ABSTRACT

Gangrenous cystitis is an exceedingly uncommon diagnosis characterized by bladder mucosa and submucosal necrosis. The presence of non-specific symptoms and signs complicates the diagnostic process. Necrotizing fasciitis is a rare infection affecting the deep soft tissues, causing progressive destruction of the muscle fascia and rapid systemic spread. This study aimed to elucidate the atypical presentation of rare gangrenous cystitis in the literature, highlighting its potential to lead to necrotizing fasciitis. An 82-year-old female patient was admitted with abdominal and pelvic pain complaints. Computed tomography of the lower abdomen revealed free air-fluid densities in the pelvic region, raising the suspicion of intestinal perforation. Exploratory laparotomy diagnosed the patient with gangrenous cystitis and necrotizing fasciitis. Pathological examination confirmed the presence of necrosis. In patients presenting with acute abdominal symptoms, when free air-fluid levels are observed in imaging studies of the pelvis, rare diagnoses such as gangrenous cystitis should not be overlooked, even if the patient’s history indicates anuria.
