Summary
This case report details a rare instance of cerebral gumma, a syphilis manifestation in the brain. Prompt diagnosis and penicillin treatment led to tumor size reduction, highlighting the importance of considering syphilis in neurological cases.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Cerebral gumma, a rare manifestation of tertiary syphilis, presents diagnostic challenges.
- Distinguishing gumma from intracranial tumors like lymphoma on imaging is crucial.
Observation:
- A 74-year-old male presented with gait disturbance and memory loss, exhibiting neurological deficits including right homonymous hemianopsia and hemiparesis.
- Positive serological tests for syphilis (blood and CSF) and CSF analysis showing pleocytosis and elevated protein were noted.
- CT scan revealed an irregular low-density area with abnormal contrast enhancement, initially suggestive of malignant lymphoma.
Findings:
- Histopathological examination confirmed cerebral gumma, despite initial radiological suspicion of lymphoma.
- Treatment with penicillin resulted in a significant reduction in lesion size, as evidenced by follow-up CT scans.
- Neuroradiological characteristics of cerebral gumma are infrequently described, complicating diagnosis.
Implications:
- This case underscores the importance of considering neurosyphilis, specifically cerebral gumma, in the differential diagnosis of intracranial lesions, even when imaging mimics malignancy.
- Accurate diagnosis relies on integrating clinical presentation, serological markers, and response to antisyphilitic therapy.
- Early recognition and treatment of cerebral gumma can prevent further neurological damage.
