Abstract
Objectives : The primary objective of this case report is to review the clinical presentation, diagnostic methods, treatment, and outcomes associated with cavernous hemangioma of the urinary bladder. We aim to enhance awareness among healthcare professionals regarding this rare entity and improve management strategies for similar cases.
Introduction : Cavernous hemangioma of the urinary bladder is a rare vascular tumor that arises from the proliferation of blood vessels. While it can occur in various anatomical locations, its incidence in the bladder is particularly low, accounting for approximately 0.6% of urinary bladder tumors, with painless hematuria being the most common presenting symptom. The most frequent locations in the bladder are the base, posterior wall, and trigone. This condition presents diagnostic challenges due to its nonspecific symptoms, which often overlap with more common urological disorders. Cavernous hemangiomas are typically found in organs such as the liver, skin, or brain, where they are usually asymptomatic unless their size or location causes symptoms. Complete surgical excision is generally curative. Methods : A comprehensive literature review was conducted, focusing on case reports and studies published in peer-reviewed journals. The review iden
tified several cases of cavernous hemangioma, most commonly presenting with hematuria, urinary frequency, and pelvic pain. Imaging modalities such as ultrasound and CT scans revealed heterogeneous masses, often leading to differential diagnoses. Surgical excision emerged as the predominant treatment method.
Results : Most patients experienced favorable outcomes with no recurrence during follow-up.
Conclusion : Cavernous hemangioma of the urinary bladder, although rare, should be considered in the differential diagnosis of bladder masses, particularly in patients presenting with unexplained hematuria. Early diagnosis and appropriate surgical intervention lead to excellent long-term outcomes. Increased awareness and further research are essential to refine management protocols and improve patient care.

CASE PRESENTATION
Background
Cavernous hemangioma of the urinary bladder requires treatment with complete resection [1-4]. This case highlights the clinical course of a cavernous hemangioma and aims to enhance awareness among healthcare professionals regarding this rare condition and its management.
Case Report
We report the case of a 27-year-old male patient who presented with recurrent episodes of painless hematuria. The patient had no associated lower urinary tract symptoms. Urinalysis revealed significant microscopic hematuria. Imaging studies, including ultrasound of the kidneys, ureters, and bladder (KUB ultrasound), revealed multiple cavernous hemangiomas in the urinary bladder.
The bladder appeared well-distended with normal wall thickness, except for multiple echogenic lesions arising from the right lateral bladder wall. These lesions were well-circumscribed, hypoechoic, and heterogeneous, with no significant shadowing. The largest lesion measured approximately 2.5 cm × 2.0 cm. Color Doppler imaging showed minimal vascularity within the lesions. A diagnostic cystoscopy was recommended for further evaluation and correlation with clinical findings.
Intervention
A diagnostic cystoscopy revealed four sessile, red, cystic lesions on the right lateral wall of the bladder (Figures 1, 2). Resection of these masses was performed with deep resection into the muscle layer and fulguration of the base (Figures 3).

Histopathology
Macroscopically
• The masses were well-circumscribed, soft, and reddish-purple. The cut surface showed spongy areas with blood-filled spaces. No evidence of necrosis or calcification was observed.
Microscopically
• The sections showed a well-circumscribed lesion composed of large, dilated vascular channels lined by a single layer of flattened endothelial cells. The vascular spaces were separated by thin fibrous septa with minimal surrounding stroma. No cytologic atypia, mitotic activity, or evidence of malignancy was observed. The lumen of the vascular spaces contained red blood cells. There was no invasion into the surrounding deep or muscle layers.
Final Diagnosis
Cavernous hemangioma: A benign vascular lesion characterized by dilated, blood-filled spaces lined by endothelial cells. No evidence of malignancy.
Follow-Up
Three months postoperatively, ultrasound showed no evidence of recurrence. Diagnostic cystoscopy performed at three and nine months postoperatively also showed no recurrence of the lesions.
CONCLUSION AND DISCUSSION
This case emphasizes the importance of considering cavernous hemangioma in the differential diagnosis of hematuria. It highlights the effectiveness of endoscopic resection in managing this rare condition. Regular follow-up is essential to monitor for recurrence. Increased awareness among clinicians is vital for early diagnosis and optimal management.
