A 25-year-old female macaroni penguin (Eudyptes chrysolophus) was diagnosed with exophthalmos secondary to retrobulbar neoplasia through use of computed tomography (CT). Histopathologic examination of the mass supported a diagnosis of malignant round cell neoplasia. Immunohistochemical (IHC) labeling was applied to determine cell origin; the neoplastic cells did not label with T-cell marker CD3 or B-cell marker BLA.36 and could not be further characterized. The scleral ossicles precluded evaluation of the retrobulbar space by ultrasonography; therefore, CT scanning is recommended for examination of intraorbital structures in penguin and other avian species. © 2015 by the Association of Avian Veterinarians.

Abstract: Two distressed Florida manatees (Trichechus manatus latirostris) were reported to the Florida Fish and Wildlife Conservation Commission. The first animal was determined to be an abandoned, emaciated calf. The second animal was a nursing calf that had sustained watercraft-related trauma. Both animals were captured and transported to Tampa's Lowry Park Zoo, where diagnostic evaluations, including physical examinations, blood work, computed tomography (CT), and radiographs were performed. Radiograph and CT scans identified the presence of free air within the pleural and abdominal cavities of both animals. Based on the lack of substantial findings in the first animal and a rapid resolution of clinical signs in the second animal, both animals were managed conservatively. This report documents simultaneous pneumothorax and pneumoperitoneum, the associated clinical and diagnostic findings, and conservative medical management of these conditions in the Florida manatee. © 2013 American Association of Zoo Veterinarians.

Lung lobe torsion is a rare pulmonary disorder in small animals and in humans. Torsion occurs when the lung lobe rotates around the bronchus and vascular supply and remains in that position. Lung lobe torsion is a life-threatening condition. The patient may present in an acute, fulminant respiratory crisis; however, more subtle clinical signs have also been reported. Lung lobe torsion may be secondary to an underlying pathology or spontaneous and idiopathic. Surgical resection of the affected lung lobe is the treatment of choice. The prognosis depends on the underlying cause. This article reviews the incidence, pathophysiology, clinical signs, diagnostic approach, and treatment of lung lobe torsion in dogs and cats.

Background: The utility of whole body magnetic resonance imaging (MRI) in detecting bone marrow infiltration in dogs with cancer has not been investigated. Objectives: To assess the feasibility of 3T body MRI for bone marrow assessment in dogs with hematopoietic neoplasia. Animals: Seven dogs with B-cell lymphoma, 3 dogs with myelodysplastic syndrome (MDS), and 2 clinically normal dogs. Methods: A prospective study of dogs with hematopoetic cancer was conducted using T1W, T2W, In-Phase, Out-of-Phase and STIR pulse sequences of the body excluding the head prior to bone marrow sampling. The relative signal intensity of a midlumbar vertebral body and a midshaft femoral bone marrow was compared by visual and point region of interest analysis to regional skeletal muscle. Results: Similarity of femoral diaphyseal and vertebral body marrow signal intensity to that of skeletal muscle on the Out-of-Phase sequence was useful in distinguishing the 3 dogs with hypercellular marrow because of MDS from the 7 dogs with B-cell lymphoma and from the 2 clinically normal dogs. 1/7 dogs with lymphoma had proven bone marrow involvement but normal cellularity and less than 5% abnormal cells. Unaffected midfemoral marrow had greater signal intensity than skeletal muscle and unaffected vertebral marrow had less signal intensity than skeletal muscle on the Out-of-Phase sequence. Conclusions and Clinical Importance: 3T, Out-of-Phase MR pulse sequence was useful in distinguishing diffuse bone marrow infiltrate (MDS) from minimally or unaffected marrow using skeletal muscle for signal intensity comparison on whole body MRI. © 2013 by the American College of Veterinary Internal Medicine.

Objective: To report the use of an axial pattern flap based on the cranial cutaneous branch of the saphenous artery to close a skin defect left on the medial crus after mast cell tumour removal. Case report: A seven-year-old, 32.41 kg, neutered male mixed-breed dog had a mast cell tumour incompletely excised from the left medial crus. The resulting 6 cm linear scar was excised with 2 cm wide margins and one fascial plane for deep margins. An axial pattern skin flap incorporating the cranial cutaneous branch of the saphenous artery was used to close the resultant skin defect. Results: The histopathology report documented clean margins and the flap survived completely. A seroma developed postoperatively, however it resolved without treatment. Clinical significance: An axial pattern skin flap based on the cranial cutaneous branch of the saphenous artery is a viable option for closing medial crus skin defects in the dog. © Schattauer 2011.
