Most cysts can be felt by palpation just beneath the ribcage; they feel slightly bumpy and round, and will roll under your thumbs as you examine the pig. The usual symptoms are:
- Hormonal behaviour (excessive rumbling, mounting)
- Hair loss (the alopecia is frequently symmetrical on the sides of the belly)
- Swollen/enlarged/crusty nipples
- Swollen abdomen
I can't remember if an xray will show them, but an ultrasound certainly will. Ovarian cysts are commonly diagnosed as a kidney complaint, but the kidneys don't move under your thumbs as cysts do.
Treatment is preferably non-surgical -a hysterectomy is not usually necessary unless the cysts are causing other problems. Hormone treatment is the first port of call; 0.2ml HCG injected, and repeated after 4 weeks, usually shrinks cysts enough that they no longer pose a problem. If the cysts are excessively large, they can be drained by a needle inserted into the abdomen.
