Differential diagnosis of scalp trichilemmal cyst on MRI

Dermatology. 1996;193(3):263-5. doi: 10.1159/000246262.

Abstract

The characteristic MRI of scalp trichilemmal cysts is reported. The feature of an iso-intense area on T1-weighted images is unique to trichilemmal cysts. MRI is helpful in diagnosing the trichilemmal cyst and useful in distinguishing cystic tumors on the median scalp from a cranial malformation, meningo- or encephalocele.
