AI Article Synopsis
- A 12-year-old spayed Beagle presented with exophthalmos, leading to a CT scan that showed a distinct mass behind the left eye.
- The mass had varied tissue density and slightly increased enhancement after a contrast agent was used.
- After surgical removal, the mass was confirmed to be a hibernoma, a benign tumor made of brown fat, which can often be misidentified in imaging studies.
Article Abstract
A 12-year-old female spayed Beagle was referred for investigation of exophthalmos. CT revealed a well-defined, retrobulbar mass causing rostro-dorsal displacement of the left globe. The mass had a mildly heterogeneous precontrast soft tissue attenuation with mild heterogeneous enhancement following iohexol administration. The mass was surgically removed en bloc with an orbital exenteration. Histopathology confirmed the mass to be a hibernoma, a benign tumor of brown adipose tissue. Hibernomas have CT characteristics consistent with both benign and malignant adipose tumors and may be underrecognized by radiologists.
