Implantable intrathecal infusion pumps (ITPs) are an effective pain management modality for patients who have failed non-operative options. We present the first report of asymptomatic intracranial subarachnoid fat dissemination secondary to an ITP. A 39-year-old who underwent implantation of an ITP for intractable pelvic pain developed altered mental status. CT and MRI revealed subarachnoid fat deposition without evidence of a dermoid or epidermoid cyst. She returned to her baseline mental status with her symptoms attributed to delirium. The rare possibility of subarachnoid fat dissemination following transdural spinal procedures should be considered as a potential complication of ITPs. Although fat may persist in the subarachnoid space for years, asymptomatic patients can be safely managed with observation alone.
植入式鞘内输注泵（ITP）是对非手术治疗失败的患者有效的疼痛管理方式。我们报告首例因 ITP 导致无症状颅内蛛网膜下腔脂肪播散的病例。一位 39 岁的患者因难治性盆腔疼痛接受了 ITP 植入，术后出现精神状态改变。CT 和 MRI 显示蛛网膜下腔脂肪沉积，无皮样囊肿或表皮样囊肿证据。她的精神状态恢复到基线水平，其症状归因于谵妄。在硬脊膜外脊柱手术后，蛛网膜下腔脂肪播散的罕见可能性应被视为 ITP 的潜在并发症。尽管脂肪可能在蛛网膜下腔中持续存在数年，但无症状患者可通过单纯观察进行安全管理。
