Summary
Giant sigmoid diverticulum, an uncommon condition, presents as a large gas collection in the abdomen. Imaging like CT and contrast studies are crucial for diagnosis and differentiating it from volvulus.
Area of Science:
- Gastroenterology
- Radiology
- Abdominal Imaging
Background:
- Giant sigmoid diverticulum is a rare condition characterized by an unusually large diverticulum in the sigmoid colon.
- Accurate diagnosis is essential to differentiate it from other causes of abdominal distension and obstruction.
Observation:
- Three cases of giant sigmoid diverticulum are presented.
- Plain radiographs revealed a prominent large gaseous lucency in the lower abdomen.
- Computed tomography (CT) demonstrated a large, gas-filled collection with some fluid content in two patients.
Findings:
- Aspiration and contrast injection in one case confirmed communication with the large bowel.
- The key imaging finding is a large intraluminal or extraluminal gas collection.
- Distinguishing this entity from sigmoid and cecal volvulus is critical.
Implications:
- This case series highlights the characteristic imaging features of giant sigmoid diverticulum.
- Awareness of these findings aids in accurate diagnosis and appropriate patient management.
- Radiologists and clinicians should consider this diagnosis in patients presenting with large abdominal gas collections.
