Figure 1. Clinical findings of the cat during the clinical course. (A)
At initial presentation, blepharospasm in the right eye was observed.
(B) On day 19, corneal ulceration at dorsal site did not improve, and
restriction of the eyelids was prominent. (C, D) On day 75, exposure
keratitis in the right eye deteriorated due to persisting eyelid
restriction, and resistance to posterior ocular compression was
observed.
Figure 2. Imaging findings. (A) On day 75, Ultrasound examination
detected no obvious mass in both the globe nor in the orbit. (B) On day
138, A computed tomography scan revealed a high intensity
space-occupying lesion in the orbit of right eye (*).
Figure 3. Histopathological findings of the tumor. (A) Hematoxylin-eosin
staining showed proliferation of bland spindle cells with moderate
collagen matrix. (B) Immunohistochemical staining showed moderate
cytoplasmic labeling of smooth muscle actin in spindle tumor cells.
