Background. Spinal neurosyphilis manifesting as a solitary syphilitic gumma is exceedingly rare. There are non-specific imaging findings and challenges in the diagnosis of spinal syphilitic gumma, which could be easily misdiagnosed as tumor lesions and require surgical resection or biopsy. Clinical Presenta- tion. We report the case of a 45-year-old female patient who was diagnosed with Spinal syphilitic gumma. Our case is the first reported case of spinal cord syphilitic gumma with intradural-extramedullary and intra- medullary involvement. Conclusion. Spinal syphilitic gumma exhibits diverse clinical manifestations, lacks specific imaging features, accompanied by the patient's history deliberately concealed. Since clinicians do not have sufficient knowledge about such rare cases, misdiagnosis and missed diagnosis will be likely. When there is clinical suspicion for spinal syphilitic gumma, clinicians should pay close attention to relevant medical history, carry out a comprehensive physical examination and specific serological tests and cerebro- spinal fluid (CSF) analysis. In summary, in cases with stable neurologic conditions, a trial administration of intravenous penicillin with follow-up imaging may be the optimal treatment option, and in cases with rapid progression or acute exacerbation, a surgical resection together with systemic antibiotic treatment for syphilis after surgery may be the best treatment strategy. Key words: neurosyphilis, Spinal cord gumma, spinal cord.

The lesion was found to be a solid mass at the level of T8-T9 combined intradural-extramedullary (about 3×1.5×0.5cm in size) and intramedullary (about 1.8×1.3×0.6cm in size) involvement. The lesion didn’t have a clear borderline and coating, with medium hard- ness, had medium hardness and not so rich blood sup- ply. It lay at the lateral side of spinal canal. The lesion was located in the spinal canal laterally, bound at the nerve root with severe adhesions. Lesion debulking was performed. A diagnosis of the lesion could not be made on the intraoperative frozen section, which showed spindle cells. 5 days later, pathologic examination of paraffin section revealed granulomatous inflammation with small areas of caseous necrosis, and multinucleat- ed giant cells infiltration, surrounded by large numbers of lymphocytes and small numbers of neutrophils.

And the treatment for syphilis was administered with intrave- nous penicillin G (19.6 million U/day, and 4.9 million U QID) for 14 days, then intramuscular benzathine penicillin G (2.4 million U QW) for 21 days. After the treatment, the patient’s right lower limb weakness and left lower limb numbness were improved. Figure 2.
