Abstract: 
A five-year-old, female scaly-sided merganser was presented with a chronic recurrent conjunctivitisof the left eye. Physical examination showed a caseous nodular lesion at the palpebral conjunctiva associatedwith excessive tearing. Necropsy revealed caseous necrotic debris at the left conjunctiva andinfra-orbital sinus, but also multiple granuloma in several internal organs. Histological examinationshowed granulomatous splenitis, hepatitis, arteritis, fibrinonecrotic enteritis and conjunctivitis, andalso amyloidosis of liver and spleen. Bacterial and molecular tests of a conjunctival swab in the liveanimal showed the presence of a multiresistant Escherichia coli strain and Chlamydia psittaci, respectively.These bacteria had only a secondary pathogenic role. No premortem cytological examinationor Ziehl-Neelsen (ZN) staining of the histological section of the conjunctiva biopt or additional tests,such as blood test and radiographs, were performed. Finally, a Mycobacterium avium infection of theconjunctiva and internal organs was confirmed following necropsy by ZN staining and PCR analysis.Local and systemic antimicrobial treatments with fluoroquinolones, tetracyclines and aminoglycosideswere unsuccessful.

Title: 
Microsporum gypseum infection in a horse with severe sweet itch
Author(s): 
F. BOYEN, P. VAN ROOIJ, L. VANSTALLEN, B. FLAHOU, F. HAESEBROUCK
Abstract: 
In a horse with severe sweet itch and a history of corticosteroid treatment for this disorder,a single, well-circumscribed and crusty white lesion was present on the thigh. The geophilicdermatophyte species M. gypseum was cultured from the lesion. The lesion was treated topicallyonce a week with an enilconazole emulsion for four weeks. Full recovery was noted after twomonths. This case suggests that sweet itch combined with systemic corticosteroid treatment, mayact as predisposing factor for dermatophyte infection. In addition, the importance of correctisolation and identification of the causal agent is highlighted.

Author(s): 
R. VAN DYCK, C. FINA, E. BURESOVA, D. PAEPE, H. DE WILDE, S. DAMINET
Abstract: 
In this report, a dog is described that was referred to the Small Animal Department, Faculty of Veterinary Medicine (Ghent University) for further work-up and treatment of a solitary renal cyst. The cyst was treated successfully with ultrasound-guided drainage and percutaneous sclerotherapy. The dog was followed-up during twenty-four months post procedure with renal sonography. The complaints of intermittent lethargy disappeared after the first treatment. The ultrasonographic appearance of the cyst evolved from a round, anechoic, sharply demarcated lesion to an ill-defined, hyperechoic lesion.

Title: 
Peripheral osteoma of the mandible in a cat
Author(s): 
J. VAN DUIJL, J.N. WINER, H. DE ROOSTER, B. ARZI
Abstract: 
A six-year-old, male, castrated domestic shorthair cat was presented for evaluation of an oralmass. Full physical examination revealed a large hard mass arising from the lateral aspect ofthe caudal part of the left mandible. Abdominal ultrasound and thoracic computed tomography(CT) were performed to rule out metastatic disease. In addition, CT of the skull with intravenouscontrast agent was performed. Histopathological examination of extra-oral biopsies confirmedthe tentative diagnosis of peripheral osteoma. A three-dimensional printed skull was used inconjunction with the CT images to determine the detailed location and extent of the mass andto identify anatomical spatial relationships with important neurovascular structures. Surgicaldebulking of the osteoma was performed. The cat recovered uneventfully but the mass regrewnine months after debulking therapy, sooner than expected. Nevertheless, CT scan of the skullwas suggestive for regrowth of the peripheral osteoma rather than for malignant transformation.The owners did not elect to pursue caudal mandibulectomy.

