Laparoscopic partial cystectomy for venous malformation of the bladder

Area of Science:

• Urology
• Vascular Anomalies
• Surgical Pathology

Background:

• Venous malformations (VMs) of the bladder are rare clinical entities.
• Misdiagnosis of bladder VM can occur due to overlapping symptoms and imaging findings with other conditions like endometriosis.

Observation:

• A patient presented with symptoms initially attributed to endometriosis, leading to misdiagnosis.
• Despite initial hormonal therapy failure and subsequent partial cystectomy, a residual vascularized lesion persisted.
• The patient remained asymptomatic with stable disease after 24 months of close follow-up.

Findings:

• Histopathological diagnosis confirmed a venous malformation after surgical intervention.
• Incomplete resection of the bladder VM was noted on follow-up cystoscopy.
• Long-term asymptomatic stability was achieved through conservative management post-incomplete resection.

Implications:

• This case underscores the need to consider venous malformations in the differential diagnosis of atypical urological symptoms.
• It highlights the potential for conservative management and observation in cases of incompletely resected bladder VMs.
• Accurate diagnosis and appropriate management strategies are crucial for improving patient outcomes in rare bladder lesions.
