The aim of this study was to describe the CT scan abnormalities in 15 patients with acute pulmonary coccidioidomycosis. Retrospective analysis of chest CT scans from 15 patients with acute pulmonary coccidioidomycosis was performed. The final diagnosis included the finding of Coccidioides immitis in mycology and/or histopathology, complemented by serology. Two radiologists evaluated the CT scans to study the type, size, profusion and localization of the findings. The final decisions were defined by consensus. CT scans showed multiple bilateral nodules in 13 patients and solitary nodules associated with consolidation in 2 cases. The nodules had ill-defined contours, ranging from 0.5 cm to 3.0 cm in diameter, which were predominant in the lower lobes in 11 cases. Cavitation of nodules was observed in 13 cases and coalescence in 7. Nodule-associated abnormalities were found in 13 cases, comprising interlobular septal thickening (n = 7) and consolidations (n = 6). Other abnormalities included lymph node enlargement (n = 6) and small pleural effusion (n = 2). In conclusion, the main CT finding in patients with acute coccidioidomycosis was that of multiple nodules (0.5-3.0 cm) at the lungs bases; a significant proportion of the remaining cases also showed other abnormalities. A diagnosis of coccidioidomycosis must be considered in patients with multiple lung nodules that are either in, or have recently been transported to, areas of endemic mycosis.

We report a case of infection with New York orthohantavirus in a woman who showed renal impairment and hemorrhage, complicated by hydrocephalus, in Long Island, New York, USA. Phylogenetic analysis showed that this virus was genetically similar to a New York orthohantavirus isolated in the same region during 1993.

There are recent reports of neurological manifestations (NMs) from COVID-191. We present a healthy male who developed multiple strokes likely from direct endothelial dysfunction (ED). CASE PRESENTATION: 66M with GERD presents with 5 days of cough, fever, and chills. He was febrile and hypoxic. Work-up revealed CRP 19 mg/dL, ferritin 594 ng/mL, D-dimer 2.01 mg/L, positive COVID-19 PCR, and normal lipid panel. He had wheezing and no NMs. He was treated with antibiotics, enoxaparin, and oxygen. On day 14 he acutely developed altered mental status, aphasia, and unilateral weakness. CT head revealed acute left ischemic infarct. CTA head/neck revealed proximal left ICA dissection. Aspirin and Atorvastatin were given. Further studies revealed D-dimer 0.4 mg/L, no inheritable hypercoagulopathy, and negative TTE and lower extremity venous duplex. MRI brain confirmed multiple acute infarcts. Left ICA thrombectomy and stent placement were performed. It was found that there was a pseudo-dissection with a ruptured plaque and an overlying thrombus resulting in a 75% stenosis.
