Chronic expansive retroperitoneal hematoma is a hematoma that grows progressively sometime after the original trauma. It can appear in different locations. The mechanism of onset is unclear, but experimental evidence favours an inflammatory cause. For diagnostic imaging, magnetic resonance imaging is more useful than computed tomography (CT). However, it is difficult to differentiate it from other soft tissue tumors, sarcomas, actinomycosis or inflammatory pseudotumors, due to the uneven central uptake. Histopathological analysis of the lesion usually shows a dense fibrous tissue capsule containing numerous old clots without finding clear atypia or signs suggestive of malignancy. The treatment of choice is complete resection of the lesion (including the capsule), as incomplete treatments (such as drainage or curettage of the hematoma contents) may cause recurrence.
