Identification and prevalence of errors affecting the quality of radiographs submitted to Australian thoroughbred yearling sale repositories.

We aimed to identify common mistakes made when radiographing yearling sale horses. Radiographic examinations from repositories at eight yearling sales held in Australia in 2003 were assessed by one of four veterinary radiology specialists. Each radiographic examination consisted of a maximum of 34 radiographs.

Lymphangiosarcoma in two cats.

Lymphangiosarcoma is a malignant neoplasm of the lymphatic endothelium that is rare in cats. This report describes two cases of feline lymphangiosarcoma that originated in the distal limb, causing intractable lymphoedema and serosanguineous discharge with ecchymoses in local and distant sites. In association with the neoplasia, one cat had cortical bone lysis of multiple metacarpal bones of the affected limb and the other had severe immune-mediated haemolytic anaemia (IMHA).

Evaluation of lymphoma in a cat using 99mTc-sestamibi.

This report describes the evaluation of cutaneous lymphoma in a cat using 99mTc-sestamibi. A mass in the left pes with extension to the left popliteal lymph node was diagnosed as B-cell lymphoma. Thoracic and abdominal radiography and abdominal ultrasound were unremarkable.

Imaging diagnosis: pneumothorax and focal peritonitis in a dog due to migration of an inhaled grass awn.

A 1-year-old working Kelpie developed pneumothorax and focal peritonitis after inhalation of a grass awn that migrated from the lung, through the diaphragm, into the peritoneal cavity. Radiographic evidence of sternal lymph node enlargement was fundamental in the diagnosis of intraperitoneal disease and prompted abdominal ultrasound leading to definitive diagnosis.

High field strength (4.7T) magnetic resonance imaging of hydrocephalus in an African Grey parrot (Psittacus erithacus).

Hydrocephalus was diagnosed in a juvenile African Grey parrot by high-field strength (4.7-Tesla) magnetic resonance imaging (MRI). Excellent anatomic detail was achieved, and there was severe dilation of all ventricles.
