“…In the pathologic and genetic categorization in the 2002 World Health Organization classification of soft-tissue tumors, myopericytoma is classified as an independent type of angiopericytoma [ 2 ]. Its histologic features include a concentric perivascular distribution of ovoid, tubular, spindled, and/or oval-to-spindle shaped cells with eosinophilic cytoplasm and a myoid appearance [ 3 ]. Because of its morphological similarities to a perivascular myoid neoplasm, myopericytoma may be under-recognized by surgical pathologists.…”

A 49-year-old female with history of headache, nausea and vomiting with some weeks of evolution, without neurological symptoms. Radiology revealed an expansive lesion near the inferior vermix and cerebellar tonsils, with heterogeneous gadolinium uptake and mass effect on the fourth ventricle, representing a probable extraventricular origin for the lesion. Pathological examination showed a proliferation of oval/spindle cell proliferation with eosinophil cytoplasm and small and monotonous nuclei, without mitoses. The cells had a concentric growth, surrounding thin-walled blood vessels with foci of stromal myxoid degeneration and whorled pattern. The vessels had a haemangiopericytoma pattern and were lined by non-atypical endothelial cells. The tumorous cells expressed vimentin, alpha-smooth actin and heavy-chain caldesmon and were negative for epithelial membrane antigen, protein S100, HMB45, CD34, calponin and desmin, thus providing the final diagnosis of intracranial myopericytoma.

“…In the reports, small lesions usually showed significant enhancement overall, while some large lesions showed peripheral enhancement due to central ischemic necrosis. In conventional MRI, T1WI, lesions usually showed hypointensity or slight hypointensity, T2WI had hyperintensity, and the signal was heterogeneous [ 5 , 13 , 16 , 25 ]. On contrast-enhanced MRI, the lesions showed severe enhancement [ 5 , 13 , 21 ].…”

“…On contrast-enhanced MRI, the lesions showed severe enhancement [ 5 , 13 , 21 ]. When the vertebral body was involved, there was an osteolytic lesion and it could be compressed to the spinal cord [ 12 , 16 , 25 , 26 ]. Lesions occasionally had hemorrhage [ 13 ] or lymph node enlargement [ 15 ].…”

BackgroundMyopericytoma is a rare and usually benign tumor, which is even rarer if it occurs in the liver and stomach space. Previous reports of myopericytoma were mostly related to its pathological manifestations, while imaging reports were rare. Here, we report the computed tomography (CT), computed tomography angiography (CTA) and magnetic resonance imaging (MRI) performance for one deep myopericytoma.Case presentationIn this study, one deep myopericytoma in the liver and stomach space is reported. A CT that was not contrast-enhanced showed a lobulated tumor with heterogeneous density, and a contrast-enhanced CT showed that the mass had progressive enhancement. CTA showed that the blood-supply of the tumor was supplied by the anterior superior pancreaticoduodenal artery and the left gastric artery. An MRI showed the lesion had isointensity on T1-weighted imaging (T1WI) and slight hyperintensity on T2-weighted imaging (T2WI). The lesion MRI enhancement characteristics were similar to the characteristics from the contrast-enhanced CT. In this case, the enhancement pattern of the tumor was the centrifugal enhancement for both the contrast-enhanced CT and MRI. After surgical resection of the tumor, the pathological diagnosis was myopericytoma, and there was no recurrence in a short-term follow-up.ConclusionThe myopericytoma generally has a rich blood supply. When there is necrosis in the center lesion, the lesion has peripheral enhancement. Abdominal myopericytoma could be categorized as having centrifugal enhancement.
