Imaging in exotic species

Question 1

You perform an ultrasound via the pre-femoral fossa of a tortoise and this is the image that you obtain.

What is your diagnosis?

Answer 1

Pre-Ovulatory Follicular Stasis (POOS)

Question 2

In reptiles, metabolic bone disease is a common presenting and incidental finding on radiographs. If you were to radiograph a lizard, explain what part of a dorsoventral radiograph would help you diagnose this condition

Answer 2

Look at bone density, particularly the distal limbs.
If you cannot see the lizards digits and the settings are correct, this is diagnostic.
The spine and more central bones are only effected if incredibly severe.
Also look for bone shape deformities and evidence of pathological fractures.
