Summary
Isolated iliac artery aneurysms are rare vascular conditions. Unexplained hydronephrosis warrants pelvic imaging for early diagnosis of these concealed aneurysms.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Radiology
Background:
- Isolated iliac artery aneurysms (IIAAs) are rare, constituting 1% of intra-abdominal aneurysms.
- Their pelvic location often conceals symptoms, delaying diagnosis.
- Early detection is crucial to prevent rupture.
Observation:
- Three cases of IIAA are presented with their clinical and radiological features.
- Ultrasound initially identified ipsilateral hydronephrosis in all cases.
- Pelvic imaging confirmed the diagnosis in each instance.
Findings:
- IIAAs present unique diagnostic challenges due to their hidden anatomical position.
- Ipsilateral hydronephrosis is a significant indicator of underlying IIAA.
- Systematic pelvic imaging is essential when hydronephrosis is unexplained.
Implications:
- Increased awareness of IIAA clinical and radiological signs can improve diagnostic rates.
- Pelvic imaging should be considered in the workup of all unexplained hydronephrosis cases.
- Prompt diagnosis and treatment of IIAAs can avert life-threatening complications.
