Retroperitoneal hemangioma demonstrated on blood pool scan

Area of Science:

• Radiology
• Nuclear Medicine
• Oncology

Background:

• Retroperitoneal hemangiomas are uncommon vascular tumors.
• Accurate diagnosis can be challenging using conventional anatomical imaging alone.

Observation:

• An 80-year-old female patient with hypertension and diabetes presented with an abdominal mass.
• Initial diagnosis was made via CT abdomen and pelvis, with stability confirmed by MRI 16 months later.

Findings:

• Computed tomography (CT) and magnetic resonance imaging (MRI) provided initial characterization of the retroperitoneal mass.
• A technetium-99m labeled red blood cell scan definitively confirmed the diagnosis of hemangioma.

Implications:

• This case underscores the utility of multimodal imaging, including nuclear medicine, for diagnosing rare retroperitoneal masses.
• Integrating functional imaging like 99mTc-red cell studies can improve diagnostic certainty for vascular lesions.
• Early and accurate diagnosis of retroperitoneal hemangioma is crucial for appropriate patient management.
