Since computed tomography (CT) was introduced to veterinary medicine in the beginnings of the 80s, the CT of the skull has mainly been used for the diagnosis of brain tumors. The present study includes 18 dogs and five cats, all patients of the Clinic of Small Animals of the School of Veterinary Medicine Hannover. After a CT of their skull was made, a primary intracranial neoplasm was confirmed by a pathomorphological and -histogical examination post mortem. Four of the five cats had a meningioma, one cat an astrocytoma. With five cases the meningioma also predominated in the dogs, followed by primary lymphoma with four cases. An astrocytoma, an oligodendroglioma and a choroid plexus papilloma were diagnosed respectively in two dogs. A pituitary gland tumor, a germ cell tumor and a medulloblastoma represented individual cases. Based on the pathomorphologically and -histologically confirmed diagnosis, characteristics of these primary brain neoplasms can be found in their CT image. However, changes are not pathognomonic for a certain type of tumor; a definitive diagnosis cannot be made from the CT image.
自20世纪80年代初计算机断层扫描（CT）被引入兽医学以来，颅骨CT主要用于脑肿瘤的诊断。本研究包括18只犬和5只猫，均为汉诺威兽医学院小动物诊所的患者。在对它们进行颅骨CT检查后，通过死后病理形态学和组织学检查确诊为原发性颅内肿瘤。5只猫中有4只患有脑膜瘤，1只猫患有星形细胞瘤。犬中也是脑膜瘤占主导，有5例，其次是原发性淋巴瘤，有4例。分别在2只犬中诊断出星形细胞瘤、少突胶质细胞瘤和脉络丛乳头状瘤。垂体瘤、生殖细胞瘤和髓母细胞瘤各为个别病例。基于病理形态学和组织学确诊的诊断，可以在这些原发性脑肿瘤的CT图像中发现其特征。然而，这些变化并非某一特定类型肿瘤所特有；无法从CT图像做出明确诊断。
