ABSTRACT

Central diabetes insipidus (CDI) is a rare condition characterized by excessive urination and thirst due to vasopressin deficiency. The underlying cause of CDI remains unknown in many cases. Tumors are a leading cause of CDI in young individuals, with germinoma being the most prevalent. We present a case of a 22-year-old male diagnosed with infundibuloneurohypophysitis (INH) of unknown etiology. His pituitary stalk thickening partially responded to high-dose prednisone treatment; however, one year after initial diagnosis, a new pineal region mass was noted on imaging. Further evaluation revealed the mass to be most likely a germinoma. This case emphasizes the importance of ongoing clinical and radiologic follow-up in idiopathic cases of CDI. The patient's symptoms improved with desmopressin, but the presence of the pineal mass necessitates further comprehensive neurosurgical evaluation.

ABSTRACT

Pneumoconiosis is associated with coal dust particles depositing within the lung causing nodules coalesce to form progressive massive fibrosis (PMF). Cavitary lesions can develop in these PMF areas for concerns of tuberculosis and aspergillosis. We present a 59-year-old patient who had coal workers pneumoconiosis and PMF presenting with chronic dyspnea and hemoptysis with an upper cavitary lesion noted on chest imaging. He notes dyspnea with walking very short distances with associated productive cough. He admits to occasional wheezing, paroxysmal dyspnea, hemoptysis, and orthopnea but denies chest pain. He is an everyday smoker. His physical examination was only remarkable for bronchial breath sounds. On review of his prior imaging, he had a right upper lobe infiltrate as far back as 2012. As the years progressed, a new cavitary lesion developed in the PMF area which progressively got larger with a thick wall and no eccentric region noted inside the cavity. Tuberculosis test was negative. He underwent a transbronchial biopsy with methenamine silver stain which showed acute angle branching and septation suggestive of Aspergillus species. He was diagnosed with pulmonary aspergillosis and treated with voriconazole for 1 year. With pneumoconiosis and evidence confirming aspergillosis, the presence of a new lung infiltration with progression into a cavitary lesion leads to a diagnosis of chronic cavitary pulmonary aspergillosis (CCPA). With follow-up imaging showing extensive lung fibrosis, he had chronic fibrosing pulmonary aspergillosis (CFPA), a late-stage manifestation of CCPA.

ABSTRACT

We present the case of a 56-year-old woman who was diagnosed with severe coronavirus disease 2019 (COVID-19) pneumonia complicated by severe acute respiratory distress syndrome who was intubated for 19 days. She recovered from COVID-19 after a month. A computed tomography (CT) scan of the chest, after a month, showed improved infiltrates with a small residual cavity within the lingula. A CT angiogram showed a more confluent density in the lingular portion on follow-up 2 months later. She developed intermittent hemoptysis after 3 months in December 2020, which persisted for almost 6 months, and CT of the chest showed the lingular nodular with resolution of the cavitation. She underwent bronchoscopy with bronchoalveolar lavage, confirming Aspergillus fumigatus by galactomannan assay and histology showing branching hyphae. Once she started treatment with itraconazole, her hemoptysis resolved. The follow-up CT of the chest after 2 months of treatment did not show a cavity or a nodule in the lingula. Our patient developed invasive pulmonary aspergillosis (IPA) as a sequela of severe COVID-19 infection. COVID-19-associated invasive pulmonary aspergillosis (CAPA) is an underrecognized complication that needs to be investigated on whether prophylactic treatment is required. Our case also demonstrates that the diagnosis of IPA needs to be considered months after COVID-19 infection when a superimposed fungal infection can occur after a viral infection if the patient continues to have persistent symptoms.

ABSTRACT

Immunotherapy is on the rise as a treatment option for advanced melanoma, non-small cell lung carcinoma, renal cell carcinoma, and melanoma among others. It consists of two main classes being cytotoxic T lymphocyte antigen 4 (CTLA 4) inhibitors and programmed cell death 1 (PD 1) inhibitors. We report a case series of four patients who were started on either pembrolizumab or nivolumab for the treatment of melanoma or lung cancer. While on immunotherapy, they developed various side effects related to the immunotherapy including pneumonitis, transaminitis, thyroiditis, nephritis, and hypophysitis. To treat this complication, immunotherapy must be discontinued or held with immunosuppressant initiation as treatment. Most often the immunosuppressant of choice is steroids. After symptoms improve, patients can decide along with the clinician on restarting or completely stopping immunotherapy. Within our case series, three of four patients had resolutions of their symptoms with steroid treatment with one who was lost to follow up. Of the three patients who were being followed up, one had a relapse of side effects after resuming immunotherapy and decided against further treatment with immunotherapy. Another patient is doing well resuming immunotherapy on a daily dose of steroids. The last patient decided to not continue with immunotherapy after experiencing a flare of his symptoms when he was being treated since he missed a few doses of steroids. Further research is needed about the risk of flares of complications when resuming immunotherapy alone or with immunotherapy and steroid treatment.
