We describe a series of 3 cases of the rare intramedullary form of primary spinal neurocysticercosis. The cases were seen in varied age groups and showed different profiles at presentation. All the cases were thoroughly evaluated clinically and radiologically. Serologic tests were not conducted. In all cases, magnetic resonance imaging showed a large intramedullary lesion in the thoracic spinal cord consisting of a cystic lesion with a well-defined intramural nodule. One case was managed with steroids and cysticidal therapy, a second case was managed with steroids and surgery (2 emergency procedures), while the third case was managed without any medical or surgical intervention, as the patient was unwilling for either. All cases showed good neurologic recovery. In the second case where surgery was done, histologic examination of the resected specimen demonstrated the cysticercal parasite surrounded by mixed inflammatory infiltrate. As there were no intracranial lesions in all 3 cases, the final diagnosis was primary isolated intramedullary neurocysticercosis. Primary isolated intramedullary-neurocysticercosis remains a rare condition afflicting the spinal cord. It forms a small subset of cysticercal infestation of the neuraxis. Such evidence is rare, and only anecdotal reports are available. Our case series captures the wide spectrum of presentations, as well as the management options, and highlights the varied ways in which these cases were managed.
