title: Iliolumbar ligament ossification in undifferentiated seronegative spondyloarthropathy.
abstract: The case of a man suffering from undifferentiated seronegative spondyloarthropathy (uSpA) without spine involvement and with iliolumbar ligament ossification is reported. Unlike a similar previously published case showing ossification only of the middle part of the left ligament, our patient had ossification of the whole course of both ligaments.
