Acute isolated cerebral mucormycosis in a patient with high grade non-Hodgkins lymphoma

A 57-year-old female in complete remission of grade IV non-Hodgkin lymphoma whilst on intensive chemotherapy, suddenly developed unilateral hemispheric stroke with a fatal outcome in 3 days. She was apyrexial and had received antifungal prophylaxis during her treatment. Post-mortem examination showed complete thrombosis of the internal carotid artery leading to infarction in the territory of the middle and anterior cerebral arteries. Microscopic examination of the brain showed involvement of intra-cranial vessel walls and brain parenchyma by mucormyces, with no evidence of systemic mucormycosis. Isolated cerebral mucormycosis is a rare occurrence, more commonly found in intravenous drug abusers, but can occur in patients with haematological malignancy.
