  • Title: [A case of spontaneous rupture of a suprasellar cystic mass].
    Author: Terao T, Sawauchi S, Hashimoto T, Miyazaki Y, Akiba Y, Abe T.
    Journal: No Shinkei Geka; 2001 Aug; 29(8):755-8. PubMed ID: 11554094.
    Abstract:
    The author reported a case of a spontaneous rupture of a suprasellar cystic tumor. A 67-year-old man complained of bitemporal homonymous hemianopsia. His visual acuity was 0.02 on the right side and 0.04 on the left side. Skull XP revealed no abnormal findings, but brain CT scan showed a cystic mass without calcification in the suprasellar region. Brain MRI at the same lesion site depicted a low-intensity mass on T1-weighted image without gadolinium enhancement, and a high-intensity mass on T2-weighted image. The patient was treated conservatively because of complications such as diabetes mellitus, cerebral infarction and old myocardiac infarction. MRI taken 5 years after the initial MRI revealed disappearance of the suprasellar cystic mass. However, the patient's neurological findings, including visual signs, revealed no deterioration. His physical and radiological findings had remained uneventful. In this report, we reviewed the literatures about spontaneous rupture of suprasellar cystic tumors. It was considered that in this case, according to the neurological, radiological and CSF findings, the suprasellar cystic mass might be a Rathke's cleft cyst or arachnoid cyst.
