Seven cases of posterior fossa subdural empyema were treated between 1955 and 1984; 3 of the patients survived. The two sources of infection were otogenic and spread from supratentorial subdural empyema complicating acute frontal sinusitis. Investigations including computerized axial tomography (CT) scans were sometimes equivocal and diagnosis was sometimes delayed. Posterior fossa craniectomy appeared to be the operation of choice; all the patients treated only by posterior fossa burr holes died. Early aggressive surgical intervention in such cases should result in a minimal morbidity.
1955年至1984年间共治疗了7例后颅窝硬膜下积脓患者；其中3例患者存活。感染源有两个，一个是耳源性的，另一个是由幕上硬膜下积脓蔓延而来，后者并发急性额窦炎。包括计算机断层扫描（CT）在内的检查结果有时不明确，诊断有时会延迟。后颅窝颅骨切除术似乎是首选的手术方式；所有仅接受后颅窝钻孔治疗的患者均死亡。对于此类病例，早期积极的手术干预应能将发病率降至最低。
