Abstract :The aim of this study was to report the magnetic resonance imaging insert ignore into journalissuearticles values(MRI); findings of intracranial tumors in 26 dogs. The medical records of dogs admitted to the Department of Surgery, Faculty of Veterinary Medicine, Ankara University for central nervous system disorders were reviewed, and dogs with intracranial tumors that were diagnosed with MRI between November 1997 and June 2006 were included in the study. MR images were obtained as T1 weighted insert ignore into journalissuearticles values(T1W);, T2 weighted insert ignore into journalissuearticles values(T2W);, and contrast enhanced T1 weighted insert ignore into journalissuearticles values(following Gd-DTPA administration); in the transverse, coronal insert ignore into journalissuearticles values(dorsal);, and sagittal planes. The following features were evaluated in order to characterize the lesions and to establish diagnoses based on radiological findings: site of origin, anatomic location, signal characteristics on T1W and T2W images, contrast enhancement, shape and size, number insert ignore into journalissuearticles values(multiple or single);, and presence of edema and midline shift. The radiological diagnoses were as follows: intracranially invading sinus tumor insert ignore into journalissuearticles values(n = 3);, meningioma insert ignore into journalissuearticles values(n = 7);, choroid plexus tumor or ependymoma insert ignore into journalissuearticles values(n = 3);, ependymoma insert ignore into journalissuearticles values(n = 1);, glioma insert ignore into journalissuearticles values(n = 5);, metastatic tumor insert ignore into journalissuearticles values(n = 3);, astrocytoma insert ignore into journalissuearticles values(n = 1);, astrocytoma or metastasis insert ignore into journalissuearticles values(n = 1);, cavernoma insert ignore into journalissuearticles values(n = 1);, and hypophyseal adenoma insert ignore into journalissuearticles values(n = 1);. In conclusion, lesions occupying the intracranial space can be accurately diagnosed and tumor type can be predicted with MRI.
