![]() The etiologic determination is unusual due to the cost implicated in laboratory tests and the restrictions in the availability of the advanced imaging techniques that are not yet available for veterinary diagnosis. ![]() ![]() In Medellín, in regular clinical practice, the clinical diagnosis of hyperadrenocorticism based usually in systemic and dermatologic signs is common. A functional pituitary tumor causing pituitary dependant hyperadrenocorticism (PDH) is the most common cause of canine hyperadrenocorticism (2, 7). Clinical signs in naturally occurring hyperadrenocorticism are the result of cortisol overproduction that may result from excess secretion of ACTH (2). Hyperadrenocorticism is a common clinical disorder, and is one of the most common endocrinophaties in dogs (1, 2). Key words: canine, Cushing, imaging, pituitary, tumor. This report describes the case of an eleven year-old golden retriever with PDH as a result of a functional pituitary tumor, visualized by magnetic resonance imaging using gadolinium as contrast agent. In Colombia, the use of these imaging techniques is very limited in the small animal practice, but it has recently become available for veterinary patients thanks to agreements with human clinical institutions. Moreover these imaging techniques are required to asses the size and location of the pituitary tumor when planning surgical removal of the tumor mass or of the complete pituitary gland. Advanced imaging techniques like computed tomography (CT) or magnetic resonance imaging (MRI) are the best means to obtain a diagnosis of a pituitary tumor in dogs with pituitary-dependent hyperadrenocorticism (PDH). Almost eighty five percent of the cases of spontaneous hyperadrenocorticism in dogs are the result of a functional pituitary tumor or hyperplasia. 1226, Medellín, ColombiaĢDocente Facultad de Ciencias Agrarias, Universidad de Antioquia, Medellín, 10 mayo, 2006 aceptado: 20 Octubre, 2006)Ĭushing’s disease is a common endocrine disorder of dogs, caused by persistent high concentration of cortisol in circulating blood.

This update aims to show the new evidence available and ensure the best scheme for prevention, diagnosis and management of adverse events intravascular contrast media.Pituitary tumor diagnosis using gadolinium-enhanced magnetic resonance imaging in a dog with hyperadrenocorticism. ![]() There is much heterogeneity in the management of adverse reactions, so there is the need to create a document that allows the radiologist, cardiologist or physician requesting the study, directed about the decisions taken against the possible problems They presented with the administration of contrast media. These adverse reactions may kidney such as the MC-induced nephropathy and kidney not as nausea, vomiting, feeling hot, headache, dizziness, altered taste, itching, pallor, redness etc. We found iodinated contrast media, barium and paramagnetic and like other drugs are not without side effects, which can occur in children, adults and pregnant women. The contrast media (CM) are substances used to enhance the differentiation between different tissues in medical imaging, to alter the response of some of them against electromagnetic radiation or ultrasound.
