodstream, tracheobronchial tree, and gastrointestinal system. Pulmonary manifestations are rare and are typically seen in immunosuppressed patients who have Strongyloides stercoralis hyperinfection syndrome. Eosinophilic pleural effusions are rare in strongyloidiasis and only cited in a few case reports. Case Presentation. A 45-year-old male with a past medical history of diabetes mellitus, alcoholic cirrhosis, and end-stage renal disease presented to the emergency department with abdominal pain and dyspnea. Imaging studies demonstrated large bilateral pleural effusions, and he subsequently underwent an ultrasound-guided thoracentesis on the right hemithorax, yielding an exudative eosinophilic pleural effusion. An extensive hematology, gastroenterology, and infectious work-up was pursued. Strongyloides immunoglobulin G was positive, and he was successfully treated with ivermectin. Discussion. Eosinophilic pleural effusions related to strongyloidiasis are exceedingly rare. Clinicians should consider Strongyloides stercoralis infection as a part of the differential diagnosis when evaluating immunosuppressed patients with eosinophilic pleural effusions. Loculated abdominal fluid may also be a rare manifestation of Strongyloides stercoralis hyperinfection syndrome.

Sclerosing epithelioid fibrosarcoma associated with WRN gene variant presenting as chronic dyspnea and pathologic cervical fracture: a case report and review of the literature.

BACKGROUND: Sclerosing epithelioid fibrosarcoma is an aggressive sarcoma subtype with poor prognosis and limited response to conventional chemotherapy regimens. Diagnosis can be difficult owing to its variable presentation, and cases of sclerosing epithelioid fibrosarcoma are rare. Sclerosing epithelioid fibrosarcoma typically affects middle-aged individuals, with studies inconsistently citing gender predominance. Sclerosing epithelioid fibrosarcoma typically arises from the bones and soft tissues and often has local recurrence after resection and late metastases. Immunohistochemical staining typically is positive for mucin-4. Werner syndrome is due to an autosomal recessive mutation in the WRN gene and predisposes patients to malignancy. CASE PRESENTATION: A 37-year-old Caucasian female presented to the emergency department with 4 months of dyspnea and back pain. She had been treated for pneumonia but had persistent symptoms. A chest, abdomen, and pelvis computed tomography showed near-complete right upper lobe collapse and consolidation, mediastinal lymphadenopathy, lytic spinal lesions, and a single 15-mm hypodense liver nodule. The patient underwent a transthoracic right upper lobe biopsy, bronchoscopy, endobronchial ultrasound with transbronchial lymph node sampling, and bronchoalveolar lavage of the right upper lobe. The bronchoalveolar lavage cytology was positive for malignant cells compatible with poorly differentiated non-small cell carcinoma; however, the cell block materials were insufficient to run immunostains for further investigation of the bronchoalveolar lavage results. Consequently, the patient also underwent a liver biopsy of the liver nodule, which later confirmed a diagnosis of sclerosing epithelioid fibrosarcoma. Next-generation sequencing revealed a variant of unknown significance in the WRN gene. She was subsequently started on doxorubicin. CONCLUSION: Sclerosing epithelioid fibrosarcoma is a very rare entity, only cited approximately 100 times in literature to date. Physicians should be aware of this disease entity and consider it in their differential diagnosis. Though pulmonary involvement has been described in the context of sclerosing epithelioid fibrosarcoma, this malignancy may affect many organ systems, warranting extensive investigation. Through our diagnostic workup, we suggest a possible link between sclerosing epithelioid fibrosarcoma and the WRN gene. Further study is needed to advance our understanding of sclerosing epithelioid fibrosarcoma and its clinical associations as it is an exceedingly rare diagnosis.

The impact of impaired insulin regulation on severity of SARS-CoV-2 infection: a 2-year retrospective single-center analysis.

