Primary pulmonary osteosarcoma treated by thoracoscopy-assisted lung resection in a dog.

A 6-year-old female, intact boxer presented with acute respiratory distress due to a mass in the left cranial thorax. The tumor, which originated in the left lung and was shown by histology to be an osteosarcoma, was removed by lateral thoracotomy. The dog died from unrelated disease 7 mo later and no tumor was evident at necropsy.

Use of the distomedial-proximolateral oblique radiographic view of the elbow joint for examination of the medial coronoid process in dogs.

Objective: To describe and evaluate a new radiographic view of the elbow joint in dogs that would potentially enhance observation of the medial coronoid process (MCP).

Sample Population: 20 cadaver limbs from 10 dogs and clinical examination of 100 elbow joints of 53 dogs.

Procedure: Twenty elbow joints from 10 cadavers were imaged by use of mediolateral, flexed mediolateral, craniocaudal, craniolateral-caudomedial oblique (Cr15L-CdMO), and distomedial-proximolateral oblique (Di35M-PrLO) radiographic views before and after placement of 3 lead pellets placed on the cranial, medial, and craniodistal aspect of the MCP.
