Encysted intrapelvic hematoma invading the iliac bone: A case report

Encysted intrapelvic hematoma is rare [2]. The etiological diagnosis is often difficult but guided by computed tomography and magnetic resonance imaging (MRI) and confirmed by histopathological examination. A 40-year-old man was admitted for a painless iliac fossa with mass evolving for 6 months. In his medical history, he had an exploratory laparotomy following a road accident 20 years ago. Radiological investigation shows a process centered on the lysed left iliac bone, multi-loculated in favor of encysted hematoma. Histopathology confirmed the diagnosis. The treatment was a simple resection and drainage of the mass. No local recurrence was noted, after 24 months of follow-up. Before an unexplained polycystic mass, the diagnosis of encysted hematoma should be considered, especially in any patient presenting pain next to a mass with risk factors as an old trauma. Currently there is no consensus in the treatment, but surgery still has a place in the management, also making it possible to eliminate other pathologies, namely tumors.
