ABSTRACT
An 11-year-old, male castrated English springer spaniel was presented for muscle weakness, lethargy and anorexia while undergoing treatment of Stage IV lymphoma. Persistent hypokalemia prompted multiple diagnostic tests. Serum aldosterone levels, surgical exploration and histopathology confirmed primary hyperaldosteronism. Hyperaldosteronism is a rarely reported endocrinopathy in the dog. This report describes a case in which immunohistochemistry was utilized to confirm the diagnosis of an aldosterone-secreting tumour.

A five-year-old, spayed female mixed breed (38 kg) dog was referred for total hip replacement for an intermittently non-weight bearing lameness of the left hind limb. Radiographs and computed tomography suggested proliferative, osteolytic pathology of the left coxofemoral joint. Using arthroscopic exploration and biopsy, septic arthritis and osteomyelitis in the left coxofemoral joint were diagnosed. Treatment recommendations for antibiotic therapy and femoral head and neck excision were made based upon this diagnosis. Femoral head and neck excision resulted in pain relief and improved function and arthroscopy provided a minimally invasive, yet accurate, diagnosis in this case.

A seven-year-old neutered female golden retriever was presented for an acute onset of cervical pain and ataxia. Intervertebral disc disease or neoplasia was suspected. There was no evidence of a soft tissue or bony mass on physical examination or survey radiographs. Cerebrospinal fluid analysis did not show any evidence of a neoplastic process. Myelographic evaluation identified an extradural mass lesion extending from inside the calvarium to the mid-body of the first cervical vertebra. No additional diagnostic tests were performed as the owners elected for euthanasia because of the high possibility of a neoplastic process with an accompanying poor prognosis. Multilobular tumour of bone was diagnosed on postmortem examination.

Osteochondrosis lesions in the tibiotarsal joint were treated arthroscopically in two dogs. One dog had unilateral osteochondrosis of the dorsal aspect of the lateral trochlear ridge of the talus. The second dog had bilateral osteochondrosis of the plantar aspect of the medial trochlear ridge of the talus. Removal of all osteochondral fragments (i.e., joint mice) and debridement and curettage of the remaining talar defects were accomplished arthroscopically. Both dogs had excellent short-term outcomes.
