Purpose: To report a case of bilateral trochlear nerve palsy following cisternography.
Case summary: A 43-year-old male with intermittent watery rhinorrhea persisting for 3 months visited the neurosurgery department of our institute. His past medical history included removal of a pituitary adenoma 22 years prior to presentation. Cerebrospinal fluid leakage was suspected and cisternography was performed. The patient was referred to our ophthalmology department for diplopia 3 days after the cisternography. An alternate prism cover test showed 5 prism diopter (PD) right hypertrophia in the primary position, and underaction of bilateral superior oblique muscles and overaction of the left inferior oblique muscle. A positive Bielschowsky test with the head tilted to either side was observed and excyclotorsion was 9¡Æ on the double Maddox rod test. The patient was diagnosed with bilateral trochlear nerve palsy. After 2 years of follow- up, diplopia persisted and recession of the bilateral inferior oblique muscles was performed. After the surgery, diplopia disappeared, the fundus photography showed no excyclotorsion, and the double Maddox rod test indicated 3¡Æ of excyclotorsion.
Conclusions: Cisternography should be carefully performed due to the possibility of bilateral trochlear nerve palsy, an extremely rare but possible occurrence following the procedure.
