Localization of epidermoid cysts to the pineal region is rare. The 7-year-old boy now reported presented with an 18-month history of progressive ataxia. CT and MRI scans demonstrated a 2.5x2.5 cm cyst at the pineal region with obstructive hydrocephalus. At surgery via an occipital transtentorial approach, a characteristic "pearly tumour" was encountered, and complete resection was achieved. We present the management of this child with pineal region epidermoid cyst and review 11 cases reported in the literature since 1968. In all, 8 of the 12 patients were males. The age at the time of diagnosis ranged from 7 years to 69 years. Parinaud's syndrome and hydrocephalus are the most common presenting findings. All but 1 patient underwent direct surgical resection; 1 had stereotactic decompression. Surgical treatment brought about complete resolution of the presenting symptoms and signs in 10 of the 12 cases. One patient had persistent upgaze palsy. One patient died from progression of the pineal region mass. This patient presented with hemiparesis, which is a marker of clinical aggressiveness. The authors advocate direct surgical attack as opposed to stereotactic diagnosis and aspiration to: (1) obtain maximal resection and thereby limit the potential for recurrence and delayed complications of the cyst; (2) possibly avoid shunt placement in patients who present with hydrocephalus; and (3) decrease the likelihood of sampling error.
表皮样囊肿位于松果体区的情况较为罕见。本文报道的一名7岁男孩有18个月进行性共济失调病史。CT和MRI扫描显示松果体区有一个2.5×2.5 cm的囊肿,并伴有梗阻性脑积水。通过枕下经小脑幕入路进行手术时,发现了一个典型的“珍珠瘤”,并实现了完整切除。我们介绍了这名患有松果体区表皮样囊肿患儿的治疗情况,并回顾了自1968年以来文献报道的11例病例。12例患者中共有8例为男性。诊断时的年龄范围为7岁至69岁。帕里诺德综合征和脑积水是最常见的临床表现。12例患者中除1例接受立体定向减压外,其余均接受了直接手术切除。手术治疗使12例中的l0例患者的症状和体征完全缓解。1例患者持续存在上视麻痹。1例患者死于松果体区肿块进展。该患者出现偏瘫,这是临床侵袭性的一个标志。作者主张采用直接手术,而不是立体定向诊断和抽吸,理由如下:(1)实现最大程度的切除,从而限制囊肿复发和延迟并发症的可能性;(2)对于出现脑积水的患者,有可能避免放置分流管;(3)降低抽样误差的可能性。
