Extensive paraspinal tuberculosis masquerading malignant tumor in an elderly male

Paraspinal tuberculosis is an uncommon manifestation of extrapulmonary tuberculosis, and in rare cases, these lesions can mimic malignant lesions. We report a case of an elderly man where imaging showed extensive left paraspinal lesion which was mimicking malignant neoplasm. The patient underwent L3–L4 unilateral partial laminotomy, there was grayish, relatively avascular lesion in the left paraspinal region, involving the left psoas muscle and going into the neural foramina, and a subtotal resection of the lesion could be performed. However, after biopsy, it turned out to be tuberculoma, and the patient was on antitubercular therapy and doing well. The present case illustrates that extensive involvement of the paraspinal soft tissue and adjacent bony structures on imaging in tuberculosis can mimic malignant tumors. Conservative surgical excision will help in preserving the bony elements and in establishing the diagnosis.
