摘要:

A wide variety of normal and pathologic factors may induce intraabdominal calcification. In general, the most reliable indication of the cause of a calcification is its location; therefore, if the affected organ can be identified the radiographic diagnosis is often straightforward or, at least, limited to relatively few possibilities. With this principle in mind, a series of patients with abdominal calcification are described for the purpose of illustrating the appearance of calcification of various abdominal organs. In addition, etiology for the calcification in each patient is discussed. Certain extraabdominal calcifications which may be seen on abdominal radiographs are also mentioned.

摘要:

Primary tumors of the larynx or trachea are uncommon in the dog and cat. In a review of the English language literature, description of 65 such patients were found. In a search of the Veterinary Teaching Hospitals of the University of Pennsylvania and North Carolina State University, an additional 13 previously unreported patients were identified, bringing the total to at least 78. Of these 78, there have been 16 canine tracheal, 7 feline tracheal, 34 canine laryngeal and 21 feline laryngeal tumors. In the canine and feline trachea, osteochondroma and epithelial malignancies, respectively, appear to be the most common. Epithelial malignancies appear to be the most common tumor of the canine larynx whereas lymphosarcoma appears to be the most common feline laryngeal tumor. In patients described herein, tumors produced clinical signs consistent with airway obstruction. Voice alteration was common in patients with laryngeal tumors. Patients were middle‐aged to older, except for dogs with osteochondroma. This compares favorably to historical data. All tumors in this study were readily seen radiographically, with most laryngeal and tracheal tumors appearing as masses within the lumen of the airway. Mineralization was uncommon except for canine osteochondromas. Feline laryngeal tumors in this study appeared as generalized laryngeal thickening rather than as a distinct mass. Response of canine and feline tracheal and laryngeal thickening rather than as a distinct mass. Response of canine and feline tracheal and laryngeal tumors to treatment can not be adequately assessed from available data. Benign tumors of the larynx or trachea may be amenable to complete excision. Neoplastic lesions must be differentiated from polyps or abscesses within the upper airway as these may appear radiographically identical to primary tumors. This can be achieved by endoscopic evaluation and biopsy of airway masses before formulating a prognosi

摘要:

Radiographs of 19 dogs diagnosed as having malignant histiocytosis were examined. The most common abnormalities involved the spleen (10), liver (6), lymph nodes (6 thoracic, 4 abdominal), and lungs (6). Other abnormalities involved the spinal column (3), and bones (2). Correlations were made between radiographic appearance and histologic diagnoses. As has been reported, Bernese Mountain Dogs were found to be significantly more often affected than other breeds. Rottweilers and Golden Retrievers were also found to have higher incidence rates. Viewed radiographically, treatment appeared to have little impact on the course of the disease.

摘要:

The ultrasonographic and medical records of 26 dogs examined for testicular/scrotal abnormalities were reviewed. Fifteen dogs were diagnosed with testicular neoplasia that included one or more of the following tumor cell types: Sertoli cell, seminoma and interstitial cell. Ultrasound was highly sensitive to detection of testicular neoplasia including one nonpalpable tumor. Tumor type specificity was not readily apparent in this study, although the three nondescended Sertoli cell tumors displayed similar characteristic sonographic patterns. Six dogs were reviewed with nonneoplastic, noninfectious disorders that included: vascular compromise, atrophy, scrotal edema and intestinal hernia. Five dogs with infectious diseases were reviewed. Ultrasound was sensitive and relatively specific for the nonneoplastic conditions.

摘要:

Soft tissue‐ and bone‐phase scintigrams were acquired from 4 normal horses before and over a 14‐day period after metacarpophalangeal, antebrachiocarpal, tarsocrural and tarsometatarsal joint blocks. Images were evaluated subjectively and quantitatively for increased activity in these regions. The antebrachiocarpal block resulted in obvious focal accumulation of activity on soft tissue‐phase scintigrams. This increased activity was greatest 2 to 4 days postanesthesia and persisted up to 14 days postanesthesia. On quantitative analysis of soft tissue‐phase images, similar trends were noted after the metacarpophalangeal and tarsocrural blocks, but these increases were relatively mild and were not evident on subjective evaluation of the images. Abnormal soft tissue‐phase activity was not associated with the tarsometatarsal block. On bone‐phase scintigrams, increased activity was not present following any of these

摘要:

An 18‐month‐old pregnant heifer, hitherto normal, was noticed to regurgitate wet, partially digested roughage several times a day. On clinical examination, the heifer was losing body weight. There was no obstacle to passing a stomach tube to the rumen. A barium study of the esophagus was performed. Megaesophagus involving the cervical and cranial thoracic esophagus was diagnosed. Postmortem findings were a dilated esophagus, with no gross pathology seen. Histopathology showed extensive submucosal cellular infiltration of eosinophils. The classification and possible etilogy of the case is discus

摘要:

A 4‐year‐old cat was presented for polyuria and polydipsia. Unilateral hydronephorosis and hydroureter was diagnosed on ultrasound examination of the abdomen, and right ureteral calculi were seen in survey abdominal radiographs. Intravenous urography confirmed hydronephrosis and indicated poor renal funttion in the right kidney. Surgical removal of the ureteral calculus improved right renal function. Analysis of the calculus indicated composition of calcium oxalate, an uncommon calculus in c
