title: Rathke's cleft cyst: a clinical and radiographic review.
abstract: We report the case of a 62-year-old woman, who had a 4-year history of progressive visual acuity deficit. On neurological examination, visual acuity was 5/20 in the right and 4/20 in the left eye. A hormonal study revealed hypophyseal hypofunction. CT and MRI scans showed an intra-suprasellar cystic lesion, hyperintense in T1 and hyperintense in T2-weighted sequences. At surgery, the cyst wall was opened and the cavity placed in communication with the subarachnoid space. Histological examination showed a Rathke's cleft cyst. After four years of follow-up the patient's visual deficit remained unchanged, whereas the results of the hormonal assays were normal. An MRI scan confirmed the absence of the cyst. We review 216 reported cases of Rathke's cyst and discuss its pathogenesis, clinical features and treatment.
