Nasopharyngeal involvement by Hodgkin's Disease is rare and may result in deafness, headaches, nasal obstructions and other symptoms. Compression of the pituitary gland with resultant panhypopituitarism has not been reported in nasopharyngeal Hodgkin's Disease. This paper documents a patient in whom Hodgkin's Disease of the nasopharynx eroded the bony sella turcica and compressed the pituitary gland causing anterior pituitary insufficiency. The patient presented with a skull x-ray and history compatible with a pituitary neoplasm. The diagnosis was established only by surgical exploration.

In 12 cases of pituitary apoplexy, a preexisting unsuspected adenoma was found. The initial manifestations were sudden onset of headache (12 patients), signs of meningeal irritation (10) with fever (four), altered consciousness (12), and ophthalmologic disturbances (eight). The diagnosis was retrospective in three cases. Radiologic investigations were always suggestive if carefully considered. The plain skull roentgenograms, in particular, showed an enlarged sella turcica in 11 cases. Three patients had prolactin adenomas, and nine had nonfunctional adenomas. Medical treatment was successful in only three patients; surgery was performed in 10 cases by means of a sublabial transseptal microsurgical approach. Postoperative neurologic complications were serious in two cases. Endocrine insufficiencies were common: eight cases of permanent panhypopituitarism, two cases of pluritropic anterior pituitary dysfunction, and three cases of persistent hyperprolactinemia.

A 40-year-old patient presented with intractable headache, panhypopituitarism and diabetes insipidus 5 months after a severe shock syndrome. The magnetic resonance imaging of the brain confirmed a hemorragic necrosis of the pituitary gland. On follow-up, the patient recovered a normal pituitary function, except for the persistence of a partial ACTH deficiency. The pituitary image also normalized. Pituitary apoplexy is a rare disease of severe prognosis due to its neurological and endocrine consequences. It can now be more easily recognized by the new imaging techniques.

We report detailed data on 10 patients who underwent transsphenoidal microsurgical management of histopathologically confirmed Rathke's cleft cysts. Preoperatively, pituitary dysfunction was present in 90%, headaches in 80%, hyperprolactinemia in 70%, and visual interference in 40%. Computed tomography and magnetic resonance imaging had 90% and 100% sensitivity, respectively, in disclosing the lesion. The mean follow-up duration was 22 months. There was no mortality. The only morbidity was sustained diabetes insipidus in one case. Resolution or improvement in preoperative dysfunction occurred in the majority of patients: headaches in 100%, visual deficits in 75%, normalization of hyperprolactinemia in 83%, and reversal of panhypopituitarism in 33%. We conclude that Rathke's cleft cysts can be managed safely and effectively with transsphenoidal drainage and partial excision of the wall.

Incompletely and even adequately clipped berry aneurysms are often reinforced with finely shredded gauze. In seven female patients this practice led to a series of events including headache, pyrexia, seizures, cranial nerve deficits, endocrinopathy, cerebrospinal fluid pleocytosis, and an enhancing mass demonstrated by computerized tomography at the aneurysm site. One patient with blindness, hydrocephalus, and panhypopituitarism died and was examined at autopsy. Three additional female patients have been identified in the literature with similar case histories. It is suggested that in these patients the gauze induced a foreign-body granuloma, accompanied by progressive occlusion of neighboring small arteries. It would seem prudent to reserve gauze reinforcement for aneurysms that cannot be securely obliterated surgically.

A 37-year-old man presented with headache and reduced libido. He suffered from panhypopituitarism, and the walls of the pituitary fossa were noted to be thickened, sclerotic, and irregular. Computed tomography scans showed an intrasellar and suprasellar, patchy enhancing tumor. From a biopsy taken at transsphenoidal surgery, a giant cell granuloma was diagnosed, for which there was no obvious cause. Inflammatory disease within the pituitary fossa should be suspected if a reaction is seen in the surrounding bone.

