Fatal strokes in patients with rhino-orbito-cerebral mucormycosis and associated vasculopathy.
Within a 10-y period, fatal strokes occurred during parenteral administration of amphotericin B and surgical debridement of paranasal sinuses in 6 pathologically verified cases of rhino-orbito-cerebral mucormycosis (ROCM). All patients had unnoticed type-2 diabetes mellitus without ketoacidosis. They presented with unilateral orbital cellulitis and cavernous sinus syndrome. Fatal malignant cerebral infarctions occurred in the carotid system in 5 patients, and in the basilar artery or its major branches in 2 patients. Accelerated thrombotic occlusion of the cavernous portion of the carotid artery or the basilar artery was likely to be due to mucormycosis associated-vasculopathy and diabetic vasculopathy. One patient died of massive subarachnoid hemorrhage following rupture of the mycotic aneurysm. Despite parenteral administration of amphotericin B, fatal outcome of ROCM in patients with unnoticed diabetes mellitus occurs due to mucormycosis-associated malignant strokes. To improve outcome, a combination of early radical debridement, ocular exenteration, parenteral and local administration of amphotericin B, and decompression craniotomy should be considered.
