A soft tissue mass in the inferior aspect of the orbit inseparable from inferior rectus muscle. The mass results in proptosis and deforms the posterior aspect of the globe.
2 case questions available
Q: What are the main differential diagnoses of the intra orbital lesion in a child? show answer
A: Dermoid cyst is the most common Vascular malformations including haemanioma, lymphangioma Optic nerve glioma - if bilateral most likely NF1 Inflammation (LCH) and infection Soft tissue malignancy: rhabdomyosarcoma
Q: What is the most common malignancy involving the orbits in children? and what is the most common imaging features? show answer
A: If globe is also included then retinoblastoma is the most common. However, the most common soft tissue orbital malignancy in childhood is rhabdomyosarcoma. Rhabdomyosarcoma of the orbits when small are relatively well defined but as they grow they become infiltrative soft tissue mass with variable enhancement and potentially erodes through the adjacent bones. Calcification is rare.
Case Discussion
CT of the orbits demonstrates a soft tissue mass in the inferior aspect of the orbit inseparable from inferior rectus muscle. The mass results in proptosis and deforms the posterior aspect of the globe.
The remainder of the orbit is unremarkable, and the contralateral orbit is normal. Findings are consistent with the histologically proven with orbital rhabdomyosarcoma.
