Skull vault osteoma

Dr Francis Deng and Dr Henry Knipe et al.

Skull vault osteomas are benign primary bone lesions that are commonly incidentally discovered. They are less common than paranasal sinus or mandibular osteomas

Osteomas are more common in middle-aged men 1,3.

Skull vault osteomas are typically asymptomatic but may present as painless, slow-growing masses or with compressive symptoms 2,4

Skull vault osteomas are juxtacortical in location and can be sessile or pedunculated and arise from the outer table (most commonly), intradiploic space, or inner table 1. They can extend into the paranasal sinuses but do not cross cranial sutures 1. Most commonly, they occur in the frontal and parietal bones 4

See main article: Osteoma for further details. 

  • calcified meningiomas can mimic pedunculated inner table osteomas 3

No treatment is required if asymptomatic. Symptomatic osteomas are typically surgically excised 4.

Bone tumours

The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient.
