Giant-cell glioblastoma

Giant-cell glioblastoma is a rare and distinct variant of glioblastoma, characterized by the presence of large, bizarre, multinucleated giant cells. It accounts for less than 1% of all glioblastoma multiforme (GBM) cases. Despite its histological uniqueness, its clinical behavior and prognosis are similar to those of conventional GBM.

Clinical Presentation[edit]

Patients with giant-cell glioblastoma typically present with symptoms related to increased intracranial pressure, such as headache, nausea, vomiting, and seizures. Neurological deficits may also occur, depending on the location of the tumor.

Diagnosis[edit]

The diagnosis of giant-cell glioblastoma is based on histopathological examination of the tumor tissue obtained during surgery. The tumor is characterized by the presence of large, bizarre, multinucleated giant cells, along with areas of necrosis and vascular proliferation.

Treatment[edit]

The treatment of giant-cell glioblastoma is similar to that of conventional GBM and includes surgery, radiation therapy, and chemotherapy. However, the prognosis remains poor, with a median survival of approximately 12 months.

Prognosis[edit]

Despite its histological uniqueness, the prognosis of giant-cell glioblastoma is similar to that of conventional GBM, with a median survival of approximately 12 months.
