Canine Choroid Plexus Tumor with Intracranial Dissemination Presenting as Multiple Cystic Lesions
Figure 1
Transverse magnetic resonance images (MRIs) at the level of the mesencephalic aqueduct. (a) T2W image (TE/TR, 104/4440 ms) with several round lesions within the caudal thalamus that are isoattenuating to cerebrospinal fluid within the lateral ventricles. (b) These lesions null on FLAIR sequences (TR/TE, 78/9000 ms) with mild perilesional hyperintensities representing edema. (c) The lesions are isoattenuating to CSF on T1W images (TE/TR, 12/53 ms) and have mild contrast enhancement of the lesion wall (d).
