Mucormycosis Causing Splenic Infarction, Gastric Fistula, and Brain Abscess in a Patient With Acute Myeloid Leukemia: A Case Report.

Abstract

Invasive mucormycosis is an aggressive fungal infection characterized by rapid progression, primarily impacting immunocompromised individuals. Herein, we report a case of splenic infarction in association with gastrointestinal fistula and brain abscess as a rare presentation of mucormycosis biopsy, proven in a 56-year-old patient diagnosed with acute myeloid leukemia. The patient initially sought medical attention with a 3-week history of fever, night sweats, and malaise. Considering the chest computed tomography findings compatible with fungal disease and neutropenia, he underwent broad-spectrum antifungal therapy. Following the occurrence of splenic infarctions and a gastric fistula, the patient underwent a partial gastrectomy and splenectomy. Despite the interventions, the patient did not have a successful outcome and died on the second postoperative day. This case highlights the importance of timely suspicion, immediate antifungal therapy, and surgical intervention to improve the survival prospects of patients with multifaceted manifestations of mucormycosis.
