Spontaneous resolution of postoperative lumbar pseudomeningoceles: A report of four cases
A 17-year-old boy underwent posterior instrumentation from L2-S1 vertebra and anteriorcolumn reconstruction for an unstable burst fracture of L4 vertebra. Intraoperatively, the left L4 nerve root was avulsed with a dural defect. A fat graft was used to seal the CSF leak at the time of wound closure. The patient had complete motor and sensory loss in left L4 root distribution which remained unchanged postoperatively. Postoperatively, the patient was put on routine antibiotics for gram positive and negative coverage and analgesics. He was catheterized and advised strict bed rest. On the 5th postoperative day, when the patient was mobilized, a fluctuant swelling of approximately 12 × 8 cm was noticed at the operated site. Since the patient remained asymptomatic and the wound healed uneventfully, he was discharged after suture removal and was observed closely. At 3 months followup, the swelling had resolved completely both clinically and radiologically [].
