[Paresis of the femoral nerve in pelvic extraperitoneal hematoma--case reports and literature review].

The authors describe two rare cases of femoral nerve paresis in pelvic extraperitoneal hematoma in children. The first case was a 13-year-old girl, with no trauma in her medical history, in whom the paresis was suspected to have inflammatory or tumorous etiology; the other case was a 14-year-old boy injured during playing football. In both patients, extraperitoneal pathology of the pelvis was evident clinically and was shown in CT scans; paresis of the femoral nerve was demonstrated by EMG. In both cases, surgical intervention revealed a hematoma causing neuropathy. This was removed and, within a year of first sign appearance, both patients were free from neurological symptoms. The authors consider early surgery to be a decisive factor in the course of this neurological complication, as the regeneration of nerve structures took nearly a year despite the adolescent age of the patients. No reports of similar conditions in children treated at the same institution were found in the relevant international literature.
