ABSTRACT
Objective: Traumatic superior orbital fissure syndrome is a rare complication that occurs in association with craniofacial trauma. In the present case, there were no associated orbital fractures or other lesions to explain. Methods: We present a-16-year-old patient with total ophthalmoplegia, ptosis, and anesthesia of the upper eyelid and forehead 6 hours after a reported trauma to the left eye. We measured the width of the superior orbital fissure on the horizontal plane including the optic canal using computed tomography scans. Results: Radiological examinations did not reveal any orbital fractures. However, the superior orbital fissure on the affected side was only 1.86 mm, increasing susceptibility to indirect trauma. Conclusions: A narrow superior orbital fissure may play a role for superior orbital fissure syndrome altering the transmitted force from the trauma and edema.
ABSTRACT
A 12-year-old girl was referred to our clinic because of unilateral conjunctivitis not responding to treatment. In the left eye, lower bulbar and tarsal conjunctiva had a polypoidal appearance due to micronodules and there was a subconjunctival nodular mass in the inferior fornix. Systemic examination was unremarkable except for a left preauricular lymphadenopathy. Excision biopsy of the subconjunctival mass revealed a granulomatous inflammation with caseation necrosis, but acid-fast bacilli (AFB) was negative. Fine needle-aspiration biopsy of the preauricular lymph node was performed. In microbiological examination, both AFB and mycobacterial culture were positive. The isolated mycobacteria strains were identified as Mycobacterium tuberculosis complex and full remission was achieved with 6 months of anti-tuberculosis treatment. Although primary tuberculous conjunctivitis is a very rare condition, it should be considered in the differential diagnosis of treatment-resistant unilateral conjunctivitis. For definitive diagnosis, microbiological and histopathological examinations should be performed both in conjunctiva and regional lymph node.
ABSTRACT
Sphenoid sinus carcinomas occur rarely compared with other sinonasal tumors. A case of sphenoid sinus squamous cell carcinoma presenting with acute, isolated optic neuropathy and visual loss is presented herein along with the related literature. A 37-year-old man with sudden decrease in visual acuity in his left eye of 15 days' duration was referred. He had received high-dose intravenous corticosteroid therapy with the provisional diagnosis of retrobulbar neuritis, and his visual acuity had temporarily improved at this time. Magnetic resonance study showed a space-occupying lesion in the left posterior ethmoid and sphenoid sinuses, adjacent to the intracanalicular optic nerve, and an increase in optic nerve signal intensity. An excisional biopsy of the sphenoid lesion revealed squamous cell carcinoma. After stereotactic radiotherapy and chemotherapy following surgery, a total loss of vision and optic atrophy developed in the left eye. No other complication, tumor recurrence, or metastasis occurred during 30 months of follow-up.
