[Intrasellar arachnoid cyst. A case report and review of the literature].

Intrasellar arachnoid cyst (IAC) is a very rare pathological lesion occurring in 5 of 1000 autopsy cases, and constitutes 9% of all arachnoid cysts. As a space-occupying mass, IAC may cause headaches, visual disturbances, hypopituitarism, precocious puberty, and the "bobble-head doll" syndrome. The pathogenesis of IAC remains controversial.

[Reconstruction of the sellar floor in transsphenoidal surgery: our experience of 818 patients].

Background And Purpose: Transsphenoidal microsurgery (TSS) is the method of choice for resection of most pituitary tumors. Postoperative cerebrospinal fluid rhinorrhea is one of the most frequent complications of TSS. Its incidence ranges from 1.

[Transsphenoidal surgery of secretory and invasive pituitary adenomas (somatotropinoma or corticotropinoma)--own experiences].

Unlabelled: Invasive pituitary adenomas with extension to the cavernous sinus are rare and comprise 6-10% of all pituitary tumors. Their effective surgical treatment is very difficult. Cavernous sinus invasion increases the morbidity and mortality associated with surgical procedures.

[Transsphenoidal surgery of intrasellar and perichiasmatic tumors--personal experience].

Microsurgical transsphenoidal approach has been for decades an established standard surgical treatment of pituitary adenomas. Actually it offers a safe and rapid midline access to the sellar region with a minimal risk of injury to vascular vessels, the optic chiasm or nerves and the brain. Major limitations of this approach are due to the narrow and deep operating field, with the related possible complications of the pituitary insufficiency and the cerebrospinal fluid rhinorrhea.

[Posttraumatic visual agnosia and epilepsy as a consequence of gunshot injury to the head. Case report].

Half million people in the world, each year have a gunshot injury to the head and eighty thousand of them are hospitalized. Gunshot injuries to the head have became in Poland second most frequent cause of death from head trauma, and in some countries during peace became the most frequent cause of death among patient with head injury. Glasgow Coma Scale (GCS) is a useful prognostic factor for patients with gunshot injury to the head.

[A case of intrasellar craniopharyngioma with the symptoms of pituitary apoplexy].

Craniopharyngiomas account approximately for 2.5% of all intracranial neoplasms. They statistically most often arise in Japanese people (8%) and in children (9%).

[A case of primary abscess of the pituitary gland].

This report details the management of a patient with a primary pituitary abscess with secondary amenorrhea, mimicking pituitary adenoma. The preoperative diagnosis of intra- and suprasellar pituitary abscess was established by X-ray examination of the skull, CT-scans and anamnesis. After transsphenoidal removal of the abscess with accompanying antibiotic therapy the patient had a progressive and nearly complete recovery with normalization of menstruation.

[Anterior transposition of the ulnar nerve in the cubital area-- a contribution to the treatment of reflex sympathetic dystrophy].

A variety of symptoms makes difficult the diagnosis and causes therapeutic problems after blunt limb trauma, particularly after long time from the immediate treatment. Three cases of sympathetic reflex dystrophy of the ulnar nerve as a late consequence of blunt upper limb traumas are presented. Long-term medical and surgical treatment produced temporary remission only.

[Radioisotope cisternography in the diagnosis of subarachnoid cysts].

Two cases of subarachnoid cysts are presented. Radioisotope cisternography proved successful in the diagnosis of this disorder. CT-scan and surgery confirmed diagnostic value of the radioisotope cisternography.
