  4. 4. Dermoid Cysts • Midline Dermoids • CT or MRI before surgery • Intracranial extension is found in approximately 36% of midline dermoids. • Anterior meningocele
  5. 5. Sebaceous (Epidermoid) Cysts • Sebaceous (Epidermoid) Cysts • Synonyms: epidermal cysts and epidermoid cysts • A harmless cyst, especially on the scalp or face, containing the fatty secretion of a sebaceous gland • The term sebaceous cyst is a misnomer as these cysts are not of sebaceous origin. Analysis of the pattern of lipids has shown that they do not originate from the sebaceous glands but from proliferation of epidermal cells within the dermis.1
