Those patients are usually diagnosed with neurosyphilis. It is generally recommended that anyone with neurosyphilis also be tested for HIV. Treating neurosyphilis requires patients to take all of their medication, and take it reliably. Therefore, in order to make certain people are getting their medication, treatment often takes place in the hospital. This involves receiving an IV of aqueous crystalline penicillin G every four hours, or continuously, for 10 to 14 days. For people who will definitely be compliant with medication, it is possible to combine penicillin injections with oral Probenecid a uric acid reducer for 10 to 14 days.
Longer treatment may be necessary. Fortunately, in the early stages of neurosyphilis, treatment is very effective. It can reverse many of the physical and psychiatric side effects of the disease. However, for people with later stage neurosyphilis, treatment may not be as effective at restoring function.
Damage to the brain, of the sort associated with dementia, is not always reversible even if the infection is cured. Neurosyphilis can be a scary diagnosis.
It is also a largely preventable one. Reliably practicing safer sex, including oral sex , can vastly reduce a person's risk of acquiring a syphilis infection. In addition, neurosyphilis is much more common in later stages of syphilis than in early stages. Therefore, regular screening and prompt treatment can also have a big impact on reducing risk.
If you're someone who is at risk for syphilis, you can always ask to be screened at your annual doctor's visit. If they're drawing blood already, you may not even notice when they run the test.

Axial T1 WI post-Gd administration B demonstrated contrast enhancement along the orbital segment of the left optic nerve arrowheads. In another patient with neurosyphilis, comparative images showed papilloedema on left arrowheads in T2 WI C.
Coronal T1 WI post-Gd administration revealed a peripheral optic nerve contrast enhancement D compatible with left perineuritis and papilitis arrowhead. In an additional patient with cat scratch disease, comparative images showed a small bulging of the left optic disc arrowhead on T2 WI E. Axial T1 WI post-Gd administration confirmed short-segment enhancement of the left optic nerve localized to the optic nerve-globe junction arrowhead.
The most recognized clinical red flags that should be considered are as follows: evidence of retinopathy, uveitis, severe continuous orbital pain, persistent complete loss of vision even after a month and macular star on the ophthalmological examination. Additionally, bilateral simultaneous ON, painless and severe disc swelling and retinal hemorrhages are very uncommon features in an MS demyelinating ON 3 3.
Although ON is a clinical diagnosis, imaging, especially MRI, plays an important role in confirming the infection and contributing information to determine its prognosis. ON results in edema and it is often associated with long segment of Gd enhancement, which reflects the breakdown of the blood-brain barrier. Non-arteritic anterior ischemic optic neuropathy and neuromyelitis optica NMO are often described as the classical differential diagnoses for MS ON; however, it is important to recognize several infectious diseases that may be important mimickers of demyelinating processes.
Optic nerve involvement by T. Optic nerve involvement may be unilateral or bilateral and becomes apparent as perineuritis, anterior or retrobulbar ON or papilloedema. In the case of ON, the involvement of other cranial nerves, such as motor ocular nerves 23 Bilateral ocular perineuritis as the presenting feature of acute syphilis infection.
J Neurol ; Cat scratch disease is an infrequent cause of optic neuropathy that is associated with the classic macular star formation on ophthalmological examinations. Orbital MRI shows several characteristic features that should support specific suspicions.
Cat scratch disease is characterized by a unilateral short-segment enhancement of the optic nerve localized to the optic nerve-globe junction with less edema in the region of Gd enhancement or in locations other than those that are usually observed in the demyelinating processes 24 Optic neuropathy secondary to cat scratch disease: distinguishing MR imaging features from other types of optic neuropathies.
Additionally, bulging of the affected optic disc and extra-axial dural based masses may be observed, increasing the specificity of the imaging findings Figure 9.
Figure 9. Axial comparative images on FLAIR A-B showed symmetric involvement of the cerebral peduncle and ventral part of the pons along the corticospinal tracts arrowheads. Note the predominant asymmetric involvement of the cerebellar peduncles. Note the restricted diffusion of water molecules in these lesions C. Toxocariasis is an important differential diagnosis, particularly in children with ON suspicion. In ocular larvae migrans , in which pathologic effects on the host are restricted to the eye and the optic nerve, the optic nerve involvement most commonly occurs in its head due to the direct intraocular involvement 25 Optic neuritis in cerebral toxocariasis.
