Orbital dermoid diagnosed by computed tomographic scanning
American Journal of Ophthalmology
|January 1, 1978
Summary
A computed tomography scan identified an orbital mass containing fat in a young man. Surgical examination confirmed it to be an oil cyst type of dermoid cyst.
Area of Science:
- Ophthalmology
- Radiology
- Pathology
Background:
- Orbital masses can present with varied imaging characteristics.
- Lacrimal gland fossa is a common site for orbital tumors.
Observation:
- Computed tomography (CT) revealed a low-density orbital mass in the lacrimal gland fossa of a 20-year-old male patient.
- The low attenuation values (below water density) suggested a fat-containing lesion.
Findings:
- Surgical exploration confirmed the orbital mass to be a dermoid cyst.
- Specifically, it was identified as the oil cyst subtype of dermoid cyst.
Implications:
- This case highlights the importance of CT in characterizing orbital masses.
- Accurate preoperative diagnosis aids in surgical planning and management of orbital tumors.
- Dermoid cysts, particularly the oil cyst type, should be considered in the differential diagnosis of fat-containing orbital lesions.
