ABSTRACT
BACKGROUND: Mucormycosis is a rare, aggressive fungal disease with high mortality, typically presenting as rhinosinusitis in immunocompromised patients. CASE DESCRIPTION: A 43-year-old man with a history of intravenous drug use, Hepatitis C, and no evidence of immunocompromise presented with worsening balance problems. He had received intravenous antibiotics 2.5 years earlier for local infection after injecting heroin into a neck vein. Imaging studies revealed a lesion, likely of neoplastic origin. At resection, purulent fluid sampled by neuropathology revealed right-angled, branching hyphae, suggesting mucormycosis. No further resection was performed, no other disease sites were found, and HIV findings were negative. Two weeks postoperatively, he developed renal failure; intravenous antifungal treatment and hemodialysis were discontinued. When kidney function recovered 2 weeks later, he declined additional treatment. CONCLUSION: In our immunocompetent patient, both the location of the infection in the posterior fossa and its slowly progressive characteristic were unique variations of this typically aggressive disease.
ABSTRACT
We report our experience with resident preliminary interpretations given at night on both abdominal and neurological CT scans to quantify the discrepancy rate when compared to the final report. An attempt was also made to document any adverse clinical outcomes as a result of the preliminary interpretation. From January 1, 2004 to December 31, 2004, adult CT examinations were prospectively interpreted by residents at night at a level I trauma center. Both the neurological and body CT scans were reviewed beginning at 7:00 a.m. the following morning by the respective subspecialty staff and discrepancies were noted. Adult CT examinations (6,858) were prospectively interpreted by residents: 5,206 cranial spinal CT examinations and 1,652 body CT examinations. Among the neurological studies, there were six cases identified as major discrepancies (0.1%) and 185 minor discrepancies (3.5%). Among the body CT cases, there were seven cases identified as major discrepancies (0.4%) and 23 cases of minor discrepancies (1.4%). There is a low discrepancy rate (0.2% major and 3.1% minor) in the preliminary resident interpretations from the final report. The process of overnight preliminary CT interpretations should continue as it is not substandard care.