J Neurol Neurosurg Psychiatry ; In children, the disorder usually occurs as a chronic granulomatous endophthalmitis, which is identified as a vitreous central mass with variable signals on T1 and T2 and moderate Gd enhancement, which might be associated with subretinal exudate and retinal detachment. Toxocariasis may be associated with other neurological symptoms, such as eosinophilic meningoencephalomyelitis, encephalitis, extramedullary space-occupying lesion, brain vasculitis, seizures, and most likely behavioral disorder.
Vision loss due to optic nerve damage may occasionally be a dominant symptom. Optochiasmatic arachnoiditis, which is the third ventricular compression of optic chiasma due to hydrocephalus and optic nerve granuloma, is a likely factor for determining clinical manifestations. MRI may reveal choroid tubercles, which are more frequent in tuberculous meningitis associated with miliary tuberculosis and are virtually pathognomonic of tuberculous etiology 26 Garg RK.
Tuberculosis of the central nervous system. Postgrad Med J ; Ethambutol is used to treat tuberculosis; however, it is also associated with permanent visual loss.
As ON has been described as one of the toxic effects of ethambutol, it emerges that the drug appears to have a dose-related side effect 27 Ethambutol-induced optic neuropathy: a nationwide population-based study from Taiwan. The Brit J Ophthalm ; There are other reports concerning rare causes of ON, such as neuroborreliosis, West Nile virus, Epstein-Barr virus, mycoplasma and herpes virus. The clinical aspects associated with a more extensive ocular impairment and a non-MS radiological picture may suggest a non-MS ON.
The most well-known clinical red flags include the following: complete transverse myelitis, radiculopathy and areflexia. In contrast to the brain, typical focal, ovoid, spinal cord MS lesions no longer than three vertebral segments in length, usually partially extending into the axial plane, commonly in a dorsolateral location with variable Gd enhancement, with minimal local edema, and without mass effect are rarely found in the spinal cord in other conditions, such as infectious diseases.
MS lesions are more common in the cervical segment and are rarely found in the conus medullaris. The identification of T1 hypointense lesions black holes is extremely rare.
However, in children, the MS inaugural event may mimic ADEM, which usually shows a more diffuse spinal cord impairment with lesions longer than three vertebral segments in length that frequently occupy more than two-thirds of the cross-sectional area of the cord 28 Acute disseminated encephalomyelitis. In such cases, differentiation from infectious diseases, particularly viral infections, is crucial.
Family herpes virus is a viral agent that is most frequently associated with myelitis. The clinicoradiological presentation is similar, and the etiological diagnosis can be confirmed only by laboratory tests. HHV types 1, 2, 6 and 7 share an overlapping imaging presentation, characterized by long-segment hypersignal on T2 with variable Gd enhancement.
There are reports of hemorrhagic lesions, particularly in type 1 HHV 29 Neuroimaging in acute transverse myelitis. Neuroim Clin N Am ; Myelitis is a rare manifestation of VZV infection and generally occurs after reactivation of a latent infection. As in the brainstem, changes are associated with the nerve's apparent origin in the nervous system and are most severe at the dorsal root entry zone and posterior horn of the involved dermatome.
Additionally, the MRI may show a variable imaging presentation, including single or multiple lesions, with or without Gd enhancement, usually associated with marked edema 30 Varicella-zoster virus myelitis: an expanding spectrum.
CMV infection is rare in the immunocompetent patient, and imaging usually shows conus medullaris impairment associated with thickening, clumping, and enhancement of nerve roots and leptomeninges, often with associated long-segment cord high signal on T2 Figure Figure Cytomegalovirus acute myelitis.
Sagittal T2 WI A and comparative T1 WI post-Gd administration B demonstrated central hyperintensity with minimal expansion of long-segment cervico-thoracic lesion in the spinal cord with heterogeneous contrast enhancement. Another especially different manifestation of viral diseases is observed in the picornavirus family poliovirus, enterovirus 71 and, less commonly, Coxsackie virus A and B and in some flaviviruses, including the West Nile and dengue viruses.
This manifestation is marked by a poliomyelitis-related syndrome shown on MRI as a unilateral or bilateral hyperintensity on T2 in the anterior horns of the spinal cord across multiple segments that may be enhanced 29 HTLV-1 is endemic to certain regions and rarely shows neurologic symptoms in its carriers.
