Recurrent Meningeal Hemangiopericytoma with Multiple Metastasis and Hypoglycemia : A Case Report

Abstract EN

Aims.

We report on the unusual case of a 43-year-old man who developed recurrent meningeal hemangiopericytoma and presented with hypoglycemia 6 years after excision of the tumor.

Methods and Results.

We utilized computed tomography to assure multiple tumor metastasis and cranial recurrence of previous meningeal hemangiopericytoma and clinical laboratory tests and immunohistochemical staining to characterize this case.

Magnetic resonance imaging and computed tomography showed the recurrent tumor at original torcular site was increased in size.

Abnormal low levels of growth hormone, insulin, and insulin-like growth factor-I except insulin-like growth factor-II were detected in the serum.

By immunohistochemistry, the neoplastic cells characteristically express diffusely CD99, bcl2, and variable CD34.

After radio- and chemotherapy, serum glucose level of the patient returned to normal.

Conclusions.

Comparing other brain tumors, meningeal hemangiopericytoma has a higher recurrent and metastatic rate, but this tumor with hypoglycemia is very rare.
