For each lesion, 2 readers, blinded of medical history, have evaluated 6 sets of images: set A (T1/T2-weighted images), set B (set A + DWI), set C (set B + apparent diffusion coefficient [ADC] map), set D (set A + dynamic and hepatobiliary phases), set E (set D + DWI), set F (set E + ADC map). In rare cases, if the cyst is large, it may cause abdominal pain or nausea, vomiting, and early satiety. Their marked hyperintensity on T2-weighted imaging provides greater confidence toward the diagnosis of small cysts on MRI. When they say did not completely fill with contrast, that hints to me that they are thinking hemangiomas. Normal vascular flow voids identified at the skull base.

Generally, cysts and hemangiomas have a higher and homogeneous intensity in T2 compared with malignant lesions (2). For potential or actual medical emergencies, immediately call 911 or your local emergency service. Septa and solid nodules can be readily seen within cysts on T2-weighted images due to their relatively low signal intensity compared with the fluid contents within the cyst. Patients with extensive white matter hyperintensities are likely to have tension-type headaches or to have headaches develop during middle age, according to results published in Cephalagia.
