Summary
Orbital lobular capillary hemangioma, a rare vascular tumor, was diagnosed in a 44-year-old man. Imaging revealed a distinct orbital mass, confirmed histopathologically as this specific hemangioma subtype.
Area of Science:
- Ophthalmology
- Radiology
- Pathology
Background:
- Orbital masses can present diagnostic challenges, requiring advanced imaging techniques.
- Lobular capillary hemangioma is a benign vascular tumor typically found in the skin and oral mucosa.
Observation:
- A 44-year-old male presented with a right orbital foreign body history.
- Computed tomography (CT) identified a well-enhanced orbital mass with specific characteristics.
- Magnetic resonance imaging (MRI) demonstrated characteristic signal intensities on T2-weighted and diffusion-weighted images.
Findings:
- Histopathological examination confirmed the orbital mass as a lobular capillary hemangioma.
- This represents the first reported case of orbital lobular capillary hemangioma with detailed imaging findings.
Implications:
- Accurate radiological diagnosis of orbital lobular capillary hemangioma is crucial for appropriate management.
- This case expands the known clinical and radiological spectrum of orbital tumors.
- Highlights the importance of considering rare diagnoses in orbital imaging evaluations.
