CASE 2 – Nutritional secondary hyperparathyroidism

Leave a Comment

History:

 

difficulty walking, abnormal conformation Technique: X-ray Findings: There is a generalized reduction in radiopacity of bones (diffuse osteopenia). The cortices of bones are thinned. Coarse trabeculation visible especially in the pelvis. Folding fracture seen in the left scapula. Excessive curvature of the spine. The vertebral body of L4 its shorter and the sacrum has an abnormal curvature, which means folding fractures at this levels. Abnormal alignment of the sternum.

Nutritional secondary hyperparathyroidism

 

Discussion:

 

Nutritional secondary hyperparathyroidism is seen in young growing animals, particularly kittens, fed a high-meat diet which is low in calcium and high in phosphorus.

Imaging – Case 1

10 years old Golden Retriever

History:  chronic right inner ear infection

Technique: X-ray, MRI

Findings:

X-rays: There is thickening and destruction of the right tympanic bullae.
There is marked swelling of the soft tissues of the right aural region. The external ear canal is obliterated and there is calcification of its inner end.4321
MRI: There is a well-demarcated, expansile mass in the right tympanic bulla, with remodeling and destruction of the right tympanic bone. The right petrous temporal bone and the right inner ear are unclear indicating erosion from the mass. The right external ear canal is not visible. The muscles and tissues on the right side appear markedly hyperintense and there is a fluid filled cavity approximately 6 x 4.4 x 1.9 cm that appears to continue cranially and communicate with right tympanic bulla. This cavity extends from the level of the tympanic bulla and caudally up to the level of the C2 vertebra. The right mandibular salivary gland appears displaced medially from the cavitary lesion.sss

Conclusion:sss1

mass in the right tympanic bulla is consistent with cholesteatoma. Erosion of the right petrous temporal lobe and possible involvement of the inner ear is visible.
Cystic lesion may reflect abcess or haematoma.

Discussion:

Cholesteatoma, a destructive and expanding growth, in the middle ear and/or mastoid process, is a relatively rare cause of otitis media in dogs.
Cholesteatoma are epidermoid cysts lined by a pluristratified keratinizing epithelium containing keratin debris and is characterized by independent and progressive growth, causing destruction of adjacent tissue, especially bone.
