Magnetic Resonance Imaging Features of Multilobular Osteochondrosarcoma in 3 Dogs

Lipsitz D., Levitski R.E. and Berry W.L.

Vet Radiol Ultrasound, 2001. 42(1): p.14-9.

Three dogs with multilobular osteochondrosarcoma of the skull were evaluated using magnetic resonance (MR) imaging. Spin echo T1, T2, proton weighted and post contrast T1W images were obtained with a 1.5 Tesla magnet. The MR imaging findings were similar in all three dogs with mixed signal intensities in the T1W, T2W and proton weighted images and fairly large areas of contrast enhancement in the post contrast T1W images. The extent of brain and soft tissue involvement were well delineated and provided useful information concerning surgical planning. MR imaging provided a useful method of evaluating dogs with skull tumors.