Background: The COVID-19 pandemic has caused an international healthcare crisis and produced a large healthcare burden. Diabetes mellitus (DM) is a common disease that can be controlled via pharmacologic agents; however, many patients have poor glycemic control, leading to disease-related complications. DM has been reported in the literature to be associated with increasing morbidity and mortality in COVID-19 patients. The authors aim to assess the associations between glucose homoeostasis and COVID-19 disease severity and mortality. Methods: A retrospective chart review of patients ages 18-100 years of age admitted with COVID-19 between January 2020 and December 2021 was performed. The primary outcome was COVID-19 mortality with respect to haemoglobin A1C levels of less than 5.7%, 5.7-6.4%, and 6.5% and greater. Disease severity was determined by degree of supplemental oxygen requirements (ambient air, low-flow nasal cannula, high-flow nasal cannula, non-invasive mechanical ventilation, and invasive mechanical ventilation). COVID-19 mortality and severity were also compared to blood glucose levels on admission as grouped by less than 200 mg/dl and greater than or equal to 200 mg/dl. Results: A total of 1156 patients were included in the final analysis. There was a statistically significant association between diabetic status and mortality (P=0.0002). Statistical significance was also noted between admission blood glucose ≥200 mg/dl and mortality (P=0.0058) and respiratory disease severity (P=0.0381). A multivariate logistic regression for predicting mortality showed increasing haemoglobin A1C was associated with increased mortality (odds ratio 1.72 with 95% CI of 1.122-2.635). Conclusions: In our 2-year retrospective analysis, there was an association between a diagnosis of DM and COVID-19-related mortality. Hyperglycaemia on admission was found to be statistically significant with mortality in patients diagnosed with COVID-19. Glucose homoeostasis and insulin dysregulation likely play a contributing factor to COVID-19 disease severity and mortality.

Acute Respiratory Distress Syndrome: A Rare Manifestation of Rhinovirus Infection.

Human rhinovirus (HRV) is a common cause of respiratory infections. HRV-related lower respiratory tract infections, including community-acquired pneumonia, are seldom seen in the clinical setting, and progression to acute respiratory distress syndrome (ARDS) is even rarer. We report on a case of a young immunosuppressed host who presented to the hospital for respiratory distress. She was diagnosed with HRV-related pneumonia, which rapidly progressed to ARDS based on clinical examination. After orotracheal intubation and mechanical ventilation with a low tidal volume strategy, she made a rapid recovery. This case highlights the importance of understanding that HRV may be an etiology of community-acquired pneumonia in immunosuppressed hosts and that ARDS may be a complication of this infection. Rapid recognition and clinical suspicion are important to the care of these patients, as ARDS has a high mortality rate.

Primary Mediastinal B-Cell Lymphoma Presenting as Cardiac Tamponade.

Primary mediastinal B-cell lymphoma (PMBCL) is a rare subtype of non-Hodgkin lymphoma. Typical symptoms include cough, chest pain, and dyspnea; however, cardiac tamponade as the primary manifestation is exceedingly rare. We hereby present a case of a 34-year-old male with a past medical history of obesity, who presented to our emergency department with a chronic dry cough for 4 months. On admission, computed tomography demonstrated a large 11.1-cm diameter anterior mediastinal mass, and echocardiography demonstrated cardiac tamponade physiology. The patient underwent further workup including pericardiocentesis, subsequent pericardial window, and mediastinal biopsy, which demonstrated histopathology consistent with PMBCL. Our case highlights the importance of a complete and thorough workup for patients with chronic untraditional symptoms. This case is unique in that PMBCL is rarely associated with cardiac tamponade as the primary clinical presentation. Additionally, we recommend an extensive cardiac workup for patients presenting with a large mediastinal mass, as failure to do so may result in patient morbidity and mortality.

ABO blood group and rhesus factor association with inpatient COVID-19 mortality and severity: a two-year retrospective review.

Background: Early reports have indicated a relationship between ABO and rhesus blood group types and infection with SARS-CoV-2. We aim to examine blood group type associations with COVID-19 mortality and disease severity. Methods: This is a retrospective chart review of patients ages 18 years or older admitted to the hospital with COVID-19 between January 2020 and December 2021. The primary outcome was COVID-19 mortality with respect to ABO blood group type. The secondary outcomes were 1. Severity of COVID-19 with respect to ABO blood group type, and 2. Rhesus factor association with COVID-19 mortality and disease severity. Disease severity was defined by degree of supplemental oxygen requirements (ambient air, low-flow, high-flow, non-invasive mechanical ventilation, and invasive mechanical ventilation). Results: The blood type was collected on 596 patients with more than half (54%, N=322) being O+. The ABO blood type alone was not statistically associated with mortality (P=0.405), while the RH blood type was statistically associated with mortality (P<0.001). There was statistically significant association between combined ABO and RH blood type and mortality (P=0.014). Out of the mortality group, the O+ group had the highest mortality (52.3%), followed by A+ (22.8%). The combined ABO and RH blood type was statistically significantly associated with degree of supplemental oxygen requirements (P=0.005). The Kaplan-Meier curve demonstrated that Rh- patients had increased mortality. Conclusion: ABO blood type is not associated with COVID-19 severity and mortality. Rhesus factor status is associated with COVID-19 severity and mortality. Rhesus negative patients were associated with increased mortality risk.

