To the Editor: A 36‐year‐old female patient was admitted to Peking Union Medical College Hospital complaining of 6 years of headache. Magnetic resonance imaging (MRI) showed an intrasellar lesion with homogeneous hyperintense on T1‐weighted images and T2‐weighted images and inhomogeneous contrast enhancement by the gadolinium administration [Figure 1a and 1b]. Rathke’s cleft cyst was initially ...

Colloid cysts appear most commonly in the third ventricle, their occurrence in the sellar region is uncommon. The authors report a female patient with a pituitary colloid cyst. She was diagnosed incidentally with a sellar lesion by a routine paranasal computed tomography examination performed for planning of a dental implant surgery. Radiologic examinations revealed a pituitary lesion that was ...

Giant intra and parasellar aneurysm with a spontaneous thrombosis of internal carotid artery is rare. We report the case of a 34 years old woman presenting a unique giant sellar and parasellar aneurysm associated with hypopituitarism and amenorrhea-galactorrhea syndrome. Computed tomographic scans and magnetic resonance images were suggestive of a sellar tumor with a cystic component. Digital c...

Craniopharyngiomas (CPs) are clinically relevant tumors of the sellar region and are associated with high morbidity and occasional mortality. There are two different subtypes of CPs that differ clinically and pathologically: adamantinomatous CP and papillary CP. The differential diagnosis is still challenging even with developments in preoperative imaging as several tumors of the sellar/parasel...

A 54-year-old woman presented with a 3-month-history of blurred vision and refractory headache. Examination revealed severe bilateral visual acuity compromise, normal campimetry and bilateral papilledema. As a mean to investigate raised intracranial pressure, neuroimaging studies were performed and showed extensive sellar mass (Figure). Patient underwent transsphenoidal approach for resection o...
