A Case of Giant Cutaneous Lopez Type III Meningioma of the Scalp

Abstract

Meningiomas are the most common central nervous system (CNS) tumors. Extracranial meningiomas are rare, constituting 2% of all meningiomas. We describe a case of Lopez type III meningioma of the scalp in a 72-year-old gentleman who had a long-standing giant scalp mass and presented with recent mild left-sided limb weakness and numbness. Magnetic resonance imaging (MRI) of the skull demonstrated a right frontoparietal tumor extending through the skull into the scalp. Tumor excision revealed World Health Organization (WHO) grade 1 meningioma. Clinicians should correlate a cutaneous skull mass and new onset of neurological symptoms. Cutaneous meningioma is an important differential diagnosis.

Humps and bumps of head: review of meningiomas of the scalp

“…The prognosis of cutaneous meningiomas is largely determined by the Lopez lesion type. Type I has a favorable prognosis if are achieved clear surgical margins intraoperatively [ 55 ]. Furthermore, no tumor recurrences have been reported after the complete surgical resections [ 33 ].…”
