A 14-month-old boy underwent suboccipital craniotomy for cerebellar tumour. Magnetic resonance screening of the spine a day after the craniotomy revealed striking spinal subdural enhancement in the thoraco-lumbar region. The differential diagnosis included subacute subdural haematoma (in view of the recent operation) versus spinal metastases (in a view of the marked enhancement). The enhancement resolved spontaneously within 1 month of the operation. Thus, striking enhancement can occur in patients with subdural haematoma and should not be misinterpreted as a disastrous advanced metastatic disease.

一名14個月大的男孩因小腦腫瘤而接受枕骨下開顱術。術後一天的磁共振成像掃描顯示胸腰段椎管 硬膜下有明顯造影強化。鑒別診斷包括亞急性硬膜下血腫(由於病人剛接受完開顱術)及椎管癌轉 移(由於有明顯的造影強化)。術後一個月內強化自行緩解。由此可見,硬膜下血腫患者有可能出 現明顯造影強化,但不應把它誤作嚴重的癌轉移病。
