A pulmonary infiltration with eosinophils in a male Husky is described in this paper. The clinical signs, such as dyspnoea and coughing, were present for four days. A diagnosis was obtained by radiography of the thorax and a bronchoalveolar lavage. A treatment of prednisolone was given and resulted in a complete recovery of the patient. The literature on the different techniques to take a sample (the translaryngeal, the transtracheal and the bronchoalveolar lavage), the differential diagnosis, the diagnosis and the treatment are furthermore discussed. A good differential diagnosis is important for a correct prognosis and treatment.

Cryptococcosis is a subacute to chronic fungal disease that can occur in several species. This disease is usually seen in warm climates, and only a few cases have been described in moderate climate regions. The disease can remain localized in the nose and sinuses, but often extends to lungs, brain, and skin. In this report, the first case of disseminated cryptococcosis in a cat in Belgium is described.

A 7-year-old Jack Russell Terrier was presented with a history of inability to jump, inability to wag its tail and pain in the back for the past 8 months. Myelography revealed an intradural lumbar mass, which was histologically determined to be an atypical meningioma. The most frequent topography of this neoplasm is intracranial.

This case report describes a severe outbreak of equine herpesvirus 1 (EHV-1)-induced neurological disorders in horses on a riding school in Belgium. On at least 10 premises that had been in direct or indirect contact with the riding school during the onset of the outbreak, fever was reported. On 7 of these in-contact premises, horses also suffered from neurological disease. Of all the horses, 42 % showed fever and anorexy. Neurological disorders were observed in 15 % of all the horses. The disorders consisted mainly of ataxia and paralysis of hind limb and tail (76 % of the neurologically affected horses). Cerebral disorders such as blindness, torticollis and severe apathy were observed in 24 % of the neurologically affected horses. The mortality during the epidemic was 10 %. EHV-1 was isolated from blood mononuclear cells of two horses and identified using EHV-1-specific monoclonal antibodies.

This paper is the first description of an ependymoma in a sheep, diagnosed by chance from a fallen stock sheep included in the TSE epidemiosurveillance. Macroscopically only a very small grayish fluffy mass was present in the third ventricle of the mid-brain. Microscopically, the fluffy mass was diagnosed as an ependymoma.

In this case report, a severe infection with Sarcoptes scabiei in llamas is described. Sarcoptic mange is common in small camelids, but is often detected too late. In this case, the llamas showed severe signs of pruritus, hyperkeratinization, alopecia and pyodermy. Psoroptes mites were found in the ear and an otitis was present. One llama died and showed an abcedation of the ear base. A treatment with doramectine S.C. in combination with a topical applied acaricid had to be repeated seven times before it was successful. Llamas, which are newly introduced in a herd, have to be inspected and treated thoroughly in order to prevent transmission of the infection to other animals.

An aneurysmal bone cyst was diagnosed in the pelvis of a 3 1/2-year-old domestic short-hair cat. Clinically, the cat was suffering from tenesmus and dysuria. Radiographs showed an expansive lytic lesion appearing as a subperiosteal ‘blow-out’ of the ventral aspects of the pubic and ischial bones. Definitive diagnosis was provided by histopathology. The veterinary literature on aneurysmal bone cysts is reviewed.

In this report a case of prosencephalic hypoplasia in a stillborn calf is described. It is characterized by the absence of the cerebral hemispheres, malformation of the diencephalon and cerebellum, and an abnormally flattened calvaria with cranioschisis and encephalocele. The absence of the telencephalon is also typical of anencephaly and hydranencephaly, from which prosencephalic hypoplasia has to be differentiated. These three types of congenital malformations of the bovine brain are briefly discussed with special focus on their morphologic characteristics in order to allow a specific diagnosis.

This report describes a case of a severely lame horse referred for an obvious muscular swelling at the level of the right crus. The horse was in poor condition. An initial diagnosis of trauma with intramuscular hemorrhage was made. Nineteen days following the first examination, the horse was euthanized because of disseminated hemangiosarcoma. The clinical findings, the therapeutic possibilities and the observations at necropsy are discussed.

A 19-month-old, male Shih Tzu dog was examined for psoriasiform lesions on the concave aspect of both ear pinnae. On histopathology a band-like superficial dermatitis with lympho-plasmacytic infiltrate was observed. A coagulase-positive hemolytic Staphyloccoccus (S. intermedius) was isolated from the skin lesions. Treatment with cephalexin resulted in complete resolution of the lesions. This case showed similarities with the psoriasiform lichenoid dermatitis in English Springer Spaniels.
