Case in brief
A 15-year-old presented with progressive left eye bulging and intermittent periorbital pain. Imaging showed a well-defined, homogeneous, enhancing mass in the left lacrimal gland, with decreased diffusivity, smooth bone remodeling, and anteromedial displacement of the globe; no other systemic findings were reported. The lesion was completely excised, and histopathology showed hyaline vascular-type Castleman disease.
What made this case unusual
The report describes an isolated lacrimal gland lesion in a pediatric patient, an exceptionally uncommon orbital presentation of Castleman disease.
Diagnostic / clinical pearl
Castleman disease can present as a well-circumscribed, homogeneous lacrimal gland mass with decreased diffusivity and smooth bone remodeling; include it among the differential diagnoses for this imaging pattern.
