Description
Hiroki Narita and six co-authors untangle a rare artery variant behind a man's returning face pain, in a 2026 case report. Trigeminal neuralgia strikes with electric jolts, and blood vessels pressing the nerve are the usual cause.
Nineteen years after his first decompression surgery, the 79-year-old's pain returned. Imaging found a fetal artery remnant, a persistent primitive trigeminal artery, giving off the very cerebellar artery that squeezed the nerve. An old Teflon pad had also grown into a granuloma hiding the vessel. Three-dimensional reconstructions mapped the tangle before surgery. The team cleared the granuloma and moved the artery aside. Rare vessel families, they warn, draw unusual compression maps.
