Aim: Many cases of suprasellar region germinoma occurs in diabetes insipidus (DI), but a patient initially may come to the hospital for the chief complaint of visual impairment. The aim of this study is to determine the etiology of initial symptom presentation and the outcomes of visual impairment and DI in suprasellar region germinoma. Methods: We investigated eleven cases of single lesion sup...

Computed tomography is the method of choice for initial evaluation of pa tints with potential suprasellar masses. In our ex­perience during the last 2 years C.T. has proved reliable for detecting or rulling out the presence of a suprasellar mass.  It shows the direction and degree of parasellar extension and the presence of any calcific or cystic component of the le­sion. When C.T. was negat...

Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We...

Background and Importance: Symptomatic Rathke’s cleft cyst is a rare lesion that often presents without any symptoms.  Case Presentation: We report a 40-year-old female with symptomatic Rathke’s cleft cyst located in the sellar and suprasellar region. She presented with visual disturbance, headache, weight gain, hypothyroidism and amenorrhea. The patient underwent surgery and ...

Surgical Treatment of Suprasellar Arachnoid Cyst Dr. A. Barth, Neurochirurgische Klinik, Inselspital, CH-3010 Bern (Switzerland) Dear Sir, Suprasellar arachnoid cysts often present with hydrocephalus [1, 2]. Even if hydrocephalus can usually be treated without permanent shunting devices, the best surgical approach remains presently controversial concerning the operative risks and the avoidance ...

A 33-year-old male with right eye amaurosis and panhypopituitarism previously submitted to surgery and radiotherapy was admitted with a presumptive recurrence of a nonsecreting pituitary macroadenoma (the first diagnosis, in another service). Magnetic Resonance Imaging (MRI) confirmed an expansive solid isointense lesion in the posterior region of the sella with suprasellar component (Figure 1)...

The extrapontine myelinolysis of osmotic demyelination syndrome (ODS) is a well-known but uncommon disorder of the central nervous system. Although the mechanism is not fully understood and the treatment is controversial, hyponatremia is probably considered to be the main pathophysiological basis. There are few reports of ODS caused by a sellar lesion. Here we present a case of suprasellar arac...

• Intracranial germinoma is the most common malignant intracranial germ cell tumor. It usually occurs in children and young adults and with the current therapies, many patients experience long-term survival. • Suprasellar region germinoma can present with isolated hypothalamic–pituitary axis dysfunction such as diabetes insipidus, delayed growth, menstrual irregularities, or precocious puberty,...
