Various lesions can affect the vault of the skull, usually asymptomatic and of incidental discovery, but can also present as a swelling with or without local pain. We report a retrospective study of 20 cases collected in the neurosurgery department at HMPIT over a 17-year period from January 1, 2000 to December 31, 2016.The mean age was 47.7 years, with extremes ranging from 20 to 75 years, with a slight male predominance and a sex ratio of 1.2.An incidental finding of an arch lesion was found in 3 cases.Frontal location was the most common, accounting for 45% of cases, followed by parietal location (35%).Histological examination of the surgical specimen was carried out in all our patients, confirming our suspicion of a diagnosis.Secondary localization was common in 9 cases, with breast cancer in 2 and thyroid cancer in 2.Most of these patients reported clinical improvement following surgery or radiotherapy, and the prognosis for tumors of the vault will depend on the etiology.
