چکیده
Epidermoid cysts are benign. slow-growing. congenital lesions (2. 4. 11). Craniocerebral epidermoid cysts constitute approximately 1% of all cranial tumors (1. 9). Calvarial intradiploic epidermoid cysts are very rare. In 1838. Miller was the first to describe a diploic epidermoid cyst of the skull (2). According to Ciappetta et al.. total 223 cases had been reported up to 1990 (2). Because of the slow expansion of the cyst. neurological deficit is absent or minimal. They are commonly seen as an incidental finding on x-ray examination.

Large Intradiploic Epidermoid Cyst of the Temporal Bone
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 of...

INTRODUCTION Extradural intradiploic epidermoid cysts are rare, representing less than 0.25% of all primary intracranial tumors. They can be neurologically silent and can only present psychiatric symptoms like depression, cognitive or personality changes.

متن کاملAtypical Intracranial Epidermoid Cysts: Rare Anomalies with Unique Radiological Features
Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstra...

INTRODUCTION We report a case of tumor growth over a period of four decades, presenting with large multicentric lytic lesions of the skull and a profound mass effect, without neurological deficits. Clinical and radiological features of a patient with a giant intradiploic epidermoid and its impact on the choice of treatments are discussed.

Epidermoid cysts (ECs) are benign, slow-growing, congenital tumors. Intracranial ECs usually localize in extra-axial spaces, particularly in the cerebellopontine angle or in the parasellar region. Their occurrences in the fourth ventricle or intradiploic location are exceptionally rare. We present the imaging findings in two patients with atypical localization of ECs. Magnetic resonance imaging...
