“…Other problems that can occur include bone resorption near the intradiploic epidermoid cyst due to middle ear cavity or cholesteatoma infection, interleukin-1, fibroblast production, collagenase, and granulocyte-macrophage colony-stimulating factor secretion, etc [2] . Complications of intradiploic epidermoid cyst are abscess formation, hemorrhage, and malignant change, etc [1,3,6,13] . There are more risks of malignant changes with recurrent operations or repetitive intracystic infections [1] .…”

Intradiploic epidermoid cyst of the skull, despite being rare and representing less than 1% of all intracranial tumors, is a benign lesion that is derived from an ectodermal cell rest within the cranium. The frontal and parietal bones are the most common sites for the cyst; however, the temporal bone, although rarely, is also involved. Intradiploic epidermoid cysts have slow growth rates and often grow to enormous sizes without producing any measurable neurological symptoms. For treatment, a complete removal of the cyst with its capsule is important to avoid recurrence. Very rare malignant transformations of the cysts have been reported, generally in cases with repeated recurrences or infections. A 16-year-old female patient was diagnosed with a temporal bone intradiploic epidermoid cyst behind the left mastoid cavity, which was successfully removed through a transmastoid approach.

“…Although the cranium is the most common site of the cysts, cases of intradiploic epidermoid cysts occurring in the temporal bone have also been reported [1] . The occurrence of intradiploic epidermoid cysts in the temporal bone is extremely low; there are currently only 20 global [2][3][4][5][6] . and two Korean cases reported [7,8] .…”

Intradiploic epidermoid cyst is a benign lesion that is derived from the ectodermal cells of the cranium. It is a rare tumor, representing less than 1% of all primary intracranial tumors. It can be located in any part of the skull, but frontal and parietal bones are the most common sites for the cysts. It occurs from the first to the seventh decade of life. Because it is a slowly growing tumor, it is usually discovered incidentally and may remain asymptomatic for many years. Rarely, it grows intracranially to produce brain compression or undergo malignant change. For treatment, it is important to completely remove the capsule of the cysts to avoid recurrence. I describe a 25-year-old man with an intradiploic epidermoid cyst of the temporal bone, who underwent tumor removal and simple mastoidectomy. I also describe the unique radiologic findings of my case, which differed from those of cholesteatoma.
