Bulky cardiac metastasis of intracranial solitary fibrous tumor/hemangiopericytoma: Delayed metastasis after cranial tumor resection

Blog Article

We report a case of bulky cardiac metastasis of intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC).A 72-year-old woman developed a chief complaint of chest pain.Contrast-enhanced computed tomography revealed multiple enhanced masses in the heart, retroperitoneum, and femur.

Initially, multiple metastases of Stainless Tubing cardiac primary angiosarcoma were suspected because the cardiac mass was the largest.However, it was diagnosed as SFT/HPC on the basis of biopsy and immunostaining for the retroperitoneal lesion.She had a history of resected brain tumor surgery for a meningioma 11 years earlier, and pathological reconfirmation revealed this was not a meningioma but rather a AEG DLE0970M 90cm Designer Island Hood – CHROME SFT/HPC.

Thus, we found that the enhanced masses were extracranial metastases of an intracranial primary SFT/HPC.She died approximately 3 years after the onset of chest pain.Autopsy confirmed metastasis in the retroperitoneum, liver, lung, mesentery, skeletal muscle, and bone in addition to the heart.

SFT/HPC has been reported to easily recur locally and to show systemic metastasis over the long term.Given that SFT/HPC has been recognized as a subtype of meningioma, the differential diagnosis for patients with a history of intracranial tumors, such as meningioma, should include SFT/HPC.Keywords: Solitary fibrous tumor, Hemangiopericytoma, Meningioma, STAT6, Cardiac metastasis, Delayed metastasis.
