Plain-English summary
A 6-year-old female cat suddenly collapsed and was found to have severe anemia and a large mass in her abdomen. After surgery, the vet discovered a large cyst filled with blood in her reproductive system. The cat underwent an ovariohysterectomy (spay surgery) to remove the affected area, and she made a full recovery. This case highlights a rare condition called hematosalpinx, where blood accumulates in the fallopian tube, which has mostly been seen in humans before this.

Abstract
A 6‐year‐old, intact female cat presented with sudden collapse. Clinical examinations indicated severe regenerative anemia and a large abdominal mass containing fluid. An exploratory laparotomy revealed a large cystic lesion at the cranial end of the right uterine horn. Ovariohysterectomy was performed, and the cat made a full recovery. The cystic lesion contained a blood clot and 102 mL of blood. Histological examination confirmed that the hemorrhagic lesion was located within the fallopian tube. The thickened uterus with severe vasodilation was histologically diagnosed as endometrial hyperplasia with congestion. This is the first reported case of hematosalpinx in a cat, a rare condition previously described in humans.
