Abstract

A 58-year-old woman visited a local doctor for body weight loss. Examinations revealed a retroperitoneal tumor, and she visited our hospital. CT showed a low-density, round, 9.4-cm mass in the retroperitoneal space behind the liver ; the tumor displaced the inferior vena cava and right hepatic vein to the anterior side. Hematological studies, including that for adrenal function, showed almost normal status. Tumor resection was performed based on the diagnosis of a retroperitoneal tumor in September 2011. The tumor could be divided from the inferior vena cava and hepatic vein smoothly, but it was difficult to divide the tumor from the right adrenal gland, and right adrenalectomy was required. Histopathological findings showed that it was a neurofibroma. Solitary retroperitoneal neurofibromas without neurofibromatosis I (von Recklinghausen disease) are reported to be rare rare. We present this case and include a review of the literature.
