中文摘要 | 間質軟骨肉瘤一種罕見的軟骨惡性腫瘤,而發生於薦骨的間質軟骨肉瘤更是罕見。我們報告一個十七歲的年輕男性病例,因為逐漸惡化的下背痛和坐骨神經痛來求診,電腦斷層和磁振造影呈現一個薦骨腫瘤,經由電腦斷層導引下組織切片及開刀後,確立最後病理診斷為間質軟骨肉瘤。然而這個病人的影像並未呈現典型的間質軟骨肉瘤鈣化現像。我們將對於他的臨床表現和影像做一個簡短的討論。 |
英文摘要 | Mesenchymal chondrosarcoma is a rare malignant tumor. It may exhibit as a skeletal or extraskeletal tumor and usually contains calcified deposits. A lesion arising from sacrum is extremely rare. We present a 17-year-old male patient with clinical manifestations of lower back pain and sciatica. Computed tomography and magnetic resonance images of the patient depicted a poorly demarcated sacral tumor with a large extraosseous soft tissue component, but without calcification. Multiple small foci of lung, bone, and lymph node metastases were also found on staging CT images. CT guided biopsy and lumbosacral laminectomy (L5-S3) with partial removal of extradural mass for decompression were performed. The histopathological diagnosis was mesenchymal chondrosarcoma. However, the tumor had poor response to adjuvant chemotherapy and radiation therapy during an 8-month follow-up. |
