Imaging performance and preoperative differential diagnosis of multiple myopericytoma in the liver: A case report

Abstract

Myopericytoma is a rare type of benign tumor, which commonly affects all four limbs. The occurrence of myopericytoma in the liver is extremely rare. Myopericytoma with a size of >1 cm in diameter in the liver has not been previously reported. Due to the limited number of cases, the preoperative diagnosis of liver myopericytoma based on laboratory and imaging examinations is difficult. In the present case report, a patient with multiple myopericytoma in the liver, with a maximum diameter of 4.5 cm was described, with accompanying computed tomography (CT) and positron emission tomography/CT (PET/CT) imaging profiles. The aim of the present report was to discuss the preoperative differential diagnosis between myopericytoma and other common liver neoplasms, such as intrahepatic cholangiocarcinoma or liver metastasis.

Primary hepatic myopericytoma coexisting with multiple cystic hepatic lesions: a case report

“…Myopericytoma (MPC) is a rare type of perivascular benign neoplasm characterized by spindle cells with contractile features and varied arrangements around the blood vessels [1]. Myopericytoma can be predominantly found in the skin and soft tissues of the lower and upper extremities, and some reported cases have also shown myopericytoma in the intracranial space, nose, urinary tract, and visceral organs [2][3][4][5][6][7][8]. Cystic hepatic lesions are a group of heterogeneous lesions with diagnoses ranging from benign to malignant, among which a simple hepatic cyst is the most encountered in imaging studies [9].…”
