An 11-year-old castrated Schnauzer presented with paraplegia for the last two weeks, initially developedpelvic limb ataxia 6 months ago and left pelvic limb paresis 3 months ago. On neurological examination, paraplegiaand postural reaction deficits were noted in the pelvic limbs with no deep pain sensation, and the dog showedexaggerated spinal reflexes and involuntary urination. Magnetic resonance (MR) images of thoracolumbar spinal cordwere obtained with a 0.3 Tesla magnet. A mass with a broad base to the dorsal and left dural margins was identifiedat the level of L2, causing marked spinal cord compression. The mass showed isointensity to the spinal cord on T1-weighted (T1W) precontrast images, hyperintensity on T2-weighted images, marked homogeneous contrast enhancementwith well-defined margins and the “dural tail” sign on T1W postcontrast images. An intradural-extramedullay tumorwas considered, most likely, meningioma was highly suggestive. Left-sided hemilaminectomy and dorsal laminectomywere performed. An intradural mass partially adherent to dura mater was compressing the spinal cord, and the masswas completely removed with the attached dura mater. A histopathologic diagnosis of angiomatous subtype meningiomawas made.
