Hematocolpos. An unusual cause of sciatica in an adolescent girl.

Study Design: A case report.

Objective: To document the occurrence of hematocolpos causing sciatica and leg weakness in an adolescent girl.

Summary Of Background Data: Low back pain resulting from hematocolpos has been reported previously but not associated with symptoms of sciatica or neurologic weakness.

Methods: The authors were involved in the care of this patient, and all medical records, radiologic investigations, and related literature were reviewed.

Results: After being checked for longstanding symptoms of sciatica and leg weakness, the patient underwent a computed tomographic examination of lumbar spine, which showed a large collection in the pelvis consistent with hematocolpos. Surgical drainage of the collection was associated with complete resolution of her symptoms.

Conclusions: Awareness of hematocolpos as a possible cause for sciatica and neurologic symptoms in the lower limbs may lead to earlier diagnosis and, therefore, reduced morbidity in the investigation of the adolescent girl.
