Background:
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.
Case Presentation:
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.
Conclusion:
This case highlights the rare presentation of occipital bone chondroblastoma and emphasizes the importance of early surgical intervention for positive outcomes in pediatric patients.

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
