[Osteitis condensans ilii].

OBJECTIVE

The description of a case of osteitis condensans ilii.

DESIGN

Descriptive.

SETTING

Base health area.

PATIENTS AND OTHER PARTICIPANTS

A 24-year-old puerperal woman.

INTERVENTIONS

Analgesic treatment.

MEASUREMENTS AND MAIN RESULTS

We were presented with the history of a woman with low lumbar pain of a mechanical character, after a dystocial birth two months previously. The radiology showed a triangular bony condensation on the edge of the sacroiliac joints.

CONCLUSIONS

Osteitis condensans ilii is a benign structure, almost only ever found in women who have borne children. Its presentation is asymptomatic or nonspecific (low lumbalgia). Its very specific radiological image needs to be distinguished carefully in order to avoid diagnostical confusion with ankylosing spondylitis and other causes of sacroiliitis.
