چکیده

Intracranial dermoid cysts with hemorrhage are fairly rare. Herein, we reported a 28-year-old female patient with a cerebellar dermoid cyst, which was found accidently on neuro-imaging after head trauma. MR scanning revealed that the lesion was located within the cerebellar vermis and was measured 3.5cm×3.9cm×3.0cm, with hyper-intensity on T1WI and hypo-intensity on T2WI. However, on CT imaging, it showed hyper-dense signals. It was removed completely via midline sub-occipital approach under surgical microscope. Histological examination proved it was a dermoid cyst with internal hemorrhage. In combination with literature review, we discussed the factors that might be responsible for the hemorrhage within dermoid cysts.

Occipital dermal sinus associated with dermoid cyst in the fourth ventricle.

MR was helpful in demonstrating the spatial relationship between a dermoid cyst in the fourth ventricle and an occipital dermal sinus. T1-weighted images clearly showed the mixed hypointense mass in the fourth ventricle and above the vermis, which appeared to be connected to an occipital dermal dimple.

Occipital dermoid cyst associated with dermal sinus and cerebellar abscesses.

sinus is a rare entity, with fewer than 20 cases reported in the literature1. We describe the unique computed tomogram (CT) and magnetic resonance (MR) imaging findings of an infant presenting with cerebellar abscesses and secondary obstructive hydrocephalus resulting from an occipital dermoid cyst with a complete dermal sinus, confirmed at operation. Early neurosurgical intervention is advocat...

Characteristics of Dermoid Cyst of the Auricle

BACKGROUND Dermoid cysts of the auricular area are extremely rare. We report on six cases of auricular dermoid and epidermoid cyst, and differentiate dermoid cyst from epidermal cyst along with a review of the literature. METHODS Three cases involved a gradually enlarging mass of the superior and anterior aspect of the helix of their ear. Another two cases were located in the posterior aspect...

Oiled Brain and Status Epilepticus: Intraventricular and Subarachnoid Rupture of a Temporal Dermoid Cyst

Intracranial dermoids are rare slow-growing tumors. Generally, they are revealed after they reach a considerable volume, leading to the compression of neural structures. Exceptionally, these inclusion tumors can rupture spontaneously within the subarachnoid, intraventricular or subdural spaces. We present the case of a ruptured temporal dermoid cyst with intraventricular, subarachnoid and subdu...

Traumatic rupture of an intracranial dermoid cyst

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 ...
