Abscess and perirectal fistulas are common in humans but not so in animals. Fistulas located in tissues surrounding the anus are usually described in the course of furunculosis in dogs. This study presents the case of a one-year-old cat in which two rectocutaneous fistulas had formed. This process was a result of the chronic inflammation of tissues around the base of the tail due to the drainage of an abscess. The animal was referred for radiological examination with clinical signs of dyschezia. Faecal material was discharged only through the fistulas situated on both sides of the tail. The aim of the radiological examination was to preoperatively determine the course of the fistula tract and to identify their internal openings. Fistulography revealed that both fistulas were connected with each other and with the rectal lumen. Their external opening was located at the height of the 4th caudal vertebra, 1.5 cm (fistula on the right) and 2 cm (fistula on the left) from the wall of the rectum. The fistula located on the right side branched cranially. The rectal lumen in this area was significantly narrowed. Abscess formation resulting in the development of rectocutaneous fistulas has not yet been described in dogs or cats. In the present case, fistulography made it possible to identify directly the source and course of the fistula canal. This examination should be complemented by other diagnostic modalities, such as a contrast examination of the gastrointerstinal tract, ultrasound evaluation, and magnetic resonance imaging.

This study was performed to make a surgical model of osteoarthritis (OA) in the dog. Experimental medial patellar luxation (MPL) was surgically produced in the left stifle (index) of 24 skeletally mature mixed small breed dogs (age two to six years and weight 2.8 to 9 kg). The animals were randomly allocated in 2 groups; sham group (n = 12), where the right stifle was sham operated and control group (n = 12) with intact right stifle. Physical and radiographic examinations of both stifles were performed at 1.5 months intervals over a one-year experimental period. One dog was euthanatized every three months, and both stifles were explored, gross examination was performed and tissue samples from the articular cartilage, cranial cruciate ligament (CCL) and synovium were collected for histomorphology. The clinical signs of OA were obvious in the experimental dogs by 12 weeks of surgical induction of MPL, which was also evidenced in the histopathology of the joint tissues and electron microscopy of the articular cartilage. The radiographic changes of OA were not obvious until remarkable degenerative changes became abvious six months postoperatively. Surgically induced MPL can be a successful tool for experimental induction of OA in dogs.

A Furioso-North Star mare, aged 8 years, was examined for colic signs. The mare had a history of dystocia and post partum vaginal lacerations, acute endometritis and laminitis approximately one year before the admission for colic. Signs of persistent abdominal pain, moderate distended abdomen, non-passage of manure, fever, tachycardia, tachypnoea, congested mucus membranes, and “toxic line” were recorded. No intestinal borborygmi were present in the four quarters of the abdomen. On rectal examination, the colon, the ventral band of the caecum, the right ovary and the uterine horn were palpated on the right side of the abdomen. The spleen, the nephrosplenic ligament, the left ovary and a firm, distended and painful small intestine (SI) loop were palpated on the left side. The left uterine horn and the adjacent broad ligament were not detectable. Percutaneous abdominal ultrasound evaluation revealed a large amount of fluid in the abdominal cavity, SI distention and absence of peristalsis. Abdominocentesis yielded approximately 20 ml of red-tinged peritoneal fluid with increased mean protein concentration (5.2 mg/dl), white blood cell count (12,550 cells/μl), and lactate (14 mmol/dl). A presumptive diagnosis of SI strangulation was made. Surgical resection of the affected intestinal loops was recommended. Due to poor prognosis and financial limitations, the mare was euthanized. Post mortem macroscopic diagnosis was a herniation of 3 metres of the mid-jejunum through the left mesometrium, resulting in a complete and complicated strangulation. To prevent this type of SI strangulation, we recommend transrectal palpation of the urogenital tract (including the broad ligament) after foaling. If a defect is identified, we recommend flank laparoscopy for correction.

Internal carotid artery (ICA) dissection is a cause of stroke, but it is often underdiagnosed in children. ICAs’ risk factors and pathogenic mechanisms are poorly understood, and the treatment is still empirical. We report the case of a previously healthy 9-year-old girl who presented with involuntary hypertonic closure of the right hand associated with transient difficulty for both fine movements of the right arm and speech. She had a history of minor cervical trauma occurring 20 days prior to our observation without other associated risk factors. Magnetic resonance imaging and magnetic resonance angiography showed ischemic lesions due to the left ICA dissection. Treatment with both acetylsalicylic acid and levetiracetam allowed recanalization of the ICA associated with the resolution of clinical signs. Our clinical case suggests that the ICA dissection must be suspected early whenever a child manifests mild neurologic deficits after a cervical trauma, especially if they are associated with headache and/or cervical pain. Moreover, the management of ICA dissection must be improved.

This case report is about a seven-year-old male neutered European Shorthair cat infected by Dirofilaria immitis as the first reported autochthonous Dirofilaria immitis infection in Austria. There was no history of periods abroad. Echocardiography showed suspected D. immitis in the right cardiac chamber with increased pulmonary pressure and ascites. Surgical removal of the heartworms was performed. Twenty adult heartworms were removed by transvenous jugular approach under general anesthesia and stored in 4% formalin. Five out of 20 specimens were examined via light and stereomicroscopy and feline heartworm infection was confirmed. Amplification of a 203 bp or 724 bp fragment of the cytochrome c oxidase subunit I gene was unsuccessful. After surgery the cat developed acute renal failure but recovered quickly. One year later, the cat underwent a control examination including echocardiography and blood work. There were no more D. immitis detectable at echocardiography. Lung pressure was mildly increased. Complete blood count and creatinine were unremarkable. The Knott’s test and Dirofilaria-Antigen-test produced negative results. The cat did not show any clinical signs during the follow-up period. The aim of this case report is to highlight the growing risk of acquiring infection with D. immitis not only for Austrian dogs, but also for cats. This case report represents the first report of autochthonous D. immitis infection in Austria. Moreover, even if the prognosis in cats with caval syndrome due to feline heartworm disease is guarded to poor, surgical removal of the filariae can be a successful treatment option.

