Epidermoid cyst: highlights on diagnosis and magnetic resonance imaging features

Abstract: Purpose: Epidermoid and dermoid cysts are extremely rare developmental cysts of a benign nature, which may occur anywhere in the body, although about 7% are found in the head and neck. This article reports a clinical case of a patient who had an epidermoid cyst and its magnetic resonance imaging (MRI) features.Case report: This case discusses an epidermoid cyst in a 36-year-old woman complaining about speech difficulty. Clinical examination revealed an extensive swelling on the floor of the mouth. MRI findings… Show more

“…On MRI, epidermoid cysts appear hypointense on T1-weighted images and hyperintense on T2-weighted images due to increased keratin content, whereas the dermoid cyst appears hyperintense on both T1-weighted and T2-weighted images due to increased lipid content 8. In USG, the dermoid cyst may give a ‘bag of marbles’ appearance depending on the consistency of the contents 9…”

“…La etiología de los quistes epidermoides es esencialmente desconocida, se considera que pueden ser congénitos, originándose en cualquier punto de desarrollo del cuerpo, donde el tejido ectodérmico podría verse atrapado en la línea de fusión de los procesos embrionarios. Otro factor causal atribuido es de tipo postraumático, donde se comportan como injerto cutáneo, multiplicándose o produciendo una masa de queratina con crecimiento lento por expansión 16 .…”

“…[4,5] Dermoid and epidermoid cysts of the orbit are described as both superficial and deep formations with most frequently slow intermittent growth. Other than aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also optical nerve compression syndrome.…”
