Dermoid cysts are epithelial-lined cavities with skin adnexae in the capsule. Only 7% is present in the head and neck. Between 2004 and 2013, four patients with a lingual dermoid cyst underwent a microsurgical carbon dioxide laser resection via a median sagittal glossotomy approach. This approach is an elegant technique combining superior visualization, hemostasis, and little postoperative edem...

Intracranial dermoid cysts are ectodermal lesions of embryological origin. They are of slow progression and symptoms associated with unruptured cysts are most commonly due to mass effect. However, a potential rupture in the ventricular system is rare and can cause meningitis, seizures and hydrocephalus. Hereby, we report a case of a 12-year-old boy presenting with obstructive hydrocephalus due ...

Intradural dermoids are rare congenital tumors representing approximately 0.05% of all intracranial lesions. These benign tumors have a typical appearance on CT and MR due to their lipid components. The complication caused by rupture are the spillage of the fatty material into the cerebrospinal fluid. We report a case of a ruptured dermoid cyst showing fat/fluid levels in both side ventricles a...

was applied to his neck by a kabiraj, and during the next six weeks he tried various drugs without effect. At the end of two months he left his home and went to the Sambalpur hospital, where the swelling on his neck was thrice tapped by the Civil Surgeon. On each occasion a milkwhite fluid was drawn off, and rapidly accumulated again in the course of a few days. After a month at Sambulpur he ca...

There are many kinds of extra-axial brain tumors and tumor-like lesions, and definitive diagnosis is complicated in some cases. In this pictorial essay, we present rare and challenging extra-axial brain lesions including neuroenteric cyst, primary leptomeningeal melanomatosis, isolated dural neurosarcoidosis, intradiploic epidermoid cyst, ruptured dermoid cyst, intraventricular cavernoma, and c...

Nasal dermoids are rare congenital anomalies, which usually present in early childhood as a midline nasal mass that requires surgical management. It is important to rule out any intracranial extension before subjecting the patient to surgery. We describe a case of nasal dermoid with intracranial extension. The embryology of the formation of the nasal dermoid, cyst and sinus, with the role of CT...

Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol) droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond ...

Benign cystic teratoma (dermoid cyst) was managed laparoscopically in 25 cases (16 cyst excisions and 9 oophorectomies). Surgical procedures to avoid spill during ovarian cystectomy and oophorectomy were developed (14 cases). This series demonstrates a gradual evolution in surgical technique. Surgical outcome was good in all cases, complications were rare, and the procedure required a hospital ...
