[99m-Technetium-pertechnetate- and 99m-Technetium-sestamibi-scintigraphy for visualization of hypofunctioning thyroid tissue and staging in a dog with thyroid carcinoma].

A 10-year-old female mixed breed dog was presented for thyroid scintigraphy due to a cervical mass. Apart from 99m-Technetium-pertechnetate (Tc-pertechnetate) scintigraphy, a second scintigraphy using 99m-Technetium sestamibi (Tc-MIBI) was performed because of additional hypothyroidism suspective for a "cold" nodule and as screening for metastases.Twenty minutes following intravenous injection of 38 MBq Tc-pertechnetate, a "hot" cervical as well as a "hot" intrathoracal nodule were seen with an uptake of 8.

[Urethrolithiasis in the dog - a retrospective evaluation of 83 male dogs].

Objective: Urethral calculi are a frequent cause of urinary disorders in male dogs. The aim of this study was to evaluate male dogs with urethral stones, which were relocated into the urinary bladder with the support of standardized epidural anesthesia in addition to general anesthesia.

Materials And Methods: Data of 83 male dogs with urethral calculi were evaluated regarding clinical signs, localization and number of urethral calculi, diagnostic imaging, surgical procedure and postoperative radiographs.

Inadvertent iatrogenic prostatectomy and urethrectomy in 2 dogs.

Two dogs were referred because of dysuria following inadvertent iatrogenic total prostatectomy and urethrectomy. In both cases an existing perineal hernia was not recognized by the referring veterinarians and the caudally herniated prostate gland was diagnosed as a perianal neoplasia and subsequently removed. Both dogs were treated with isolation of the urinary bladder from the urethra and a permanent prepubic cystostomy tube.

Measurement of the normal feline pituitary gland in brachycephalic and mesocephalic cats.

Objectives The purpose of this study was to determine differences in normal feline pituitary dimensions in brachycephalic and mesocephalic cats as a basis for establishing cryohypophysectomy in cats. Methods Measurements were performed on sagittal T2-weighted and transverse post-gadolinium T1-weighted or T1 3D fast field echo-weighted MRI images. A total of 32 brachycephalic and 27 mesocephalic cats were examined.

[Nasopharyngeal cyst of the respiratory epithelium in a 9-year-old Yorkshire terrier].

In a 9-year-old Yorkshire terrier a cyst of the respiratory epithelium of the nasopharynx was diagnosed. A complete obstruction of the nasopharynx leading to dyspnea was detected by computed tomography and endoscopy. A minimally invasive ablation of the cystic wall was performed under endoscopic guidance, followed by a pathohistological examination.

Clinical, radiographic, and magnetic resonance imaging findings of gastrocnemius musculotendinopathy in various dog breeds.

Objectives: To describe clinical, radiographic, and magnetic resonance imaging (MRI) findings in 16 dogs diagnosed with gastrocnemius musculotendinopathy.

Methods: Retrospective evaluation of medical records, radiographs, and MRI results, as well as follow-up completed by telephone questionnaire.

Results: Most dogs had chronic hindlimb lameness with no history of trauma or athletic activities.

[Complications and prognosis of cervical sialoceles in the dog using the lateral surgical approach].

Objective: Evaluation of intra- and postoperative complications and prognosis of cervical sialoceles in the dog when using the lateral surgical approach for extirpation of the mandibular and sublingual salivary glands.

Material And Methods: Medical records of 16 dogs with 19 sialoceles were evaluated retrospectively. Long-term follow-up was evaluated by telephone questionnaire to the owners or the referring veterinarian.

Extrahepatic biliary atresia in a 4-week-old Pug.

Objective: To report diagnosis and surgical therapy of extrahepatic biliary atresia in a dog.

Study Design: Clinical report.

Animal: Dog (n = 1).

Recurrent spinal arachnoid cyst in a cat.

Spinal arachnoid cysts (SACs) are uncommon expanding lesions in the spinal canal. They are rarely diagnosed in dogs, and there are only four published cases in cats. We report a case of a 12-year-old cat with recurrent signs of intermittent urinary incontinence and hind limb ataxia 2 years after surgical marsupialisation of a spinal arachnoid cyst at T11/12.