Title: 
Intratumoral chemotherapy in an integumentary squamous cell carcinoma in a cockatiel (Nymphicus hollandicus)
Author(s): 
N. VAN HECKE, A. MARTEL, A. GARMYN, I. VAN DE MAELE, T. HELLEBUYCK, S. CROUBELS, R. DUCATELLE, G. ANTONISSEN
Abstract: 
An eight-year-old, female cockatiel (Nymphicus hollandicus) was presented with anorexia,lethargy, a mass at the lower side of the wing and discoloration of the feathers. Physical examinationshowed an ulcerated nodular integumentary lesion of approximately 4 cm³ ventromedial on thewing at the side of the propatagium and the humerus. Lateral and ventrodorsal radiographsrevealed only hepatomegaly. After a stabilization period, surgical excision of the tumor wasperformed. Based on histopathological evaluation and bacterial culture of the surgically removedtissue, the lesion was typed as an integumentary squamous cell carcinoma with secondarybacterial infection (Corynebacterium sp). Four weeks postoperative, the tumor had recurred.Chemotherapeutic treatment was started with intratumoral carboplatin (1.5 mg/cm³) once aweek. Because of further tumor growth after the second administration of carboplatin, resectionof the mass was performed before the next infiltration. However, the bird died during anesthesia.Despite increase in tumor size, histopathological and immunohistochemical evaluations showeddegeneration of the tumor with intercellular edema and vacuolization of the tumor cells,presumably resulting from carboplatin administration. More research is needed to investigatethe efficacy and safety of the intratumoral administration of carboplatin as a treatment option inbirds with integumentary squamous cell carcinoma.

Abstract: 
A four-year-old male castrated German shepherd dog was presented with severe left frontleg lameness due to a fibrosarcoma lateral to the elbow. The ill-defined mass was not amendableto wide local excision and a curative-intent limb amputation was performed. Immediately postoperatively,closed incision management with negative pressure wound therapy (NPWT) wasapplied to minimize the risk of postoperative complications. The incision line was covered witha PrevenaTM dressing attached to a NPWT pump set at a continuous negative pressure of -125mmHg. The dressing was removed 72 hours later. No wound complications were evident andfurther healing was unremarkable.

Title: 
Osteosynthesis of a mid-diaphysis femoral fracture by using a type I tie-in fixator in a kookaburra (Dacelo novaeguineae)
Author(s): 
L. GEERINCKX, T. VERBEEK, T. HELLEBUYCK
Abstract: 
In this case report, the successful management of a traumatic fracture of the femur in a kookaburrausing a type I tie-in-fixator (TIF) is described.A domesticated, five-month-old kookaburra (Dacelo novaeguineae) suffered trauma due to interspeciesaggression. Clinical and radiographic examination showed a closed, multiple transverse, spiralfemoral fracture, located in the mid-diaphysis. Reduction of the fracture was managed using a type ITIF, combining an intra-medullar (IM) pin in combination with an external skeletal fixator. Postoperativeradiographs confirmed an optimal reduction of the fracture and a correct placement of the type ITIF. Recovery was uneventful and correct positioning and normal functioning of the leg were observedimmediately following surgery. One week postoperatively, the bird removed the external fixation butthis did not interfere with the acquired stability and positioning of the affected leg. Two weeks after thesurgery, radiographs confirmed a good healing of the fracture as callus development and bridging ofthe cortices were present. Based on the clinical and radiographic findings, it was decided to remove theIM pin. During a three-month follow-up period, the kookaburra showed full recovery.

Author(s): 
R. SALGÜERO, I.N. PLESSAS
Abstract: 
A four-month-old English bulldog presented with an acute onset of facial twitching, headtilt and abnormal mentation. Neurological examination was consistent with a multifocal brainlesion. Hematology and biochemistry were unremarkable and MR imaging of the brain revealedmarked enlargement of the left lateral ventricle with associated calvarial enlargement andperiventricular T2W and fluid-attenuated inversion recovery (FLAIR) lesions with moderatecontrast enhancement. Cerebrospinal fluid (CSF) analysis revealed a moderate mixedmononuclear pleocytosis and infectious disease testing returned negative. The diagnosis of leftunilateral internal hydrocephalus and presumed periventricular encephalitis was made. Thepatient was treated with prednisolone and phenobarbitone with successful outcome despitethe poor prognosis. This is the first report of unilateral hydrocephalus and periventricularencephalitis with MR imaging in a dog.

Abstract: 
In this case report, a probable diagnosis of a rare endocrine condition in a cat is described. Aseven-year-old, spayed domestic shorthair presented with lethargy, partial anorexia and postprandialhypersalivation. A decreased activity level and a poor quality haircoat with excessive hair loss haddeveloped over the past six months. A probable diagnosis of acquired hypothyroidism was made afterexclusion of non-thyroidal diseases, decreased serum TT4 and serum fT4 levels and a positive responseto a therapeutic trial with levothyroxine. Nearly two years after the initial diagnosis, the cat was doingwell and was completely free of symptoms.
