Granulomas can “mimic” gliomas on magnetic resonance imaging (MRI) in human patients. The goal of this retrospective study was to report canine brain granulomas that were consistent with glioma based upon MRI, report their histologic diagnosis, and identify MRI criteria that might be useful to distinguish granuloma from glioma. Ten granulomas, initially suspected to be glioma based on MRI, were ultimately diagnosed as granulomatous meningoencephalomyelitis (n = 5), infectious granulomas (n = 3) or other meningoencephalitis (n = 2). Age was 1.6–15.0 years and two dogs were brachycephalic breeds. MRI characteristics overlapping with glioma included intra-axial, heterogeneous, …

Endoscopic Laser-Ablation For The Treatment Of Orthotopic And Ectopic Ureteroceles In Dogs: 13 Cases (2008-2017)., Cleo P. Rogatko, Allyson C. Berent, Larry G. Adams, Chick W. Weisse, Demetrius H. Bagley

Department of Urology Faculty Papers

BACKGROUND: Ureteroceles are a rare condition in dogs in which conventional treatments can result in substantial morbidity. Cystoscopic and fluoroscopic-guided laser ablation (CLA) of ureteroceles can successfully relieve obstruction.

OBJECTIVES: To describe the technique and outcomes of attempting CLA for treatment of ureteroceles in dogs.

ANIMALS: Thirteen client-owned dogs that underwent CLA for treatment of ureteroceles.

METHODS: Retrospective multicentered study. Medical records were reviewed in all dogs that underwent CLA for ureterocele(s). A laser was used to extend the opening of the ureteral orifice (UO) unless surgical conversion was necessary. Data collected included signalment, clinicopathologic data, imaging, procedural findings, complications, …
