Solitary rectal diverticulum: A rare entity mimicking contained perforation – Imaging and surgical correlation

Solitary rectal diverticulum is a rare entity, often asymptomatic and discovered incidentally. It may arise from congenital anomalies or acquired causes, including prior surgical interventions. Despite its rarity, complications such as diverticulitis, abscess formation, and fistulas can occur, mimicking more severe conditions such as perforation or perforated mass. Accurate diagnosis relies on precise imaging and pathology. Recognizing its distinct features is crucial for proper management, optimizing patient outcomes, and preventing misdiagnoses that could lead to inappropriate treatment strategies.
