Intracranial tumors may rarely cause stroke. We report an epidermoid cyst causing stroke in a pediatric patient. We have also reviewed the literature and pathogenesis of stroke caused by intracranial tumors.

BACKGROUND Spinal epidermoid cysts are benign tumors, which are rarely seen as an intradural extramedullary spinal cord tumor in the conus medullaris region. Acquired spinal epidermoid cysts are mostly caused by iatrogenic procedures, such as lumbar puncture, and the majority of acquired spinal epidermoid cysts have been reported below the L1 level, because lumbar puncture is usually performed ...

A 39-year-old man developed dizziness and diplopia. Examination showed medial gaze palsy of the right eye. He had no headache, vertical gaze palsy, or skew deviation. A CSF examination was not performed. MRI (figure) showed cystic mass and acute infarction. After 7 days heparization, the mass was removed by surgery and pathology confirmed the dermoid cyst. After operation, the neurologic abnorm...

A 58-year-old Japanese man suddenly suffered from vertigo. On physical examination, left-beating horizontal torsional spontaneous nystagmus was observed; the direction did not change with gaze. Other neurotological examinations revealed findings within normal limits except the left side sensorineural hearing loss of approximately 32 dB on average. Diffusion-weighted MRI revealed no infarction i...

The epidermoid cyst is a benign lesion which characteristically consists of a cyst lined by squamous epithelium and contains keratinous debris [1]. With regard to the thyroid gland, it is usually not diagnosed until biopsy is undertaken [2-7]. Therefore, this paper presents 3 cases found by means of the establishment of a histopathology data pool as was recommended by a Birmingham (UK) group [8...
