BACKGROUND: Pseudomeningoceles mostly happen attributable to prior trauma or surgical procedure and are sometimes situated within the posterior paraspinous tissues. Right here, we report a case of an intraosseous pseudomeningocele that mimicked an intra-osseous T2 hyperintense lesion within the L1 vertebral physique.
CASE DESCRIPTION: A 64-year-old male introduced with again, left lateral thigh and left knee ache lasting a number of months. He had no prior historical past of trauma or surgical procedure. Radiographs of the lumbar backbone confirmed delicate levoscoliotic curvature of the lumbar backbone, Baastrup’s adjustments between the spinous processes, multilevel degenerative disc illness and side arthropathy. Magnetic resonance imaging (MRI) of the lumbar backbone carried out with out intravenous distinction confirmed extreme spinal canal stenosis from L1-L2 to L3-L4 and reasonable spinal canal stenosis at L4-L5. MRI additionally confirmed a 2.5-cm T2 hyperintense lesion involving the posterior facet of the L1 vertebral physique, with questionable contiguity with cerebrospinal fluid. Computed tomography (CT) myelogram was carried out as an alternative of biopsy. CT myelogram confirmed contiguity of the lesion with the intrathecal distinction and a hire within the posterior longitudinal ligament and anterior dura according to an intraosseous pseudomeningocele. The affected person opted for non-operative administration of the pseudomeningocele and his lumbar stenosis attributable to medical comorbidities.
CONCLUSIONS: This case illustrates a uncommon case of an intra-osseous pseudomeningocele and highlights the significance of CT myelogram for analysis.
