Lumps and Bumps Flashcards
What initial diagnostic technique would be most appropriate for a suspected hematoma on a bovine abdomen?
ultrasound
What diagnostic technique(s) would be most appropriate for a suspected abscess in the abdominal region?
Start with an ultrasound to make sure there are no bowel loops. Once confirmed, you can perform FNA of the fluid with a needle.
In a calf with a small swelling on the side of its face, what would be your approach in diagnosing the etiology?
stick a needle into it to see if pus comes out; if so, then lance and drain it.
A bull presents to you and he has a few lumps – one on his neck area and the other just caudal to his shoulder. What most likely are these lumps?
injection site reactions
A dairy cow presents with peripheral lymphadenopathy. What is the most likely diagnosis?
lymphoma
If adult cattle have masses around their jaw/mandible area, what is an important observation you must make in order to make a diagnosis?
you need to determine if the mass is originating from the area between the 2 mandibles or the jaw bone itself.
If from the jaw, its lumpy jaw = actinomyces bovis
if between the 2 mandibles, its wooden tongue = actinomyces lignieresii
what is the diagnostic approach / treatment for a bull with multiple cauliflower-like warts along his shoulder area?
these are most likely papillomas and can be plucked off if the base is small enough.
These warts are not harmful, but these animals cannot go to shows because this is contagious.
You are called to examine a bull with a round, ulcerated mass on his shoulder. You perform FNA and the fluid that you collected is gray. What is your diagnosis? What is the treatment?
melanoma
tx for this is to cut it out. these dont usually metastasize or cause problems in cattle.
How can you differentiate between waterbelly and acorn toxicosis?
acorn toxicosis leads to renal tubular necrosis and ventral edema which can appear very similar to waterbelly where urine is leaking out.
You should take an FNA of the area and place fluid on Azostick. If the BUN is high, it is waterbelly.
You should also check a blood sample to determine if the BUN is high. If the Blood BUN is normal, then the diagnosis is waterbelly. if the Blood BUN is low, then acorn toxicosis.
how can you differentiate a penile hematoma versus waterbelly?
A penile hematoma usually causes prolapse due to swelling, whereas waterbelly will not cause this prolapse.
how do you diagnose a mast cell tumor?
biopsy
sometimes FNA tho so idk
what is most likely the diagnosis of a small ruminant with a small focal mass on the side of the face, located near the peripheral lymph nodes?
Caseous lymphadenitis caused by Cornybacterium pseudotuberculosis
What condition light colored animals predisposed to forming?
squamous cell carcinoma.
