Abstract
All orbital tissues, including extra‑ocular muscles, can be affected by the varicella‑zoster virus (VZV). However, only a minority of all individuals with herpes zoster infections present with herpes zoster ophthalmicus. The present study reports the case of a middle‑aged male patient presenting with an acute intractable right‑sided headache. His neurological examination yielded normal results. The analysis of cerebrospinal fluid by biochemistry and cultural analysis yielded normal results; however, the analysis of this fluid using polymerase chain reaction yielded a positive result for VZV. Thus, treatment with acyclovir was commenced. Brain magnetic resonance imaging revealed a bilateral intraorbital intraconal enhancement consistent with myositis. His symptoms evolved into a shock‑like pain over the scalp associated with painful ocular movements. On the 2nd day of admission, he developed new vesicular lesions found on the right‑side cranial nerve V1 dermatome. By the 6th day of admission, he was asymptomatic, and his physical examination revealed the resolution of the dermatologic manifestations of the VZV. The patient was stable for outpatient follow‑up with ophthalmology and was discharged on an oral valacyclovir course for 7 days. To the authors' knowledge, there are four cases reported in the literature of herpes zoster ophthalmicus with orbital myositis prior to the appearance of vesicular lesions. Thus, it is suggested that VZV serology be investigated before a final diagnosis of idiopathic orbital myositis is made.
