No pathology seen on the chest or abdominopelvic films.
Intrauterine device projected onto the sacrum.
Incidentally noted 11 pairs of ribs and lumbosacral transitional vertebra - sacralization of L5.
Case Discussion
Since 11 rib pairs can be counted on the upright frontal chest film, one can confidently determine that the lumbosacral transitional vertebra is, in fact, a sacralized L5 vertebra.
