Table 2 Imaging features, management and outcome of patients

From: Imaging diagnosis and management of primary spinal hydatid disease: a case series

S. no. MRI findings Imaging differentials Imaging evaluative for primary hydatid disease elsewhere Management Outcome Recurrence
Location Signal characteristics Compression over cord/ cauda equina Extraspinal soft tissue involvement
1 Extradural cystic lesion at D8-9 level T1-hypo, T2/STIR-hyper with thin smooth hypo-wall, No enhancement Cord compression present Absent Hydatidosis Cysticercosis Cystic tumor Negative D8 to D10 laminectomy with cyst excision f/b albendazole therapy Improved Absent
2 D9-10 vertebral body multiloculated cystic lesion T1-hypo, T2/STIR-hyper with thin smooth hypo-wall, patchy rim enhancement Cord compression present Present Hydatid disease Negative D8-D10 transpedicular rod and screw fixation with D9 hemilaminectomy and cyst excision Improved Absent
3 L5 vertebral body multiloculated cystic lesion T1-hypo, T2/STIR-hyper with thin smooth hypo-wall, patchy rim enhancement Cauda equina compression present Present Hydatid disease Negative L3-4 7 S1 transpedicular rod and screw fixation with L4-5 laminectomy and L5 corpectomy with total cyst excision Motor weakness persisted Absent
