ABSTRACT
Introduction: COVID-19, a new coronavirus illness, swiftly spread throughout all continents. However, evidence on all of COVID-19's indications and symptoms is lacking. Patients who have COVID-19 may be more susceptible to fungal infections. Mucormycosis is an uncommon and frequently fatal fungal illness caused by hyphae invading the bloodstream and causing thrombosis and necrosis. Material(s) and Method(s): Patients diagnosed with mucormycosis following a recent COVID-19 infection were included in the case series analysis. Surgical therapy was limited to individuals who tested negative for COVID-19 on PCR. To remove the infection, endoscopic, open, and combination techniques were used. For the first month after surgery, survivors were followed up on on a regular basis. Result(s): About 30 people with a history of Covid-19 were given dexamethasone and remdesivir in this study. Following therapy, these individuals developed mucormycosis, which was treated by Functional Endoscopic Sinus Surgery (FESS). As a consequence, 16 patients (53.34 %) had numerous operations. The most prevalent related condition was diabetes mellitus (60 %). The majority of the patients were men (60 %). Our patients had an average age of 55.53+/-8.093. 43.34 % of the people died. Conclusion(s): In conclusion, mucormycosis is a rare but critical problem complicating the later part of the clinical course of COVID-1, possibly due to improper drug usage during Covid treatment.

ABSTRACT
Introduction: The pandemic of COVID-19 in association with mucormycosis would be a deadly fungal infection with high level of mortality and morbidity. Our aim is to evaluate the surgical outcome of patients with rhino-orbito-cerebral mucormycosis to suggest better management strategies. Method(s): A total of 62 cases of COVID-19-associated rhino-orbito-cerebral mucormycosis were admitted to the ear, nose, throat department in Mashhad, Iran, from August 1 to October 15, 2021. All data were analyzed using SPSS version 27.0. Descriptive analysis was used for demographic and clinical characteristics. Result(s): Main predisposing conditions were diabetes mellitus (90%) followed by hypertension (41%). Main symptoms were headache (75%), periorbital or retro-orbital pain (61%), visual loss (45%), and facial numbness (41%). Mucosal and ocular findings showed necrosis (67%), blindness (n=35), ptosis (n=31), proptosis (n=27), ophthalmoplegia (n=25), and chemosis (n=20). Neurologic loss of consciousness (19%) and palsies of cranial nerves (53%) were observed. Endoscopy findings showed necrosis (70%), discharge (61%), and crusting (54%). Imaging enhancement revealed mucosal thickening (69%), opacification of sinus (69%), bony destruction of sinus (35%), and orbital involvement (25%). Debridement surgery was necessary in nearly all patients (96%), dominated by ethmoid sinus (90%), maxillary sinus (87%), middle turbinate (80%), and sphenoid sinus (79%). Based on our follow-up, 25 patients died (42%). Those who survived will suffer from no light perception (35%), cranial nerve palsy (12%), and cerebral vascular accident (1.6%). Conclusion(s): Mucormycosis is an aggressive fungal infection. Diabetes mellitus, COVID-19 complication, inappropriate use of corticosteroids, and delayed vaccination had significantly increased its incidence. As there is an urgent need to address this public health concern, we present our data set from Iran.
