Abstract

Case series summary: Two cats were initially evaluated for recurrent dysuria and haematuria, which were unresponsive to antibiotic and anti-inflammatory treatments. An abdominal ultrasound revealed focal wall thickening with a severe hypoechoic multicystic parietal lesion at the bladder apex. Surgical excision of the lesion (apical cystectomy) led to complete resolution of the clinical signs in both cases. The histological findings were consistent with large cystic von Brunn's nest hyperplasia, along with foci of small glandular metaplasia. Urine and tissue cultures were negative. Cystitis cystica was diagnosed. No recurrence was reported within 2 years of surgery in both cases.

Relevance and novel information: This case series illustrates the occurrence and ultrasonographic features of a type of cystitis rarely described in animals: cystic cystitis with von Brunn's nest hyperplasia. These lesions result from chronic irritation and can lead to recurrent cystitis if not excised. Cystic cystitis has previously been described histologically in cats. To the authors' knowledge, this is the first report of macroscopic apical cystic cystitis with pre-treatment ultrasound diagnosis. Surgical resection of the hyperplastic von Brunn's nests appeared to be curative in both cases.

两只猫的囊性膀胱炎伴冯布伦氏窝的超声诊断。
病例系列总结:两只猫最初被评估为复发性排尿困难和血尿,对抗生素和抗炎治疗无反应。腹部超声显示局灶性壁增厚,膀胱顶端有严重的低回声多囊性病变。手术切除病变(根尖膀胱切除术)导致两例临床症状的完全解决。组织学表现与大囊性冯氏巢增生一致,伴小腺体化生灶。尿液和组织培养均为阴性。诊断为囊性膀胱炎。两例患者术后2年内均无复发。相关性和新信息:本病例系列说明了一种很少在动物中描述的膀胱炎的发生和超声特征:囊性膀胱炎伴冯布伦巢增生。这些病变是由慢性刺激引起的,如果不切除,可导致复发性膀胱炎。以前在猫的组织学上描述过囊性膀胱炎。据作者所知,这是第一例术前超声诊断的宏观根尖性囊性膀胱炎。手术切除增生的冯·布伦氏窝在这两个病例中似乎是治愈的。
