Pituitary macroadenomas are large tumors of the pituitary gland that are either functional (secrete hormones) or non-functional (do not secrete hormones). The most common functional pituitary macroadenoma in the dog secretes the hormone ACTH, causing increased cortisol levels and Cushing’s disease. Non-functional macroadenomas cause clinical signs through compression of nearby structures resulting in vision changes, diabetes insipidus, and neurologic disorders. This handout explains the effects of these tumors on dogs, how they are diagnosed, and the treatment options available.

Plasma cell tumors develop as a result of dysregulated production of plasma cells and are relatively uncommon in dogs and cats. Some plasma cell tumors are benign and the most common locations for these tumors are the head, feet, lips, mouth, and ears. The treatment of choice for benign plasma cell tumors is surgical removal, with little to no recurrence if completely excised. Conversely, multiple myeloma is a very malignant cancer that is usually treated with chemotherapy.

Pleural effusion refers to the abnormal accumulation of fluid within the chest cavity. The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. There are several causes, including chylothorax, heart failure, and lung or chest tumors. Dogs presenting for pleural effusion are often experiencing shortness of breath and decreased oxygen intake; placing them into an oxygen cage provides some degree of immediate relief. Removing the fluid that surrounds the lungs will allow the dog to breathe more readily and this fluid can then be tested to identify the cause of the pleural effusion. The treatment and prognosis vary depending on the underlying cause.
