ABSTRACT

Diagnosis: Colloid cyst.

History: 29 year old female with worsening headaches.

Findings: 11 x 11 x 13 mm nonenhancing well-circumscribed mildly T1 hyperintense and markedly T2 hypointense round mass in the anterior-superior third ventricle without ventricular enlargement.

Ddx: Colloid cyst. Although other lesions can occur in this region such as ependymoma, subependymoma, giant cell astrocytoma and central neurocytoma,the imaging findings are characteristic for a colloid cyst.

Dxhow: Imaging characteristics.

Exam: non-focal neurologic examination.

No MeSH data available.


There is a well-circumscribed mildly T1 hyperintense and markedly T2 hypointense, nonenhancing mass, in the anterior-superior third ventricle.  The hypointensity has been called the "black hole" effect of Colloid Cyst.
