RESUMO

OBJECTIVE: The authors report the clinical, radiological, and surgicalfindings ofpatients with craniocervical junction tumors surgically treated in the institution over the last 8 years. MATERIAL AND METHOD: A retrospective study was performed. Clinical, radiological, and operative data were evaluated, and follow-up information was obtained from outpatient examinations, and telephone interviews. RESULTS: There were 25 patients consisting of nine chordomas, eight meningiomas, three cysts, two schwannomas, one each of aneurysmal bone cyst, plasmacytoma, and metastasis. Twenty-nine operative procedures were performed, classified as 12 anterior nine posterior-lateral, and eight posterior approaches. Gross total removal was achieved in 17 cases, subtotal removal in six cases, and partial removal in two cases. Re-operation was performed in six cases. Median follow-up time was 31 months. The authors found significant improvement in Karnofsky Performance Scale scores. CONCLUSION: Appropriate surgical approaches provide successful tumor removal with less surgical morbidities, nevertheless recurrent tumors occasionally occur and so, long-term follow-up is mandatory.

RESUMO

A 45-year-old man presented with progressive deterioration of vision. Visual acuity test revealed no light perception in both eyes. The fundoscopic examination demonstrated pale optic discs, consistent with secondary optic atrophy. Preoperative neuroimaging studies revealed a well-defined contrast-enhancing mass, 3 cm in diameter, at the left parietal region. Its radiologic appearances simulated those of cerebral metastases. A totally removed lesion was verified pathologically as an anaplastic clear cell ependymoma, which is rare in this location. A brief review of clinical features and neuroimaging of supratentorial lobar ependymoma is also included.
