Intratumoral Hemorrhage of Liver Metastasis from a Rectal Neuroendocrine Tumor

A 56-year-old healthy woman was referred to our hospital for abdominal pain. Contrast-enhanced computed tomography (CT) showed a 14-cm-diameter liver tumor with intratumoral hemorrhage. We performed emergent transcatheter arterial embolization. She was referred to hepatic surgeon (M.M.) for resectio...

Description
Summary:A 56-year-old healthy woman was referred to our hospital for abdominal pain. Contrast-enhanced computed tomography (CT) showed a 14-cm-diameter liver tumor with intratumoral hemorrhage. We performed emergent transcatheter arterial embolization. She was referred to hepatic surgeon (M.M.) for resection. Preoperative colonoscopy showed an elevated lesion measuring 2 cm in diameter that was pathologically diagnosed as a rectal neuroendocrine tumor (NET). We performed low anterior resection of the rectum, followed by extended right hepatectomy for all hepatic lesions. Intratumoral hematoma was observed in the largest hepatic lesion (size: 150 mm×100 mm). Microscopy also indicated NET G2. We pathologically diagnosed a liver tumor from a rectal NET that bled spontaneously.
