Gardner's syndrome and steatocystoma multiplex. Two unusual genetically determined conditions occurring in same patient.
A 43-year-old man is described who had Gardner's syndrome and steatocystoma multiplex. These two unusual genetically determined conditions were associated because he had inherited the Gardner's syndrome from his father and the steatocystoma multiplex from his mother. (+info)
Contralateral deafness following unilateral suboccipital brain tumor surgery in a patient with large vestibular aqueduct--case report.
A 68-year-old female developed contralateral deafness following extirpation of a left cerebellopontine angle epidermoid cyst. Computed tomography showed that large vestibular aqueduct was present. This unusual complication may have been caused by an abrupt pressure change after cerebrospinal fluid release, which was transmitted through the large vestibular aqueduct and resulted in cochlear damage.

A 50-year-old female presented with primary intracranial squamous cell carcinoma (SCC) at the right cerebellopontine angle manifesting as right facial nerve paresis. She had undergone gross total removal of a right cerebellopontine angle epidermoid cyst 10 years before and had done well until recently. Magnetic resonance imaging showed a heterogeneous tumor with markedly enhanced irregular margin. Subtotal removal of the tumor was achieved. Histological examination showed moderately differentiated SCC. After surgery, she underwent chemotherapy and gamma radiosurgery. She is now well 5 years after the diagnosis of SCC. (+info)
Unusual sonographic appearance of an epidermoid cyst of the testis.
Epidermoid cyst of the testis is a rare benign testicular tumor with varied sonographic appearances. We present a case in which two specific ultrasonographic patterns were seen: (1) an "onion ring" configuration of alternating hyperechoic and hypoechoic regions, described previously as being characteristic of this lesion, and (2) a heterogeneous region with multiple punctate hyperechoic foci.

Epidermoid tumor within Meckel's cave--case report.
A rare case of an epidermoid tumor lying within Meckel's cave is reported. A 27-year-old housewife presented with complaints of right facial hypesthesia for two and a half years. On examination she had partial loss of touch sensation in the right trigeminal nerve distribution. Magnetic resonance imaging revealed a tumor located at the right petrous apex and cavernous sinus. The epidermoid tumor was excised through a lateral basal subtemporal approach. The symptoms resolved following surgery. (+info)
Intramedullary spinal epidermoid cyst.
Intramedullary epidermoid cysts of the spinal cord are rare tumours, especially those not associated with spinal dysraphism. Around 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient the tumour was located at D4 vertebral level, while in other within the conus medullaris. The clinical features, MR imaging characteristics and surgical treatment of such rare intramedullary benign tumours are discussed, and the relevant literature reviewed. (+info)
The utility of diffusion-weighted imaging with navigator-echo technique for the diagnosis of spinal epidermoid cysts.
We report a case of a spinal epidermoid cyst in which diffusion-weighted imaging with a navigator-echo technique was useful for the differential diagnosis from other cystic tumors. Motion artifacts are inherent on diffusion-weighted images of the spinal region; however, the navigator-echo technique compensated for this problem and provided high-quality images. Diffusion-weighted imaging with navigator echoes is considered to be a potentially useful tool in the differential diagnosis of spinal cystic tumors. (+info)
Hyperdense intracranial epidermoid: an uncommon presentation.
A thirty year old female presented with sudden onset of severe headache, papilloedema and altered sensorium. Computerised tomography (CT) scan showed a hyperdense vermian mass in the posterior fossa. Operative findings and histological examination revealed spontaneous bleed into the epidermoid cyst. Difficulty in the preoperative diagnosis and uncommon presentation of the intracranial epidermoid cyst prompted us to report this case. (+info)
