This 64 year old female patient underwent sonographic imaging of the abdomen. Ultrasound image (right) shows an echogenic, rounded mass lesion in the caecum. CT scan of the pelvis (Left) reveals a fat density mass in the caecum. These images suggest a diagnosis of lipoma of the caecum. Caecal lipomas are usually seen in elderly female patients and are usually symptomatic if their size is more than 3 cms. They can often cause intussusception.
