Chondroblastoma is a rare, benign bone tumor originating from immature chondrocytes, typically found in the epiphyseal plates of long bones. Its occurrence in the skull, particularly the occipital bone, is extremely rare.
We report a 10-year-old girl presenting with paroxysmal dizziness, occipital pain, and a palpable mass. Imaging studies revealed an osteolytic lesion in the occipital bone with a multiloculated appearance, indicating a concomitant aneurysmal bone cyst. The patient underwent craniotomy with complete tumor excision. Postoperative follow-up showed no neurological deficits or complications and MRI confirmed no recurrence.
This case highlights the rare presentation of occipital bone chondroblastoma and emphasizes the importance of early surgical intervention for positive outcomes in pediatric patients.
成软骨细胞瘤是一种罕见的良性骨肿瘤，起源于未成熟的软骨细胞，通常发生在长骨的骺板。其在颅骨，特别是枕骨中发生极为罕见。
我们报告了一例 10 岁女孩，表现为阵发性头晕、枕部疼痛和可触及的肿块。影像学研究显示枕骨有溶骨性病变，呈多房性，提示同时存在动脉瘤样骨囊肿。患者接受了颅骨切除术，行肿瘤完全切除。术后随访无神经功能缺损或并发症，MRI 证实无复发。
本例提示了枕骨成软骨细胞瘤的罕见表现，并强调了在儿科患者中早期手术干预对于获得良好结果的重要性。
