Presentation
Incidental finding. The patient presented with uncontrolled hypertension and headache.
Patient Data
There are bilateral, somewhat symmetric, scattered, multifocal, punctate, cutaneous, calcific densities within the frontal scalp and malar regions.
Bilateral choroid plexus xanthogranulomata.
Non-contrast CT brain is otherwise unremarkable, specifically, there are no subarachnoid hemorrhages, no surface collections, and no intracerebral hemorrhages.
Case Discussion
Facial and scalp calcified nodules encountered in routine head and facial CT imaging are common, benign, age-related findings and represent a manifestation of primary benign miliary osteoma cutis 1.
Osteoma cutis refers to the formation of bone within the skin 1.
The differential diagnosis is calcinosis cutis, which refers to the deposition of amorphous calcium salts within the skin 1.
Both conditions may be differentiated radiologically and/or histopathologically 1.
