Extraconal orbital lesions
Extraconal orbital lesions include lesions which arise from structures within the extraconal orbital space and those extending from adjacent structures into the orbits.
Differential diagnosis
Intraorbital lesions
- dermoid cyst: most common lesion in pediatrics
- lacrimial gland lesions
- dacryocystocoele
- capillary hemangioma
- cavernous hemangioma
- lymphangioma
- plexiform neurofibroma
- orbital pseudotumor
- Langerhans cell histiocytosis
- rhabdomyosaroma of the orbits
- lymphoma/leukemia
Extraorbital lesions extending into extraconal space
- infections
- mucocoele
- metastasis
- sinonasal tumors
- meningioma
