Craniopharyngiomas are benign slow growing tumours that are located within the sellar and para sellar region of the central nervous system. The point prevalence of this tumour is approximately 2/100,000. The onset of symptoms is normally insidious with most patients at diagnosis having neurological (headaches, visual disturbances) and endocrine (growth retardation, delayed puberty) dysfunctions...
In central nervous system, schwannomas, as ubiquitous tumors, mostly originate from sensory nerves like auditory and trigeminal nerves. However, intrasellar schwannomas are extremely rare. They are often misdiagnosed as pituitary adenomas. We report a rare case of schwannoma in the sellar region--a challenging diagnosis guided by clinical presentations, radiological signs, and postoperative pat...
Chondromas originating from the sella turcica are rare, and the most common initial symptoms are headache and visual disturbance. We describe a case of sellar chondroma with endocrine impairment as an initial manifestation that completely resolved after surgery. A 40-year-old Japanese woman with amenorrhea and galactorrhea for the last 2 years was referred to our department of neurosurgery for ...
Xanthogranuloma of the sellar region is a very rare brain tumor with favorable prognosis and without reported relapses of purely xanthogranulomatous lesion after complete resection. A case is presented of a 40-year-old male diagnosed with and treated for sarcoidosis, complaining of headache, photophobia and loss of libido. Physical examination revealed generally scarce hairiness, while laborato...
Five Japanese children presented with rare xanthogranuloma located in the sellar region between 2000 and 2010 at the Department of Neurosurgery, Hokkaido University Hospital. Endocrinological examination disclosed central diabetes in four patients. Preoperative magnetic resonance (MR) imaging and computed tomography (CT) demonstrated clearly defined intra- or suprasellar masses appearing as iso...
PURPOSE To investigate the prevalence and physical basis of a specific form of MR susceptibility artifact that may be seen in the pituitary gland near the junction of sellar floor and sphenoidal septum. MATERIALS AND METHODS Coronal, T1-weighted MR images of the pituitary glands in 50 subjects without clinical evidence of pituitary or sphenoidal sinus disease were reviewed to determine the pr...
