    Abstract:
    PURPOSE: We describe a surgical case of aseptic meningitis and secondary hypophysitis due to rupture of a Rathke's cleft cyst(RCC)and report on literature considerations. CASE: A 36-year-old woman with a past history of menstrual irregularity who had been taking a low-dose contraceptive for five years visited our hospital. She had discomfort in her right eye four years earlier. A waxy nodule observed on MRI was diagnosed to be an asymptomatic RCC. She experienced periodic headaches and retrobulbar pain without any prior history. MRI showed dural thickening on gadolinium-T1-weighted(GdT1)imaging, disappearance of the waxy nodule on T1/T2-weighted imaging, signal change of the cyst contents, and suspected cerebrospinal fluid in the pre-pontine cistern. Aseptic meningitis or hemorrhagic adenoma due to RCC rupture was suspected, and endoscopic transsphenoidal surgery was performed on day 26. The pathological results indicated that the ruptured RCC had resulted in aseptic meningitis and secondary hypophysitis. CONCLUSION: If the rupture of an RCC is suspected and subsequent secondary hypophysitis and optic neuritis are observed, early diagnosis and surgery with informed consent are essential. This is because of the high risk for panhypopituitarism with vision loss and visual field disturbance.
