Schwannomas are a type of neurogenic neoplasm generating from the nerve sheaths of the peripheral nerves. They usually occur in the head, neck, and flexor surfaces of the upper and lower extremities. Schwannomas occurring in the abdominal cavity are rare, and are most commonly located in the alimentary tract, i.e., stomach, colon and rectum [1]. Schwannomas originating from the abdominal arteries are quite rare but possible because of the networks of sympathetic and parasympathetic nerve fibres present on vessel walls. A 45-year-old female patient suffering from persistent upper abdominal pain was admitted to our surgery department. A CT scan showed an 8 cm × 7 cm mass located in the porta hepatis which surrounded the proper hepatic artery (Fig. 1). During surgery, the lesion was found to be in close contact with the common hepatic
artery, the proper hepatic artery (which was totally encroached by the lesion), and the gastroduodenal artery (Fig. 2). The tumour was macroscopically resected en-bloc with the proper hepatic artery and the gastroduodenal artery. Due to the presence of a right hepatic artery arising from the superior mesenteric artery, no vascular reconstruction was performed. The histopathological diagnosis of the resected specimen was arterial-origin schwannoma. The postoperative period was uneventful, and the patient was discharged 6 days post-operatively. After 3 years of follow-up, no relapse was observed. Reference [1] Sarlomo-Rikala M, Miettinen M. Gastric schwannoma: a clinicopathological analysis of six cases. Histopathology 1995;27:355–60.