A nine-year-old, male, neutered domestic shorthair cat was referred with a three-month history of abnormal behavior. On neurological examination, the cat showed circling towards the left. Magnetic resonance imaging of the brain revealed an extra-axial mass at the level of the left forebrain surrounded by a large peritumoral (pseudo)cyst. A left-sided rostrotentorial craniectomy to drain the fluid and to remove the tumor was performed. On histopathologic examination, the presence of a meningioma was confirmed. The owners did not report any clinical signs one year postoperatively.

In this case report, an eight-year-old Warmblood gelding is described with a presumptive vascular event resulting in severe head turn and circling to the right. The horse recovered completely from the clinical signs. Pathologies that cause asymmetrical forebrain signs in horses could be excluded. Magnetic resonance imaging revealed a flow difference in the venous sinuses that was presumably caused by cerebral venous sinus thrombosis. The horse was treated with prednisolone, antibiotics, vitamin E and B1 and acetylsalicylic acid. He was represented one month after the initial clinical signs and was clinically and neurologically normal. The horse subsequently returned to his previous level of jumping.

The aim of the study was to determine the diagnostic usefulness of magnetic resonance imaging (MRI) and brainstem auditory evoked responses (BAER) in dogs suspected of having cerebellar cortical degeneration (CCD). In the years 2009–2011, six dogs with suspected CCD were examined. Both MRI and BAER examinations revealed abnormalities in all dogs (100%). By MRI, T2-weighted midsagittal images revealed an increased amount of cerebrospinal fluid (CSF) surrounding the cerebellum within the sulci of the folia in all dogs (100%). In 4 out of the 6 dogs (66.66%), cerebellar hypoplasia was more visible in the region of the dorsal cerebellar lobules. In 5 out of the 6 dogs (83.33%), the fourth ventricle was enlarged. In our studies, the brain to cerebellum ratio evaluated on the midsagittal image was 11.93%, in comparison to 14.9% in normal dogs. By BAER examination, the amplitude of the first and second waves was diminished and III–V interlatency was prolonged in 5 out of the 6 dogs (83.33%). In one out of the 6 dogs (16.67%), only the III–V interlatency was prolonged. In one dog (16.67%), somato-nervous deafness in the left ear was detected, whereas in the right ear the III–V interlatency was prolonged. MRI of the cerebellum is a reliable method for the antemortem diagnosis of CCD in American Staffordshire terriers, as is BAER examination. BAER is an objective diagnostic tool, which — along with other diagnostic modalities — can be helpful in the assessment, management and follow-up of dogs with cerebellar abiotrophy. It proved to be useful in determining the severity of neurological lesions in comparison to MRI findings, as well as in assessing the prognosis.

A 30-year-old woman presented to our outpatient department with complaints of pain and swelling in bilateral infrapatellar regions and a discharging sinus in the right knee over the duration of one year. Radiographs showed lytic regions in bilateral patellae. Samples sent from material curetted from sinus yielded no organism but histopathology reported granulomatous inflammation. Following a fresh magnetic resonance imaging (MRI) scan that revealed the infrapatellar pad of fat communicating with the patellar lesions, an exploration and evacuation was done. Material sent revealed epithelioid cell granulomas with caseous necrosis consistent with tuberculosis (TB). The patient was put on first line anti-tubercular treatment (ATT) and has responded favourably with healing of sinus and patellar lesions. Bilateral infrapatellar bursitis is not rare. However patellar TB as a cause for OMIT is not a common diagnosis. A bilateral patellar involvement has not been reported in literature to the best of our knowledge.

AbstractWe report a case of a 40-year-old man presenting with acute vertigo and deafness. Computed tomography (CT) scanning at initial presentation was normal. However, one year later he developed numbness on the right side of his face and examination revealed fifth, seventh and eighth cranial nerve palsies as well as cerebellar dysfunction. Magnetic resonance imaging (MRI) demonstrated a cerebellopontine angle lesion. He underwent near total excision followed by neuro-axis irradiation. The main mass of the tumour projected into the cerebellopontine angle. Histology showed this to be a medulloblastoma. All features of this case are unusual; hence we discuss the pathogenesis and management of this very rare tumour.

We report a case of intravenous lobular capillary hemangioma in the subclavian vein, causing venous thoracic outlet syndrome. A 32-year-old woman was referred to our unit with facial and left arm oedema. Ultrasound evaluation, computed tomography and magnetic resonance imaging showed a hypervascular mass in the middle portion of the subclavian vein, with arrest of venous flow. Through an infraclavicular approach, we excised the venous axis with the endovascular palpable tumour that extended from the axillary-subclavian junction to the jugular-subclavian junction, without reconstruction. The postoperative period was uneventful. The patient recovered well without recurrence at one year from surgery.