Symptomatic Bronchogenic Cyst in a Lipomatous Interatrial Septum.

Intracardiac bronchogenic cysts are extremely rare congenital anomalies that arise during foregut development when the embryologic heart tube and ventral foregut are in close proximity to one another. We report a case of an interatrial septal bronchogenic cyst found on non-contrast enhanced computed tomography (CT) in a 66-year-old female who presented to the emergency department with chest pain. Further cardiac investigations, including contrast-enhanced CT angiogram of the heart, transthoracic echocardiogram, and transesophageal echocardiogram, revealed a cystic mass in the lipomatous interatrial septum. The patient was subsequently diagnosed with a bronchogenic cyst of the interatrial septum. No surgical intervention was pursued, as the mass remained stable, and the cardiothoracic surgeon did not recommend excision. This case highlights a rare case of a symptomatic bronchogenic cyst arising in the interatrial septum diagnosed by imaging modalities. Bronchogenic cysts should be included in the differential diagnosis of intracardiac tumors.

Disseminated Histoplasmosis in a Patient With Acquired Immunodeficiency Syndrome in a Non-Endemic Region (California).

Histoplasmosis is caused by infection with Histoplasma capsulatum (H. capsulatum). Progressive disseminated histoplasmosis is a more severe form of histoplasmosis and is seldom diagnosed in non-endemic regions of the world owing to the fungus's geographical distribution. In the United States (USA), Histoplasma capsulatum is classically known to be endemic to the Mississippi and Ohio River valleys, and cases in non-endemic areas, such as the southwest USA, are exceedingly rare. Patients with acquired immunodeficiency syndrome (AIDS) are at risk for infection with H. capsulatum, and failure to recognize and treat histoplasmosis may be devastating to patients. In non-endemic regions, the proposed mechanism for disseminated histoplasmosis in AIDS patients is reactivation of a previous infection. Here, we present the case of a young male patient who presented to a southern California hospital with diarrhea, was diagnosed with AIDS, and developed acute hypoxic respiratory failure. Chest imaging revealed diffuse reticulonodular opacities, and histoplasmosis was confirmed by urine and serologic examination. He was subsequently treated with liposomal amphotericin B and safely discharged from the hospital with oral itraconazole therapy. This case contributes to the current limited body of literature citing histoplasmosis infections in California, and clinicians should consider histoplasmosis as a differential diagnosis in non-endemic regions.

A Rare Case of a Giant Bladder Stone Associated With Post-obstructive Renal Failure Managed by Open Cystolithotomy.

Urinary tract stones are found in many locations, such as in the kidney or ureter, and, less commonly, in the bladder. Bladder stones are solid calculi that are usually composed of calcified material, most commonly uric acid, and typically weigh less than 100 g. There is a higher prevalence of bladder stones in males than in females, which can be explained by the pathophysiology of how these stones are formed. Namely, bladder stones tend to form secondary to urinary stasis, such as in the setting of benign prostatic hyperplasia (BPH). However, bladder stones can form in otherwise healthy individuals without anatomic defects (e.g., urethral strictures) or urinary tract infections (UTIs). Foley catheters or any foreign bodies in the bladder can predispose to stone formation. Renal calculi, most commonly calcium oxalate or calcium phosphate in composition, can also travel through the ureter and get trapped in the bladder. The most significant risk factors for bladder stones include the presence of BPH and UTIs, both of which favor the development of additional layers of stone material. In exceptionally rare cases, bladder stones measure more than 10 cm in diameter and weigh more than 100 g. These entities have been referred to as giant bladder stones within the limited literature. Minimal data exist on the etiology, epidemiology, composition, and pathophysiology of giant bladder stones. We present the case of a 75-year-old male with a giant bladder stone composed of 100% carbonate apatite, measuring 10 cm × 6 cm and weighing 210 g.

Symptomatic Ventricular Bigeminy and Trigeminy Associated With COVID-19.

