An isolated subcutaneous paraspinal pseudo-tumor—more to it than meets the eye—a case report and review of literature.

A 4-year-old male child presented to us with a paraspinal pseudo-tumor over the mid-back region with pain being his only symptom. On initial ultrasonography, it was presumed to be a nerve sheath tumor, but on an excision biopsy and histopathology, it proved to be a subcutaneous cysticercosis. Furthermore, an MRI of the brain showed a ring enhancing lesion with vasogenic edema, which confirmed the diagnosis of a neurologically symptomless neurocysticercosis. We treated the patient with albendazole and a short course of dexamethasone. There was complete resolution of the painful subcutaneous swelling, and the patient remained neurologically symptomless at all subsequent follow-ups. Resolution of the brain lesions was seen in the 6-month MRI follow-up. Although rare, orthopedic surgeons should consider the possibility of parasitic infections when dealing with small near-asymptomatic soft tissue paraspinal swellings of uncertain etiology. A thorough investigation in such cases can be lifesaving. [ABSTRACT FROM AUTHOR]
