Case Report and Review of the Literature of Schwannomas That Originate from Falx Cerebri

Schwannomas not related to cranial nerves are rare. Here, we present a case of a schwannoma that originated from the falx cerebri and review reported cases in the literature. A 36-year-old male experienced generalized seizures following right hemiparesis predominantly in his lower extremity. Magneti...

Summary:Schwannomas not related to cranial nerves are rare. Here, we present a case of a schwannoma that originated from the falx cerebri and review reported cases in the literature. A 36-year-old male experienced generalized seizures following right hemiparesis predominantly in his lower extremity. Magnetic resonance imaging revealed a round tumor attached to the falx cerebri on the left side. Radiologically, the tumor appeared to be a falx meningioma. We performed gross total removal of the tumor. Pathology showed a schwannoma that originated from the falx cerebri. Right hemiparesis disappeared soon after surgery. Although distinguishing a schwannoma of the falx cerebri from a falx meningioma and metastasis is difficult preoperatively, inclusion of schwannoma of the falx cerebri in the differential diagnosis is important, especially when the patient is relatively young and/or the tumor lacks a dural tail sign.
