Rupture of a hepatic adenoma in a young woman after an abdominal trauma: A case report

引用

World Journal of Gastroenterology 2013年第27期19卷 4422-4426页

作者： Ricardo Lemos cotta-Pereira Luana Ferreira Valente Daniela Goncalves De Paula Antnio Luís Eiras-Araújo Antnio carlos Iglesias Department of Surgery Federal University of Rio De Janeiro State (UNIRIO) Department of Surgery Militar Police Hospital (HPMRJ) Rio de Janeiro Department of Radiology Federal University of Rio de Janeiro (UFRJ) and Instituto D'Or

Unlike hepatic haemorrhage following blunt abdominal trauma, spontaneous abdomen bleeding is rare, even in the presence of a hepatocellular adenoma (HA) or carcinoma. However, the diagnosis of a tumour underlying a haematoma after liver trauma is unusual, especially when it occurs more after two years after the accident. Here, we report a case of a ruptured HA due to blunt abdominal trauma. A 36-year-old woman was admitted to our hospital with sudden onset of upper abdominal pain. Her medical history revealed a blunt abdominal trauma two years prior. Initial abdominal computed tomography scan revealed a large haematoma measuring more than 16 cm in diameter in the right lobe of the liver. Magnetic resonance imaging showed haemorrhagic areas and some regions with hepatocyte hyperplasia, suggesting HA. The patient underwent right hepatic lobectomy, and a histopathological examination confirmed a diagnosis of HA. In conclusion, it is important to consider that abdominal trauma may hide old, asymptomatic and not previously detected injuries, as in the case reported.
