RESUMO
We present the case of a five-year-old intact mixed breed male dog with hemorrhagic prostatic cysts. The patient presented with hematuria, dysesthesia, and pain on abdominal palpation. Abdominal ultrasound, hematology, urinalysis, and biochemical evaluation tests were subsequently conducted. Laboratory tests revealed cloudy urine with bacteria, and countless red blood cells. On ultrasound examination, the prostate was severely enlarged, with heterogeneous and reduced parenchyma, surrounding a large cavity filled with anechoic material with moderate cellularity. The urinary bladder was markedly distended and had a round, hypoechogenic structure in the lumen. The patient was hospitalized and had significant, irreversible worsening of the clinical symptoms and died. Subsequently, necropsy of the patient was performed and a histopathological diagnosis of benign prostatic hyperplasia associated with the presence of a prostatic hemorrhagic cyst, prostatitis, and chronic cystitis with an intraluminal blood clot was made. To the best of our knowledge, this is the first report to describe the occurrence of a hemorrhagic cyst in a canine prostate, thus bringing important information from clinical and imaging findings to the veterinary routine.
Apresentamos o caso de um cão macho de cinco anos de idade sem raça definida com cisto prostático hemorrágico. O paciente manifestava hematúria, disquesia e dor à palpação abdominal. Foram realizadas ultrassonografias abdominais subsequentes, hematologia, urinálise e testes de avaliação bioquímica. Os testes laboratoriais revelaram urina turva com bactérias e inúmeros glóbulos vermelhos. No exame ultrassonográfico, a próstata estava severamente aumentada, com parênquima heterogêneo e reduzido, circundando uma grande cavidade cheia de material anecoico com celularidade moderada. A bexiga urinária estava marcadamente distendida e tinha uma estrutura redonda e hipoecogênica no lúmen. O paciente foi internado e teve um agravamento significativo e irreversível dos sintomas clínicos e veio a óbito. Subsequentemente, foi realizada a necropsia do paciente e foi feito o diagnóstico histopatológico de hiperplasia prostática benigna associada à presença de um cisto hemorrágico prostático, prostatite e cistite crônica com um coágulo sanguíneo intraluminal. Tanto quanto sabemos, este é o primeiro relatório descrevendo a ocorrência de um cisto hemorrágico numa próstata canina, trazendo assim informações importantes dos resultados clínicos e de imagem para a rotina veterinária.
RESUMO
A 7-year-old male neutered, 6.5 kg, Maltese breed dog was referred with a history of dysuria after undergoing two cystotomies to remove calcium oxalate uroliths. Survey radiographs were inconclusive. Excretory urography allowed visualization of two filling defects in the cranioventral urinary bladder region. Ultrasonography showed urinary bladder sediments, a diffusely thickened wall, and two circumscribed intramural/intraluminal structures with an anechoic interior and a smooth and regular surface. The cystoscopic diagnosis was urinary bladder abscesses and urine cultures were positive for Escherichia coli. Antimicrobial/anti-inflammatory therapy was started with good clinical outcomes and negative culture after 21 days.
