RESUMO
Background: Intravascular lymphoma (IL) is a rare disease characterized by presence of neoplastic lymphocytes in thelumen of blood vessels. Any tissue can be affected; however, the most frequently compromised areas of the body are theskin and the central nervous system (CNS). The clinical signs and macroscopic alterations caused by IL are nonspecific andare usually secondary to a continuous proliferative disorder, which leads to occlusion of the blood vessels with consequentthrombosis, hemorrhage and infarction. The objective of this work is to report a case of IL in a dog.Case: An 8-year-old male Rottweiler dog was referred to the Veterinary Hospital of the Federal University of Paraná witha history of cerebellar ataxia that had not improved after treatment. At the neurological examination, cerebellar ataxia anddeficit of nasal reflex were detected. A complete blood count showed presence of slight anemia (4.8 million red bloodcells/mm3; normal ranges= 5.5-8.5 million/mm3) and thrombocytopenia (176.000/mm3; normal ranges= 250.000-500.000/mm3). Biochemical tests revealed a small increase in alanine aminotransferase (42 IU/L; normal ranges= 14-38 IU/L) and aslight decrease in alkaline phosphatase (49 IU/L; normal ranges= 90-170 IU/L). The cerebrospinal fluid (CSF) exhibited anincreased protein concentration (147.3 mg/dL; normal ranges= 18-44 mg/dL) and pleocytosis (8 cells/µL; normal ranges=up to 5 cells/µL). No alterations were observed at radiographic and ultrasonographic exams. A clinical treatment was prescribed; however, in view of the worsening of the clinical signs, euthanasia was performed, and the body was submittedto a Laboratory of Pathology. At necropsy, moderate multifocal ulcers were observed in the oral cavity and ventral side ofthe tongue; moderately infarcted areas were detected in the spleen. Additional alterations such as fatty liver degeneration...(AU)

Background: The loss of natural habitats associated with the development of humanity resulted in the need for longer trips and greater interaction with highways by some animal species. Vehicle collision with animals is one of the main factors of pressure over wild animal populations in Brazil; veterinary surgery can play an important role for the recovery of these patients. The lesions commonly seen in animals hit by vehicles may comprise skin lesions, central nervous system injuries, intrathoracic and intra-abdominal complications, among which renal lesions are included. The aim of this work is to report the use of a total nephrectomy technique in a crab-eating fox. Case: A female, adult, 5-kg crab-eating fox (Cerdocyon thous Linnaeus, 1766) was received for emergency care at the Veterinary Hospital of Universidade Federal do Paraná at Palotina. The patient had been struck by a vehicle at a local highway, was unconscious, and exhibited signs of blood loss such as hypothermia, hypotension, and pale mucous membranes. As the clinical evaluation was performed, the patient was stabilized with pain management, correction of hypovolemia and hypothermia, and oxygen therapy. Blood samples were taken in case of the need for preoperative tests. Subsequently, the animal was submitted to the diagnostic imaging section to investigate possible injuries. No chemical restraint was necessary for the procedures. Radiography examination revealed loss of intra-abdominal contrast, which was confirmed to be free fluid on ultrasound examination. Immediately after imaging examination, the animal was taken to the surgical room for exploratory laparotomy. The surgical incision, which was performed over the linea alba, extended from the xiphoid process to the pubis...(AU)
