| Popis: | A 21-year-old male presented with a pineal dermoid cyst manifesting as headache and diplopia. He had undergone gross total removal of a pineal mature teratoma 18 years before and had done well until recently. Diffusion-weighted magnetic resonance imaging showed a region of high signal intensity due to a round mass in the pineal region and extending into the trigone of the right lateral ventricle. Subtotal excision of the tumor was achieved. Histological examination showed an epidermoid cyst consisting of keratinized stratified squamous epithelium and connective tissue. Intraoperative observation had detected black hairs, so the diagnosis was dermoid cyst. The dermoid cyst may have arisen from a microscopic remnant of the cyst wall of the original pineal mature teratoma. The regrowth of a dermoid cyst 18 years after gross total removal of a mature cystic teratoma in the pineal region is exceptional. However, careful follow-up of patients who undergo gross total removal of a pineal teratoma is recommended for a period more than that of the patient's age at surgery plus 9 months. |
