Nonneoplastic disorders of the brain	2005-07-06		.txt	text/plain	11283	790	44	Computed tomography (CT) and magnetic resonance imaging (MRI) are helpful in the diagnosis of many nonneoplastic brain disorders in the dog and cat. Experimentally, acute obstructive hydrocephalus in dogs causes edema starting at the dorsolateral angles of the lateral ventricles and spreading into the adjacent white matter, n On CT, this is evident as blurring or loss of the normally sharp ventricular margins. ~<18-21 In contrast to human patients, most dogs and cats with this syndrome do not have obvious enlargement of the caudal fossa, ls-21 Neurological deficits typically occur at a young age and primarily reflect cerebellar dysfunction, including ataxia, hypermetria, intention tremor, and vestibular dysfunction, ls-21 On CT and MRI, Dandy-Walker malformation is characterized by an enlarged caudal fossa filled by an enormous fourth ventricle and a small cerebellum. 43,45 At this stage the hematoma is still hypointense on T2-welghted images23 Other causes of T1 hyperintensity or T2 hypointenslty include fat, calcification, mucinous material, intratumoral melanin, flow effects, and enhancement with paramagnetic contrast agents23 Extracellular methemoglobin.	./cache/cord-008085-3ihuqvei.txt	./txt/cord-008085-3ihuqvei.txt
