MATERIAL and METhODS: We retrospectively reviewed 45 consecutive patients operated for calvarial masses from January 2002 till May 2012 at our hospital. Skull base tumors and patients <=18 years were excluded. RESULTS: Three groups of lesions were found - calvarial metastases (15/45), primary tumors (5/45) and tumor-like lesions (25/45). Malignant lesions were equitable by gender distribution, higher age of onset (median age of primary =55; secondary = 60 years) and benign lesions by younger age (median = 35) and female bias (18/25). Calvarial metastases mostly presented with local swelling (10/15), local pain (6/15) and rarely neurologic deficit. There was associated dural sinus thrombosis (4/20 of malignant; 1/25 of benign lesions) and osteolysis (3/5 primary malignant, 13/15 secondary and 18/25 of benign lesions). Complete surgical excision was possible with minimal morbidity in all except one patient and nil mortality. CONCLUSION: Nearly half (20/45) of the calvarial lesions tend to be malignant with most of them presenting as silent painless masses. Surgical excision should be considered only after suitable investigation and appropriate neurosurgical set-up.eninfo:eu-repo/semantics/openAccessCerrahiArticle265690698
