Isolated loss of inferior pubic ramus: a case report.

INTRODUCTION

It has been stated that regulation of the development of the iliac bone is different from that of the ischium and pubis. There are well-known clinical syndromes concerned with hypoplasia of ischiopubic bone, such as small patella syndrome, nail-patella syndrome, ischiopubic-patellar hypoplasia, and ischiopubic hypoplasia.

CASE PRESENTATION: A fit and otherwise healthy 35-year-old woman presented with pain in the left lower limb of 6 months duration. She sought advice from an orthopedic surgeon and was referred for exclusion of a primary soft tissue neoplasm. There was no history of trauma, chronic medical illness or surgical operations. Full systemic examination, laboratory investigations and whole body imaging showed no soft tissue swelling or any other bony defects. Isolated loss of the left inferior pubic ramus and thinning of the superior pubic ramus were detected, raising the question of whether the lesion was a secondary osteolytic lesion, a primary osteolytic lesion or due to endocrine disease.

CONCLUSION

Isolated loss of the inferior pubic ramus with no concomitant bony or soft tissue anomalies is previously unreported. To the best of the author's knowledge, this finding has not been described previously.
