[Solitary necrotic nodule of the liver: about two cases]

Nodular liver lesions mainly consist of tumors. Solitary necrotic nodule of the liver is rare. Preoperative diagnosis is difficult. We report the case of a 43-year old woman undergoing surgery for the treatment of a rectal adenocarcinoma metastatized to the liver. Abdominal CT scan showed liver nodule mimicking liver metastasis. The second case is that of a 56 year-old man undergoing cholecystectomy in whom a liver nodule was detected intraoperatively. In both cases, liver nodule was subcapsular and was resected. Anatomopathological examination allowed the diagnosis of solitary necrotic nodule of the liver. Nonspecific necrotic nodule of the liver should be suspected in liver lesions, even in neoplastic context. Characterization using imaging studies and puncture biopsy of liver lesions can be useful.
