ABSTRACT
Traumatic spondylolisthesis of the lumbosacral junction (SPL) is a spinal injury rarely seen in current practice. Few cases are reported in the literature. It arises from complex trauma of high-energy mechanisms. We discussed the case of a young patient. He is 24 years old without notable pathological history victim of a traffic road accident. Clinically, he has no sensory or motor deficit, it is a spinal trauma classified American spinal injury association E (ASIA E) with severe back pain. A whole-body CT scan performed on admission showed a grade 2 L5-S1 SPL. A lumbar MRI revealed a tear of the disc at L5-S1. We performed a laminectomy to decompress the dural sheath and cauda equina roots with transforaminal lumbar interbody fusion. A postoperative CT scan showed the reduction of the spondylolisthesis. Two months later, the patient resumed walking. Surgery is the gold standard for the management of traumatic SPL. The aim of surgery is to achieve neural structure decompression and obtain stability with fusion.
ABSTRACT
Spinal epidermoid cysts are rare benign tumors. The etiology can be acquired or congenital. We present a rare case of an 18-month-old girl presented 4 months ago with spontaneous intergluteal swelling fistulized to the skin and lower limbs weakness. Magnetic resonance imaging of the spine demonstrated an intradural tumor from L3 to L5 levels, isointense on T1, hyperintense on T2-weighted images with contrast enhancement after gadolinium injection without any coexistent spinal dysraphism suggested the diagnosis of the dermal sinus. The patient underwent triple-level laminectomy for biopsy and tumor resection. A pearly white tumor was encountered, with a subsequent biopsy confirming it to be an epidermoid tumor. At 6-month follow-up, the neurologic deficit was improved. Spinal epidermoid cysts are rare tumors that evolve slowly. Complete total removal is the treatment of choice.
