Surgical Excision of Orbital Cysticercosis Lodged in Superior Oblique Muscle: Clinical Case Report.

Ding J, Zhao H, Lin J - Medicine (Baltimore) (2015)

Bottom Line: Ocular motility examination revealed a restriction of the right eye in levoelevation.A contrast-enhanced computed tomographic scan of the orbit revealed the presence of a well-defined hypodense cystic lesion within the right superior oblique muscle.The patient was diagnosed with orbital space-occupying mass with acquired Brown syndrome.Surgical exploration of the superior oblique muscle was performed, and the cyst was removed from the eye and confirmed by histopathological examination.

ABSTRACT
Ocular cysticercosis refers to parasitic infections in humans. Most cases were treated by medicine. The case we reviewed was rarely reported with successful surgical intervention treatment.This case report describes a patient with cysticercosis existing in superior oblique tendon. The main symptom of the patient was recurring history of painless orbital swelling and double vision in upgaze. Ocular motility examination revealed a restriction of the right eye in levoelevation. A contrast-enhanced computed tomographic scan of the orbit revealed the presence of a well-defined hypodense cystic lesion within the right superior oblique muscle.The patient was diagnosed with orbital space-occupying mass with acquired Brown syndrome. Surgical exploration of the superior oblique muscle was performed, and the cyst was removed from the eye and confirmed by histopathological examination. After surgery, an ocular motility examination revealed orthotropia in the primary position and downgaze, with mild restriction in levoelevation.Surgical removal could substitute for medical therapy when the cysticercosis is lodged in the superior oblique muscle, although, prior to surgery, important factors, such as patient requirements, surgical skills of the surgeon, and cyst placement, should be considered.

Figure 6: Clinical photograph of 9 diagnostic positions after operation and the measurements of deviation (showing limitation of elevation in adduction of the right eye). ET = esotropia, LHT = left hypertropia, Ortho = orthotropia, XT = exotropia.

Mentions: The patient still complained of diplopia in the upgaze during his 9th-month follow-up. Ocular motility examination revealed orthotropia in the primary position and downgaze; a mild restriction in the superior adduction and abduction was also observed (Figure 6). Proptosis returned to normal, and hertel exophthalmometer readings were at 19 mm for both eyes. The eyelid abnormalities dissipated over time. Lateral canthus scarring showed improvement during the 9th-month follow-up.