Cardiac manifestations of COVID-19 are well-described in the current literature, although electrocardiogram analyses of COVID-19 patients are limited. The most common arrhythmias experienced by patients with COVID-19 include sinus tachycardia and atrial fibrillation. Ventricular bigeminy associated with COVID-19 is exceedingly rare and requires further studies to determine its incidence and clinical significance. Here, we present the case of a 57-year-old male with no prior cardiac history who was found to have COVID-19 and new-onset, symptomatic premature ventricular contraction bigeminy. This case highlights a rare potential association between COVID-19 and ventricular bigeminy/trigeminy.

Atypical Seropositive Striated Muscle Antibody Myasthenia Gravis Presentation With Metastatic B1 Thymoma: A Rare Case.

The association between myasthenia gravis (MG) and thymomas is well-documented. Thymomas are rare epithelial cell tumors that arise from the thymus gland and occur in the mediastinum. Myasthenia gravis is a neuromuscular disorder that causes skeletal muscle weakness due to the presence of anti-acetylcholinesterase antibodies. Roughly 60% of thymomas are associated with MG, while only 10% of MG patients have thymomas. We present an atypical presentation of myasthenia gravis with an associated unusual metastatic thymoma. This case is of a young, previously healthy 26-year-old male with no previous medical history who presented with non-specific symptoms of fatigue, diarrhea, abdominal pain, back pain, blurry vision, and unintended weight loss. He underwent treatment with intravenous immunoglobulins (IVIG), had two surgical resections of the thymoma, and ultimately received radiotherapy. Based on our experience with this case, diagnosing myasthenia gravis by testing for specific muscle antibodies for patients with ptosis in the setting of non-specific complaints, including fatigue, vomiting, diarrhea, and abdominal or back pain, should be considered. Routine imaging should follow with a chest computed tomography to screen for thymomas if the specific anti-titin and anti-ryanodine receptor (anti-RyR) muscle antibodies are positive and myasthenia gravis is suspected. If a thymoma is confirmed, it is best to confirm; and mass characterizes with chest magnetic resonance imaging. A treatment approach of IVIG followed by surgical resection and possible debulking if the lesion is deemed metastatic could also be considered thereafter, especially in young patients with few comorbidities. Treatment with Pyridostigmine 30 mg twice daily for 25 days post-surgically and radiation for treatment of any remaining unresectable tumor should also be considered.

Marijuana-Induced Lung Injury: A Case Report and a Review of the Literature.

Marijuana is a commonly abused illicit substance around the world, and lung injury related to its use has seldom been cited in the literature. Most cases describe marijuana-induced lung injury via vaping and the use of butane hash oil; however, no cases, to our knowledge, have associated lung injury related to marijuana smoke in the form of rolled "blunts" or cigarettes. We describe the case of a patient who presented to the hospital due to chest computed tomography findings demonstrating diffuse bilateral opacifications without signs of systemic inflammatory response syndrome. Bronchoscopy with bronchoalveolar lavage and sputum cultures failed to identify an infectious etiology, and serologies were negative for autoimmune etiologies. We aim to contribute to the limited body of literature describing marijuana-induced lung injury.

Left-Sided Transudative Chylothorax With Concomitant Chylous Ascites in the Setting of Liver Cirrhosis.

Most chylothoraces are caused by trauma and malignancy, and pleural fluid analysis typically demonstrates an exudative effusion. Transudative chylothorax is a rare manifestation and has only been cited in case reports in the current literature. Here, we present the case of a 59-year-old male with a history of liver cirrhosis secondary to alcohol abuse, chronic kidney disease stage 3a, and hypertension who presented with a left-sided pleural effusion and abdominal ascites. A thoracentesis and abdominal paracentesis were performed, and fluid analyses demonstrated a transudative chylothorax with concomitant chylous ascites. In this review, we aim to highlight a rare case of transudative chylothorax and discuss the pathogenesis and management of this condition.

Benefits of Early Thoracic Surgery in the Elderly During the COVID-19 Pandemic: Lessons Learned From Performing a Video-Assisted Thoracotomy.

