A case of suprasellar tumor associated with so-called atypical angina pectoris was reported. A 58-year-old man was admitted to our hospital on Feb. 2, 1973, because of headache, disturbance of visual field and the attack of chest pain. He had been suffering from disturbance of visual field for about 3 years and the attack of chest pain for about 4 months prior to admission. Neurological findings on admission were bitemporal hemianopia, decreased visual acuity and atrophy of the optic disc. Bilateral carotid angiography showed upward displacement of A1 portion of the anterior cerebral artery. Pneumoencephalography demonstrated defect of the anterior part of the third ventricle. Laboratory examination showed hypopituitalism. On March 26, 1973, Right frontal craniotomy was performed under the diagnosis of suprasellar tumor. The walnut-sized tumor was detected in the suprasellar region and removed totally. Histological examination showed dermoid cyst. With regard to the attack of chest pain, the selective coronary angiography was performed. But organic change was not detected and Master's two step test did not induce any pathological finding in EEG. So we made a diagnosis of so-called atypical angina pectoris. There are many arguments about pathogenesis of so-called atypical angina pectoris. There is no organic change of the heart of attention now. Recently it is said that so-called atypical angina pectoris is closely connected with paradoxical sleep. We recognized dysunction of the autonomic nervous system through various examinations. The hypothalamus was displaced upward by a suprasellar tumor in this case. After removal of the suprasellar tumor, the frequency of the attack of chest pain was decreased. The atypical angina pectoris in the presented case may be considered to consequence of distrubance of the hypothalamic function.

Primary malignant melanoma of the cerebral nervous system is an uncommon entity. A case of primary intracranial melanoma associated with dermoid cyst is reported. The patient was a 40-year-old man who was admitted to our hospital on May 2, 1979 complaining of headache, double vision, left hemiparesis and Jacksonian seizure. On admission he had a slight degree of papilledema. Left abdominal reflex was absent. Lumbar puncture showed high pressure of the cerebrospinal fluid which was otherwise normal. Plain skull films showed a calcification in the pineal region. CT scan demonstrated multiple high density areas with slight enhancement after contrast medium infusion in the right fronto-parietal region and a well defined high density area associated with an irregular low density area without contrast enhancement in the right pulvinar and the atrium and temporal horn of the right lateral ventricle. However, no tumor stain was seen on angiograms. On May 8, 1979 partial removal of the tumor was performed. Areas of black discoloration were seen in the leptomeninges of the right fronto-parietal lobes. Histopathological examination of this tumor revealed primary intracranial melanoma. Postoperatively DTIC, ACNU and Vincristine were administered intravenously but the tumor showed only little sensitivity. He died 5 months after operation. Autopsy was performed on October 8, 1979. Malignant melanoma in the right fronto-parietal lobes was invading the cerebellar hemisphere and spinal cord, but any tumor was not found in any other parts of the body except for this central nervous system. The tumor in the right pulvinar extending to the atrium and temporal horn of the right lateral ventricle was a dermoid cyst with calcification histopathologically. A case of primary intracranial melanoma associated with dermoid cyst has not been reported in any other associated with dermoid cyst has not been reported in any other literature yet.

Dermoid cysts in the central nervous system are often associated with various congenital disorders, especially dermal sinus and spina bifida. We report a case of dermoid cyst in the fourth ventricle associated with Klippel-Feil syndrome. A 47-year-old man with a long history of headache had been known to have a cystic lesion in the posterior fossa for 12 years. When he was referred to our hospital with complaints of transient tetraparesis, he showed bilateral cerebellar ataxia and minimal left hemiparesis. Furthermore, he was noted to have a webbed neck with a low hairline and facial asymmetry. CT and MRI showed multiple cerebral infarctions as well as a mass lesion in the posterior fossa. Cervical roentgenogram showed a fusion of C 2 and C 3 vertebrae. The tumor was totally removed via a suboccipital approach, and the diagnosis was a dermoid cyst. The present patient had not only dermoid cyst and Klippel-Feil syndrome but also hypertrophy of the zygomatic bone. The pathogenesis of the Klippel-Feil syndrome is presumed to be an intrauterine defect, with a failure of segmentation of mesodermal somites. The zygomatic bone is also derived from the mesoderm somites at early fourth week, too. From these points of view, the disturbance in the mesoderm before the fourth week of gestation might have played an important role in causing a dermoid cyst.

