Multilobular Osteochondrosarcoma

112 years mix breed dog, F

 

History:  presented for a large firm mass arising from the right side of the calvarium.

 

Findings: A dense, mineralized mass with a stippled appearance arising from the right side of the calvarium, with an approximate diameter of 6cm.

Because of the dense appearance of the mass, it’s hard to appreciate the degree of underlying osteolysis just with an Xray

A CT scan was recommended to evaluate local  invasion.2(1)

 

Diagnostic: the radiological appearance it’s of MLTB (multilobular osteochondrosarcoma)

 

Discussion: MLTB is an uncommon tumour that arises almost exclusively on the flat bones of the skull, mainly on the calvarium, maxilla and mandible and tend to occur in older medium and large breed dogs, although they have been reported in younger and small breed dogs, and have also been reported in cats. It is slow-growing and locally invasive, often recurring after excision. Metastasis may occur

Case 3 – Ruptured urinary bladder with radiopaque calculi free in the peritoneal cavity.

9 years old mix breed dog, F

 

History: not urinating for 24hours, apathy, lethargy

 

Technique: X-ray

 

Findings: Loss of serosal detail especially in the ventral abdomen.

There are multiple radiopaque mineral foreign bodies of varying sizes in the ventral abdomen not included in the digestive tract.

The urinary bladder it’s only partially visible.imaging-1imag-2

 

Conclusion: ruptured urinary bladder with radiopaque calculi free in the peritoneal cavity.

Akira is a German shepherd dog, first presented with an ascites and exercise intolerance 4 years ago. A diagnosis of a tricuspid valve dysplasia (TVD) was made after X-rays and echocardiography. Standard therapy for a patient with a TVD and CHF was initiated and kept since. The prognosis given in 2012 was ‘guarded to poor’ concerning the severe generalized cardiomegaly, but four years later the patient is still alive and doing great with a full therapy (attached). The size of the heart is bigger at any of the control X-rays done annually; the size of the right atrium contributing with 75% to the whole heart volume!

CASE 2 – Nutritional secondary hyperparathyroidism

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.

 

Diagnostic:d290472b-3434-44ad-bf45-16d4233d9fb1c0793007-0eca-44cb-b0b5-e4b1a686da67

 

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.
