Computed tomographic findings in two patients with vascular hamartomas

Area of Science:

• Radiology
• Pathology
• Oncology

Background:

• Vascular hamartomas are benign vascular tumors.
• Computed tomographic (CT) imaging is frequently used for diagnosis.
• Histopathological analysis is essential for definitive diagnosis.

Observation:

• Two cases of vascular hamartomas with distinct CT appearances are presented.
• Despite both lesions being histologically benign, one exhibited a disorganized architecture and aggressive clinical behavior.
• CT findings in the aggressive case mirrored the histological disorganization, potentially mimicking malignancy.

Findings:

• CT appearances of vascular hamartomas can be highly variable.
• Histological disorganization correlates with more aggressive clinical presentation.
• CT findings alone may be misleading without clinical and histological context.

Implications:

• Accurate diagnosis of vascular hamartomas requires a multidisciplinary approach.
• Radiologists and pathologists must consider all available data to avoid misinterpreting benign lesions as malignant.
• Understanding the diverse imaging spectrum of vascular hamartomas improves patient management.
