장종창,강병성,서재희,차재룡,황재철,원영철,신상훈 대한영상의학회 2009 대한영상의학회지 Vol.61 No.2
A trichilemmal carcinoma is a rare superficial tumor occurring on the sun-exposed regions of older individuals. We examined a 79-year-old female with a large mass located in the right posterolateral aspect of the patient’s neck. The MR images showed a central cystic portion with intense peripheral enhancement. The histopathologic examination of the resected specimen revealed a trichilemmal carcinoma. Here, we report the MR findings of the trichilemmal carcinoma in this patient.
Adult Pilomyxoid Astrocytoma Mimicking a Cortical Brain Tumor: MR Imaging Findings
장종창,원영철,서재희,김영,황재철 대한영상의학회 2010 대한영상의학회지 Vol.62 No.4
A pilomyxoid astrocytoma (PMA) is a recently identified low-grade neoplasm that was previously classified as a pilocytic astrocytoma (PA), yet demonstrates unique histological features and more aggressive behavior. Although a PMA is generally a tumor of early childhood and typically occurs in the hypothalamic/chiasmatic region, it can mimic cortical tumors, especially in adults. We report the MR findings of a PMA presenting as a cortical brain tumor in an adult with neurofibromatosis 1 (NF1).

A primary leiomyoma in the neural foramen of the lumbar spine is a very rare condition. We examined a 23-year-old female presented with back and right flank pain. A plain radiography showed a well-defined, osteolytic lesion in the L3 body. In addition, MR images showed a mass lesion with intense enhancement, after intravenous injection with contrast material, in the right neural foramen at the L2/3 level. A histopathologic examination of the resected specimen revealed a benign leiomyoma. 요추골 신경공에 발생한 원발성 평활근종은 매우 드문 질환이다. 저자들은 요통과 측복부 통증을 주소로 내원한 23세 여자환자를 검사하였다. 단순촬영에서 경계가 분명한 골용해성의 병변이 제3요추에서 관찰되었다. 자기공명영상검사에서 강한 조영증강을 보이는 종괴가 제2요추와 제3요추 사이의 우측 신경공에서 관찰되었다. 조직병리학적 검사에서 검체는 양성 평활근종으로 확인되었다.
