Pineal region tumors are commonly present in the pediatric age group. However, pleomorphic xanthoastrocytoma (PXA) is very rare at this region, and only few case reports have been reported till now in literature. Here, we report a rare case of pineal region, juxta-thalamic, pleomorphic xanthoastrocytoma (PXA) in an 11-year-old male child. The child presented with severe headache after which MRI was done. It was suggestive of pineal region low-grade tumor. The patient was operated in Parkbench position with SCIT (supracerebellar approach) in a retractor-free manner. Gross total resection was done. However, the patient developed postoperative left-sided hemiparesis. It got improved in 1 month, and the patient became ambulatory. Histopathology came out as pleomorphic xanthoastrocytoma. Surgical management should include careful resection near the internal capsule to avoid postoperative hemiparesis. Also, shunt should be delayed in the cystic cavity created by resection of tumor.

松果体区多形性黄色星形细胞瘤：成功手术治疗的罕见病例报告

松果体区肿瘤常见于儿科年龄组。然而，多形性黄色星形细胞瘤（PXA）在该地区非常罕见，迄今为止文献报道的病例报告很少。在这里，我们报告了一例罕见的松果体区、丘脑旁、多形性黄色星形细胞瘤 (PXA) 病例，该病例是一名 11 岁男孩。孩子出现了严重的头痛，之后做了 MRI。提示松果体区低度肿瘤。患者在 Parkbench 位置使用 SCIT（小脑上入路）以无牵开器的方式进行手术。进行了大体切除术。然而，患者术后出现左侧偏瘫。1个月内好转，患者可以走动。组织病理学结果为多形性黄色星形细胞瘤。手术治疗应包括仔细切除内囊附近以避免术后偏瘫。此外，在切除肿瘤后形成的囊腔内应延迟分流。
