1310J Neurosurg / Volume 120 / June 2014 tion, she was referred to an outside neurologist who found ophthalmoplegia of the left eye and sensory deficit in the left V1 distribution.Clinical Course. The patient was then referred to the emergency department of the NewYork-Presbyterian Hospital where her examination was notable for 2 mm of ptosis in the left eye, impaired adduction, elevation, and depression of the left eye consistent with a partial left oculomotor nerve palsy and an inability to abduct the left eye, consistent with a complete left abducens palsy. Magnetic resonance imaging showed an expansile mass in the left CS (Fig. 1A) presumed to be a schwanomma.Several weeks later, the patient's left periorbital pain and numbness as well as the vertical motility of the left eye improved. However, repeat MRI showed a slight increase in lesion size and multiple serpentine T2 hyperintense structures, which together were suggestive of a CSCH (Fig. 1B). A cesarean section was recommended to reduce the risk of enlargement and hemorrhage during delivery. The neurosurgery team recommended no acute surgical treatment given the extent of the lesion within the CS, close follow-up, and postpartum imaging to assess for possible spontaneous involution.At 30 weeks of gestation the patient presented with progressive left orbital pressure, lid edema, worsened ptosis to 5 mm of the left eye and a new 2-mm anisocoria with mydriasis of the left eye. Repeat MRI revealed a significant enlargement of the lesion with extension to the orbital apex (Fig. 1C). There was severe compression of the left internal carotid artery and increased impingement of the left optic nerve. The patient was offered the option of immediate delivery, but she declined. A cesarean section was scheduled for 37 weeks.At 35 weeks of gestation, the patient was referred to a neuro-ophthalmologist for declining left visual acuity. Neuro-ophthalmic examination confirmed a complete left abducens palsy and partial left oculomotor palsy, including a mild adduction defect, mild ptosis and mydriasis, worse in light. However, there was no relative afferent pupillary defect. Visual acuity in the left eye improved with a +2 lens, consistent with blurry vision from a lens accommodation paresis associated with the oculomotor palsy rather than from optic nerve compression (Fig. 2).Postpartum Course. The patient underwent the scheduled cesarean section without complication. Two weeks postpartum, she developed complete ptosis and decreased supra-and infra-adduction of the left eye, consistent with worsened oculomotor nerve function. Furthermore, in addition to left mydriasis in the light, a relative miosis in dim light had developed, consistent with ...