The authors report a rare case of a 10-year-old girl with craniopharyngioma which showed malignant change after the first operation and irradiation. In June 1981, the patient complained of headache, nausea and vomiting. CT revealed obstructive hydrocephalus due to the calcified mass lesion which extended to the third ventricle. In order to alleviate the high intracranial pressure, the right ventriculo-peritoneal shunt was first settled and after that, partial removal of the tumor was performed. The pathological diagnosis of the specimen was typical adamantinomatous type of craniopharyngioma without any findings of malignancy. After this operation irradiation was performed. The tumor almost disappeared and the patient was discharged from the hospital and went to school, showing some signs of panhypopituitarism. In May 1984, she complained of decreased left visual acuity, right temporal anopsia, headache, nausea and vomiting. CT revealed recurrence of the tumor which obstract the foramen of Monro bilaterally. As an emergency measure, the left ventriculo-peritoneal shunt was added and the state of the patient became recovered. In order to improve decreased visual acuity, the tumor located around the optic nerves and over the frontal base was removed in June 1984, resulting in partial improvement of visual acuity bilaterally. The pathological examination of the second specimen showed, in addition to the part of adamantinomatous type of craniopharyngioma which was the same as before, the existence of thick layer of stratified large atypical cells which partially covered the cyst wall and partially invaded into the surrounding tissues. The pathological diagnosis was poorly differentiated squamous cell carcinoma with craniopharyngioma of 'adamantinoma' type.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors described a case of primary intracranial endodermal sinus tumor (EST), and presented a review of 24 reported cases. From the middle of December 1981, this 15-year-old boy experienced progressive diplopia. At the other hospital, partial removal of the intrasellar tumor was performed by a left frontotemporal craniotomy approximately 2 months after the onset of symptoms. The histological diagnosis was suspected to be a pituitary adenoma, and thereafter, 60Co irradiation was carried out for about a month. On June 5th. 1982, the patient was admitted to the Kochi Medical School Hospital, because of increasing headache with diplopia, hoarseness, dysphagia and limitation of tongue movement. On admission, he had a small stature for his age with moderate diabetes insipidus. Neurological examination showed left abducens, glossopharyngeal and vagal nerve palsies in addition to bitemporal hemianopsia. CT scans revealed a heterogenously enhanced high density mass lesion behind the dorsum sellae with an extension from the upper clivus to the sphenoid sinus. Cerebral angiograms showed posterior displacement of the basilar artery. In the endocrinological examination, panhypopituitarism was recognized with a high level of serum alfa-fetoprotein (AFP). While, serum carcinoembryonic antigen (CEA) and human chorionic gonadotropin (HCG) were in normal range. On July 1st. 1982, a left suboccipital craniectomy was performed. The tumor existed mainly in the extradural space along the clivus, and only a small intradural portion of the tumor was excited.(ABSTRACT TRUNCATED AT 250 WORDS)

Two unusual cases of symptomatic Rathke's cleft cysts are described. The first patient was a 47-year-old man who presented with recurrent aseptic meningitis in addition to visual symptoms, panhypopituitarism, and hydrocephalus. The second patient was a 41-year-old man presenting with increasing headache, and a large, nonenhancing sellar cyst showing suprasellar extension on computerized tomography. The similarities between Rathke's cleft cysts and craniopharyngiomas are discussed.

Intrasellar arachnoid cyst is very rare. We report a case of intrasellar arachnoid cyst. A 44-year-old male was admitted for evaluation of his headache and visual disturbance on August 6, 1993. Neurological examination revealed bilateral decreased visual acuity and visual field defect. Endocrinological examination showed panhypopituitarism. Other neurological findings were normal. X-ray film of the skull showed a ballooning dilation of the sella turcica with thinning of the sellar floor. CT scan showed a cystic lesion with CSF-density occupied the sella. After intravenous administration of contrast medium, the cyst showed no enhancement. MRI showed the intrasellar mass had the same characteristics as the surrounding subarachnoid space. Bilateral carotid angiographies demonstrated that the carotid siphons were stretched and displaced laterally, and the A1 portions of the anterior cerebral arteries were raised. We made a diagnosis of intrasellar cystic lesion. On August 18, the sella turcica was opened via the transsphenoidal rhinoseptal approach. The cyst contained CSF-like fluid, and a part of the cyst wall was resected. The cavity was filled with Gelfoam and the sellar floor was repaired with bone flap. Postoperatively, the patient's visual disturbance improved, but diabetis insipidus appeared and required hormonal replacement. The patient was discharged on September 27 with improvement of visual acuity and visual field. Histological examination demonstrated that the cyst wall consisted of thick arachnoidal cells with fibrous connective tissue. The arachnoidal cells with oval nuclei was stained with epithelial membrane antigen. Symptoms, signs and radiological findings of intrasellar arachnoid cyst are similar to those of various sellar lesions including pituitary adenoma, craniopharyngioma, empty sella, Rathke's cleft cyst, epidermoid et al.(ABSTRACT TRUNCATED AT 250 WORDS)
