Background:
Osteochondromas are commonly occurring benign bone tumors which may be either a solitary lesion or occur due to association with hereditary multiple exostoses (HMEs). There have been several reported cases of spinal osteochondromas, but intracranial lesions are rare.

... X-ray of the cervical spine [ Figure 1] showed an exostosis at the posterior aspect of the craniovertebral junction; this finding was confirmed on CT scan [ Figure 2]. e cervical MR showed severe cord compression from the posteriorly located exostosis, and there was a high signal in the cord on the T2-weighted image [ Figure 3]. ...

Osteochondroma is the most common bone tumor representing 20%–50% of all benign bone tumors and 10%–15% of all bone tumors. Osteochondroma has similar radiological appearance in both solitary and multiple forms; the latter is an autosomal dominant disorder termed hereditary multiple exostoses. Associated complications of osteochondroma include defo...

Introduction and importance:
Intracranial osteochondroma is rare, presenting diagnostic challenges due to overlapping imaging findings with other pathologies. This case report highlights the significance of considering osteochondroma in calcified tumour differentials near bone.
Case presentation:
A 34-year-old man with vision deterioration and headaches had an MRI revealing a suprasellar lesion. Intraoperatively, a bony hard tumour was partially resected. Subsequent computed tomography (CT) confirmed a calcified mass contiguous with the posterior clinoid.
Clinical discussion:
Reviewing 28 cases, skull base osteochondromas were common, with differential diagnoses including craniopharyngioma and meningioma. Surgical decision-making involved balancing complete resection for convexity and falx cases versus partial resection for skull base tumours due to proximity to critical structures.
Conclusion:
Intracranial osteochondroma poses diagnostic challenges, especially near bone. Tailored surgical approaches are vital, with complete resection yielding good outcomes for convexity and falx cases. Close follow-up is crucial for monitoring recurrences and complications.
