Purpose: To report a case of (neuro)sarcoidosis presenting solely with recurrent cranial nerve palsies in a 57-year-old Caucasian female.
Methods: Case report with clinical imaging.
Results: A 57-year-old female first presented with a right sixth nerve palsy, which resolved spontaneously after 6 months. Three years later she was diagnosed with a sixth nerve palsy in the fellow eye followed by a complete palsy of the left third cranial nerve four months after. Medical history consisted of migraine and hypercholesterolemia. Further neurological and ophthalmic work-up was unrevealing at first. After repeated magnetic resonance imaging, an enhancing lesion in the left cavernous sinus was seen, which was initially diagnosed as a meningioma. However, imaging of the chest revealed an image of sarcoidosis, and the lesion and ophthalmoplegia of the left eye disappeared with systemic corticosteroid treatment.
Discussion: Sarcoidosis is the ultimate imitator and the possibility of neurosarcoidosis must be taken into account when presented with unexplained ophthalmoplegia. Neurosarcoidosis has imaging properties very similar to other diseases such as a meningioma, and misdiagnosis occurs easily. Spontaneous recovery of ophthalmoplegia can rarely occur in neurosarcoidosis.
