Abstract

Meningiomas are the most common intracranial tumors. However, microcystic and angiomatous meningiomas are very rare subtypes that present unusual imaging findings. Hence, radiological diagnosis of these tumors can be challenging. We herein describe a case of mixed angiomatous and microcystic meningioma in an 81-year-old male. MRI revealed an extra-axial mass with high T2 signal intensity, measuring 1.5 cm in diameter, with multiple tiny intralesional cysts and entrapped peritumoral cyst formation. After tumor resection, a histopathological diagnosis of mixed angiomatous and microcystic meningioma was made.

수막종은 가장 흔한 두개내 종양이지만, 그 아형인 미세낭종성 및 혈관종성 수막종은 매우 드물고 특이한 영상 소견으로 인해 영상의학적 진단이 어려울 수 있다. 이에 저자들은 미세낭종성 혈관종성 혼합 수막종으로 진단된 81세 남자 환자 증례를 보고하고자 한다. 자기공명 T2 강조영상에서 병변은 왼쪽 전두부에 약 1.5 cm 크기의 고신호강도의 축외 종양으로 보이고 있었고, 종양 내에 다수의 아주 작은 낭종들이 관찰되었으며, 종양 주위로 포획된 큰 낭을 형성하고 있었다. 수술적 절제를 통한 병리 검사상 미세낭종성 혈관종성 혼합 수막종으로 최종 진단되었다.
