Kidney cysts are round pouches of fluid that form on or in the kidneys. 003) and T2 ( p = 0. Bleeding near the mass. T2 signal intensity between fat and water can be optimized by selecting for a longer TE [4]. Smaller masses are more likely to be benign. a Axial T2-weighted MR image shows a lesion (arrow) with strong hyperintensity and a thin wall. The major lesions that contain a myxoid matrix are neurogenic tumors, myxoid liposarcoma, and myxofibrosarcoma (2, 31). These are the most common symptoms of the cortical cyst: If the cortical cyst becomes large enough, a palpable mass can be felt in the kidney area. Hello and hope you are doing well. Most MRI reports are black and white with shades of gray. Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific.

It will also allow a look at the lesion before giving dye through the vein and after. Follow-up ultrasound showed the lesion in the superficial lobe of the left parotid gland, adjacent to the retromandibular vein, with slow flow around the lesion in colour Doppler examination. The hyperintense lesion could be due to a cyst or tumor. White matter hyperintensities (WMHs) are lesions in the brain that show up as areas of increased brightness when visualised by T2-weighted magnetic resonance imaging (MRI). Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics. Ball-type lesions are the most common and present as expansile masses, deforming the renal contour.
