Figure 7. A 27-year-old woman who was treated for pulmonary tuberculosis 5 years earlier came for evaluation of a swelling on the parietal wall. A low attenuation, encapsulated, extraperitoneal collection along the inner aspect of the anterior parietal wall displaces the adjacent capsule of the liver, which otherwise appears unremarkable. This collection was mistaken for a mucocoele of the gall bladder on preliminary ultrasound.