Elderly patients are often considered poor surgical candidates for intra-thoracic operations due to the number of comorbidities, increased risks associated with general anesthesia, decreased cardiopulmonary reserve, and overall increased frailty. In addition, coronavirus disease 2019 (COVID-19) is a critical psychosocial factor that, through secondary effects, can prevent patients from receiving optimal care. Patients are reduced to having limited contact with family, often a vital support system, which can contribute to feelings of hopelessness, loneliness, and depression. We report the case of a 95-year-old female who presented to the emergency department with increasing supplemental oxygen requirements two weeks after a ground-level fall. She was found to have multiple rib fractures and a left-sided hemothorax. Initial management included aggressive respiratory therapy, multiple pigtail chest tubes, and thrombolytics; however, these measures failed to drain the intrathoracic hematoma. Her care was complicated by the psychosocial and isolation factors of COVID-19 which led to the patient exhibiting symptoms of hopelessness, grief, lack of appetite, and loneliness. As conservative management did not improve her clinical care the patient required a video-assisted thoracoscopic surgery (VATS) to manage the retained hemothorax and facilitate re-expansion of her atelectatic lung. Once the patient was removed from COVID-19 precautions, she was taken to surgery and postoperatively the patient reported minimal pain, participated more in physical therapy, and increased her oral intake. In this unique case, a 95-year-old patient with a hemothorax that was successfully treated with a VATS had her clinical care complicated by the psychosocial implications of COVID-19.

Bronchopulmonary Fistula Development in an Elderly Male With COVID-19 Infection.

COVID-19 pneumonia can cause a wide range of complications including pneumothorax and empyema. However, in severe cases, it can lead to bronchopulmonary fistula (BPF) formation and a persistent air leak due to a connection between the pleural space and the bronchial tree. We report the case of a 77-year-old man with a history of hypertension, who presented to the emergency department for evaluation of dyspnea. Admission labs were significant for a positive rapid antigen SARS-Cov-2 test and elevated troponin I. A chest x-ray demonstrated patchy interstitial opacification and ground glass appearance bilaterally. Within the first 24 hours of presentation, the patient developed a right-sided spontaneous pneumothorax and had a 14 French pigtail catheter placed. The patient subsequently developed a persistent air leak after chest tube placement and required video-assisted thoracoscopic surgery (VATS) with talc pleurodesis and a 32 French chest tube placement. In this unique case, we describe an elderly patient's experience of bronchopulmonary fistula formation as a complication of COVID-19 pneumonia and the successful management of this complication with VATS.

Wound Botulism in the Setting of Pregnancy: A Literature Review and Case Report.

Botulism is a rare neuroparalytic illness caused by Clostridium botulinum that can manifest as a descending flaccid paralysis, progressing from cranial neuropathies to respiratory failure. Wound botulism, constituting a minority of cases, is majorly associated with the injection of black tar heroin (BTH) in the western United States. A patient population of particular concern is pregnant women, who may experience a more severe course due to the physiological changes that occur in pregnancy. Because botulism in pregnancy lacks pathognomic features, physicians should maintain a high clinical suspicion when faced with a pregnant patient with neurological symptoms and a history of BTH use. Here, we report the case of a 25-year-old G3P1A1 female with a history of BTH use who presented with cranial neuropathies and respiratory insufficiency.

Dantrolene Administration in the Management of the Prehospital Patient with Methylenedioxymethamphetamine Overdose: A Case Series and Literature Review.

Methylenedioxymethamphetamine (MDMA) is a psychoactive substance that is used commonly as a recreational drug at rave music festivals. MDMA intoxication can cause a myriad of symptoms and side effects including the manifestation of hyperpyrexia in patients. Hyperpyrexia can mimic a heat stroke and ultimately lead to various forms of end-organ damage. The most common methods used in treating MDMA-induced hyperpyrexia focus on the rapid reduction of core body temperature. Various off-label medications have also been used in combating MDMA-induced hyperpyrexia. Dantrolene is one such medication, although its role in the treatment of MDMA intoxication remains uncertain. This case series preliminarily examines the efficacy of dantrolene in mitigating MDMA-induced hyperpyrexia and potentially reducing the risk of end-organ damage in patients suffering from MDMA overdose. This study focuses on nine patients who presented after ingesting various forms of MDMA at "rave" music events. All patients were found to be hyperthermic in the field with a maximum core body temperature of 109 degrees Fahrenheit. All patients were immediately managed by cooling measures, and seven patients additionally received dantrolene in the field before being transferred to Arrowhead Regional Medical Center. Upon arrival to the hospital, nearly every patient was found to have significantly decreased body temperatures when compared to previously measured body temperatures out in the field. However, nearly all patients in the study were also noted to have laboratory abnormalities consistent with various forms of end-organ damage. The degree and severity of end-organ damage observed in MDMA-induced hyperpyrexia seem to be a function of initial core body temperature. Higher core body temperature tends to correlate with more forms of end-organ damage and a higher severity of end-organ damage. Intervention with dantrolene and cooling measures appeared to have no effect on reducing the risk of developing end-organ damage in this patient population.

