Abstract:
A 6-year-old castrated male mixed breed dog presented to the "Louisiana State University Veterinary Teaching Hospital &-anonymized for review" ophthalmology service with marked exophthalmos and lagophthalmos of the left eye and soft tissue swelling medial to the zygomatic arch. A computed tomography (CT) scan was performed, and it revealed a well-marginated, lobulated, homogenously fat density involving the retrobulbar space. Preliminary results of a fine-needle aspirate (FNA) and biopsy were not conclusive, and a modified transfrontal orbitotomy was performed to remove the mass. Histopathological evaluation was diagnostic for retrobulbar infiltrative lipoma. Nine months after the surgery, the eye appears within normal limits with no evidence of recurrence.