ABSTRACT
CASE: A 44-year-old male with past medical history of type II insulindependent diabetes mellitus (DM) and end stage liver disease (ESLD) due to alcohol use and nonalcoholic fatty liver disease (NAFLD) presented with one week of left-sided retroorbital headache and diplopia. Two weeks prior, the patient tested positive for COVID-19 and initially his severe headache was attributed to this diagnosis. On hospital presentation the patient was found to have ophthalmoplegia, ptosis and diminished sensation in the CN V1 distribution on the left. The patient was in diabetic ketoacidosis (DKA) with glucose of 686, venous blood gas of 7.32/29/15 and serum anion gap of 17. Contrasted orbital and maxillofacial CT showed complete opacification of the left sphenoid sinus and CT angiography/venography of the head were negative for venous sinus thrombosis. MRI of the brain showed left optic nerve ischemia and left frontal lobe cerebritis without abscess. Bedside nasal endoscopy with ENT showed purulent, fuzzy white debris bilaterally concerning for fungal sinusitis. He was taken urgently to the operating room and was found to have angioinvasive fungal sinusitis with cultures growing Lichthemia corymbifera, a fungus in the Mucor family. In addition to treatment with IV insulin and fluids for DKA, the patient was given amphotericin B and posaconazole;however, surgical intervention was deemed too high risk and futile in the setting of patient's comorbidities. IMPACT/DISCUSSION: Mucormycosis is a fungal infection that typically involves the sinuses, orbits and the central nervous system (CNS). Infection of the sinuses manifests with fever, sinus congestion/pain and headache, but can rapidly progress to involve the orbits, leading to vision changes, and the CNS, leading to encephalopathy. Other structures that can be involved include the cavernous sinus, leading to palsies of cranial nerves III-VI. Known risk factors for mucormycosis include DM, especially in patients with DKA, glucocorticoid treatment, immunosuppression and deferoxamine use. Urgent histopathologic diagnosis, initiation of intravenous antifungal agents (amphotericin B) and surgical intervention with ENT, ideally prior to extension beyond the sinuses, are fundamental to decreasing mortality, which is as high as 62%. There have been numerous case reports of mucormycosis in patients with COVID-19, particularly from India. Many of these patients were prescribed glucocorticoids as part of the COVID-19 treatment pathway or had underlying DM. Additional research is needed into the association between COVID-19 and invasive mucormycosis. CONCLUSION: In patients with poorly controlled DM or immunosuppression presenting with severe headache, sinus pain, and/or neurologic changes, mucormycosis must be considered, as it is a fatal entity requiring urgent surgical intervention and initiation of antifungal agents. Patients with COVID-19 infection may be at increased risk for mucormycosis, especially in those with underlying DM or on glucocorticoids.
ABSTRACT
Objectives: (1) Present a case of visual decompensation related to a Rathke's cleft cyst (RCC) in setting of acute COVID-19 infection. (2) Review the literature on the presentation and management of RCCs. Study Design: Case report and review of the literature. Results: We report a case of a 32-year-old female diagnosed with a sellar mass who was transferred from an outside hospital for acute visual field decompensation. Upon arrival, the patient reported a decline in vision over the past 3 days, photophobia, and diplopia with physical exam confirming these findings. Of note, patient was unvaccinated and laboratory testing revealed that she was COVID-19 positive with mild symptoms of congestion. Imaging revealed a large intrasellar and suprasellar T1 hyperintense mass with displacement of the optic chiasm superiorly ([Fig. 1]). An endoscopic transsphenoidal approach was performed and the cyst was marsupialized into the sphenoid sinus decompressing the optic chiasm. Cultures demonstrated many white blood cells, but no organisms. Pathology confirmed a diagnosis of RCC. There was no intraoperative cerebrospinal fluid leak noted. To prevent reaccumulation of cyst contents, a free mucosal graft harvested from the posterior septectomy and was used to line the sellar defect to facilitate marsupialization into the sphenoid sinus. Postoperatively, physical exam revealed normalization of her vision and extraocular movements, and the patient subjectively confirmed these findings. She was discharged home on postoperative day 3 without complications. Review of the literature demonstrates that visual field deficits are a common presenting finding in RCC patients and acute inflammation of RCCs can present similarly to pituitary apoplexy. Transsphenoidal approaches are safe and effective in surgical decompression of RCCs. Lining the exposed cyst cavity with a free mucosal graft or nasoseptal flap may facilitate promotion of an epithelialized track to prevent cyst reaccumulation. Conclusion: A case of acute visual decompensation related to a RCC in setting of acute COVID-19 infection is presented. Inflammation of the RCC, presumably related to COVID-19 infection, contributed to the acute presentation. Endoscopic transsphenoidal approaches are effective at decompression of RCCs and free mucosal grafts or nasoseptal flaps may promote epithelialization of a tract to decrease recurrences.
