Table 2 Imaging features, management and outcome of patients

S. no.	MRI findings				Imaging differentials	Imaging evaluative for primary hydatid disease elsewhere	Management	Outcome	Recurrence
S. no.	Location	Signal characteristics	Compression over cord/ cauda equina	Extraspinal soft tissue involvement	Imaging differentials	Imaging evaluative for primary hydatid disease elsewhere	Management	Outcome	Recurrence
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