We report a man with a ruptured intracranial dermoid cyst, suffering from headache, nausea, vomiting and a generalised seizure. MRI was performed before and 2 weeks after surgical resection. On T1-weighted images the tumour gave high signal, as did fatty material in the frontal and parietal brain sulci. Identification of this hyper-intense material as lipids was possible by chemical-shift-selective 3D gradient-echo imaging, which provided excellent contrast between the subarachnoid lipids and the adjacent normal brain, with a good spatial resolution. Possible complications of subarachnoid and intraventricular lipid particles after dermoid cyst rupture are discussed and the diagnostic value of 3 D chemical-shift-selective additional to conventional T-1-weighted spin-echo images in identification of even small amounts of fat is emphasised.

This case shows an unusual intracranial cause of chronic headache in a 30-year-old female. Computerized tomography and magnetic resonance imaging were used to demonstrate an intracranial, dermoid cyst located in the left middle cranial fossa. Droplets of fat-like material, which leaked from this cyst, were present in the basilar subarachnoid spaces and left sylvian fissure. Since the surgical excision of the cyst, the patient has not had any severe headaches.

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.

A 47-year-old male presented with headache. Magnetic resonance imaging revealed an enhanced mass lesion in the cerebellar vermis and left cerebellar hemisphere and in the cisterna magna. Gross total removal of the tumor was performed. Histological examination demonstrated squamous cell carcinoma in the dermoid cyst. The patient subsequently received localized radiation therapy of total 55 Gy. He has been without tumor recurrence for 6 years since the surgery. We recommend local radiation therapy over 50 Gy following surgery.

Primary benign cystic lesions in the brain are uncommon. However, extracerebral cysts like arachnoid cyst, epidermoid cyst and craniopharyngiomas are fairly common lesions. Also, colloid cyst in the third ventricle, dermoid cyst and endodermal cyst in the extracerebral location are not uncommon. On the contrary, intraventricular ependymal and choroidal cysts in the intraventricular location are infrequent. Surgical intervention is warranted in cysts, which produce a mass effect and raised intracranial pressure. We present an interesting case of a giant intraventricular ependymal cyst in the temporal horn in a 14-year-old boy, who presented with recent onset of headaches and epilepsy. He also had long-standing progressive proptosis of the left eye and left temporal bossing. Excision of this cystic lesion was curative. Interesting clinical and neuroimaging features are presented.

A 22-year-old woman was admitted to our department after developing a headache. The neurological findings were unremarkable on her first visit, but CT demonstrated a lot of low-density masses in the subarachnoid space. The largest mass was in the right sylvian fissure. These lesions appeared hyper-intense in T1, T2 and diffusion-weighted MR images. A right frontotemporal craniotomy was performed to remove the main mass lesion in the right sylvian fissure. During surgery, thickening of the arachnoid membrane and floating oily globules were seen in the subarachnoid space. The histopathological examination revealed that the tumor was a dermoid cyst. Follow-up MRI revealed that some of the small lesions had moved since the operation. These findings suggested that the tumor was a ruptured dermoid cyst. The patient's postoperative course was uneventful and her headache disappeared completely.

We report a case of a dermoid cyst in the parasellar area associated with porencephaly. A 22-year-old man presented with headache and visual disturbance. Non-enhanced brain CT showed a high density mass in the parasellar area and a low density area in the left temporal lobe. On gadolinium-enhanced T1-weighted images, a partial rim enhancement was present in the parasellar region. A presumptive diagnosis of Rathke cleft cyst, craniopharyngioma, non-function pituitary adenoma, or germ cell tumor was considered. A left frontotemporal craniotomy was performed and the tumor was removed almost totally. The tumor was well-capsulated and contained whitish, milky debris. The histologic diagnosis was dermoid cyst. The temporal lobe lesion was porencephaly. The postoperative course was uneventful. Their most typical aspect is the presence of a low-density mass on CT, allowing an easy radiologic diagnosis of dermoid cyst containing lipids. Enhancement following contrast administration is uncommon. The hyperdensity may be related to the high protein content of the lesion. The hyperdense aspect of the lesion on CT, and the presence of rim enhancement made the radiologic diagnosis of a dermoid cyst difficult in this case. A case of dermoid cyst associated with porencephaly has not yet been reported in the literature.
