A Rare Case of Occipital Region Bony Calvarial Primary Osteosarcoma

Rationale: Primary osteosarcoma of calvarium is considered one of the rarest neoplasm of skull and accounts for 1 to 3% of all skull neoplasms. It is an aggressive bone neoplasm and is characterized by presence of spindle cell leading to a generally poor prognosis. Case report: A female patient aged appox 55-years came to our neurosurgery outpatient department having complain of progressively enlarging mass in occipital region of her skull. MRI revealed a lytic, expansile soft tissue lesion involving the occipital bone which was excised surgically and tissue was sent for histopathology which confirmed the final outcome as osteosarcoma of skull. Decompression surgery was done to alleviate symptoms. Conclusion: Primary calvarial osteosarcoma is considered as one of the rarest neoplasm of skull, emphasizing need for prompt identification and accurate diagnosis to improve patient outcome. Clinician must be vigilant in recognizing this condition to facilitate timely intervention. A comprehensive treatment approach involving surgical resection followed by chemoradiation has been shown to yield optimal results.
