A 47-year-old woman presented with six episodes of horizontal binocular double vision over a 2-year period. CT imaging was significant for extensive dural calcification in the spine and calcification of the skull base, likely involving Dorello's canal. Biochemical testing revealed a persistently low alkaline phosphatase level. Recurrent nerve palsy may possibly be induced by mechanical compression of the sixth cranial nerve in Dorello's canal from calcification due to hypophosphatasia syndrome.
一名47岁女性在2年时间里出现了6次水平性双眼复视发作。CT成像显示脊柱有广泛的硬脑膜钙化以及颅底钙化,可能累及Dorello管。生化检测显示碱性磷酸酶水平持续偏低。复发性神经麻痹可能是由于低磷酸酯酶症综合征导致钙化,进而机械性压迫Dorello管内的第六颅神经所致。