Intrapleural Tissue Plasminogen Activator and Dornase Alfa Administration for a Multiloculated Recurrent Malignant Pleural Effusion: A Case Report.

Malignant pleural effusions (MPEs) can often be very difficult to manage despite conservative interventions including thoracentesis and indwelling pleural catheter placement. These effusions can be septated and loculated, leading to complexities in drainage and symptomatic relief for patients. As such, physicians have experimented with the use of tissue plasminogen activator (t-PA) and dornase alfa (DNase) in attempts to drain complex malignant pleural effusions. Although the use of t-PA and DNase has been well studied in the context of empyema, the literature is limited in regards to the use of these medications in MPEs. Here, we present the case of a patient with a history of metastatic lung adenocarcinoma complicated by recurrent MPEs. Bedside ultrasonography revealed a septated fluid pocket in the pleural space of the right hemithorax. An indwelling pleural catheter (IPC) was placed with minimal symptomatic relief. The decision was made to administer t-PA and DNase through the IPC, resulting in the resolution of symptoms and radiographic findings. This case highlights the potential benefit of using t-PA and DNase to help drain complex malignant pleural effusions.

Pantoprazole-Associated Thrombocytopenia: A Literature Review and Case Report.

Proton-pump inhibitors (PPIs) are commonly utilized in the treatment of upper gastrointestinal bleeds (UGIBs) due to their ability to stabilize blood clot formation. PPIs have been shown to reduce rebleeding after endoscopic hemostasis and reduce signs of bleeding at index endoscopy. While PPIs are well-tolerated and commonly administered to patients suffering from acute UGIBs, significant adverse effects may occur. Patients have reported various mild systemic symptoms during short-term PPI use, including headache, rash, dizziness, nausea, abdominal pain, flatulence, constipation, and diarrhea. In general, serious side effects of PPIs tend to be mild during treatment periods under two weeks; however, as the treatment duration increases, side effects have been observed to increase in frequency and severity. PPI-induced thrombocytopenia is an exceedingly rarely reported adverse reaction that remains largely unstudied due to the dearth of patient cases. This adverse effect continues to be a diagnosis of exclusion, and there are no current evidence-based recommendations to approach this complication. Thrombocytopenia increases the risk of rebleeding and hemodynamic instability, which may be devastating to patients suffering from UGIBs. Here, we present a case of thrombocytopenia that began after the introduction of pantoprazole in the setting of a UGIB. The thrombocytopenia resolved promptly after cessation of the medication. We highlight this case to increase awareness of this rare finding given the lack of recommendations for short-term PPI-induced thrombocytopenia.

Diffuse Alveolar Hemorrhage in the Setting of Cytarabine Therapy in a Critically Ill Patient.

Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening pulmonary condition characterized by hypoxemia with progression to respiratory failure, rapid onset of dyspnea, and blood loss anemia. While hemoptysis may be present and corroborates the diagnosis, it is absent in about half of the cases, resulting in a diagnostic challenge with variable presenting symptoms. Imaging findings on chest x-ray or computed tomography (CT) scans are also non-specific, often showing diffuse bilateral alveolar opacities. Because DAH is an under-recognized diagnosis, physicians should maintain a degree of clinical suspicion for DAH in patients with unexplained airspace opacities and no signs of an infectious etiology. This is especially important in higher-risk populations such as patients with hematological malignancies, who have a propensity for thrombocytopenia and coagulopathy compounded by the use of anticoagulants. Patients with hematological malignancies, namely acute myeloid leukemia (AML), are also at risk for drug-induced DAH due to the use of cytotoxic medications like cytarabine. Here, we present the case of a 48-year-old male with a past medical history of AML and myeloid sarcoma who developed shortness of breath after receiving cytarabine chemotherapy. Chest radiography revealed diffuse bilateral infiltrates. He was intubated and underwent flexible bronchoscopy, which resulted in a bloody effluent consistent with DAH. After ruling out infectious etiologies, we reached a final diagnosis of DAH and started the patient on corticosteroid therapy.
