Osteom Schädelkalotte

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

Epidemiology

Osteomas are more common in middle-aged men .

Clinical presentation

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

Pathology

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 . They can extend into the paranasal sinuses but do not cross cranial sutures . Most commonly, they occur in the frontal and parietal bones .

Associations

• Gardner syndrome if multiple skull vault osteomas are present

Radiographic features

See main article: Osteoma for further details.

Differential diagnosis

• calcified meningiomas can mimic pedunculated inner table osteomas

Treatment and prognosis

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