Atypical presentation for a gastrointestinal basidiobolomycosis and rare side effect of Voriconazole: A case report and literature review.

Gastrointestinal basidiobolomycosis (GIB) is a rare fungal infection often misdiagnosed with other gastrointestinal disorders. We report a case of a 6-year-old boy from Saudi Arabia who presented with fever, abdominal pain, and weight loss, initially suspected to have inflammatory bowel disease. Despite antibiotics, symptoms persisted, leading to a GIB diagnosis with liver involvement. IV voriconazole improved his condition but caused visual hallucinations, managed by dose adjustments. This case underscores the need for early suspicion of GIB in endemic areas and highlights the importance of prompt diagnosis and a multidisciplinary approach to improve outcomes and reduce complications.
