Multimodal diagnostical challenges in frontal calvarial subcutaneous growing masses: a case description
摘要
Meningiomas are common primary central nervous system tumours. They generally behave like slow-growing masses and are often asymptomatic, being incidentally detected. We describe an unusual case of a small frontal meningioma en plaque with extracranial extension, presenting as a painless frontal swelling due to diploic and periosteal infiltration. Multimodal imaging with ultrasound, CT, and contrast-enhanced MRI enabled a precise diagnosis, histopathology confirmed an atypical grade 2 meningioma; a brief literature review is also provided.
