Cerebral syphilitic gumma: a case report and review of the literature

Gummatous neurosyphilisin an HIV-negative patient: Case report

Syphilis is a chronic infectious disease, which dates back to the XV century and is caused by the spirochete treponema pallidum, capable of invading the central nervous system in any of its stages- Its incidence has increased in parallel to the HIV/AIDS pandemic, and the synergism between both pathologies is such. that it has become a public health problem in recent years. Here we present the case of a 31-year-old female patient, who consulted for headache associated with decreased visual acuity and provided an unenhanced head CT showing hypodense lesions in both thalamic regions, serological tests for syphilis were reactive and those for HIV were not reactive. The brain MRI with spectroscopy was reported in favor of cerebral toxoplasmosis, which was later ruled out with a study of cerebrospinal fluid. Management with penicillin G sodium IV for 6 weeks was indicated, achieving complete imaging resolution of her lesions.

Cerebral syphilitic gumma misdiagnosed as brain abscess: A case report

BACKGROUND

Cerebral syphilitic gumma is a relatively rare clinical disease. Its clinical manifestations are non-specific, and the imaging manifestations are similar to other intracranial occupying lesions, often misdiagnosed as tumors or abscesses. There are few reports on this disease in the relevant literature. To our knowledge, we have reported the first case of cerebral syphilitic gumma misdiagnosed as a brain abscess.We report this case and provide useful information for clinical doctors on neurosyphilis diseases.

CASE SUMMARY

We report the case to explore the diagnostic essentials of cerebral syphilitic gumma and attempt to mitigate the rates of misdiagnosis and missed diagnosis by equipping physicians with knowledge of neurosyphilis characteristics. The clinical diagnosis and treatment of a patient with cerebral syphilitic gumma were reported. Clinical manifestations, classifications, and diagnostic points were retrospectively analyzed. The patient was admitted to the hospital with fever and limb weakness. Brain magnetic resonance imaging showed multiple space-occupying lesions and a positive serum Treponema pallidum gelatin agglutination test. The patient was misdiagnosed as having a brain abscess and underwent a craniotomy. A postoperative pathological diagnosis of syphilis gumma was made. The patient improved and was discharged after penicillin anti-syphilis treatment. Follow-up recovery was satisfactory.

CONCLUSION

Cerebral syphilitic gumma is rare in clinical practice, and it is often misdiagnosed and missed. Clinical diagnosis should be considered in combination with multiple examinations.

Cerebral syphilitic Gumma in the modern era: a report of an unusual case and brief review of recent published reports

BACKGROUND

Cerebral syphilitic gummas are rare. However, numerous case reports on them have been published recently, consistent with the resurgence of syphilis and its accompanying atypical manifestations. We here present a patient with a cerebral syphilitic gumma and an unusual clinical course and review recent case reports.

CASE PRESENTATION

A 49-year-old woman had a generalised seizure and was found by computed tomography and magnetic resonance imaging to have a brain mass that mimicked a brain abscess or malignant tumour. Further imaging with magnetic resonance spectroscopy and positron emission tomography did not contribute further to the differential diagnosis. Because treatment with ceftriaxone was ineffective, the lesion was resected. Serological tests on serum and cerebrospinal fluid were positive for syphilis and histopathological examination of the operative specimen revealed a syphilitic gumma. Antibiotic treatment is preferred over invasive interventions for cerebral syphilitic gumma. However, as in our case, radical resection is required when antibiotic treatment is ineffective.

CONCLUSIONS

It has recently been reported that the prevalence of syphilis is increasing in older individuals, including in patients without HIV infection or prior treatment for early syphilis. Though advanced imaging and molecular biological techniques are often used to help make a diagnosis, they are of limited value. Because the clinical and imaging features are nonspecific, some neurosurgeons do not include cerebral syphilitic gummas in their differential diagnoses. It is vital that this possibility be considered when a patient has a tumour-like cerebral mass and serum positivity for syphilis.

Syphilitic Gummata in the Central Nervous System: A Narrative Review and Case Report about a Noteworthy Clinical Manifestation

Infection with Treponema pallidum is on the rise. In this narrative literature review, we show that the incidence of rare manifestations of syphilis, such as intracerebral gummata, is increasing and should be considered in the differential diagnosis of intracerebral lesions. With the exemplary case that we present here, we aim to raise awareness of the resurgence of this disease, which should be considered in the differential diagnosis of intracerebral lesions, especially for patients who have a risk profile for syphilis, and serological testing for T. pallidum prior to surgery should be discussed in order to avoid an unnecessary operation.

Gummatous penile syphilis

•

Syphilitic gumma should be included in the differential diagnosis of penile lesion, even in the absence of recent intercourses.

•

A penile biopsy should always be considered when planning an invasive surgery.

•

Gummatous syphilis can be treated using IV Penicillin.

Syphilitic gumma involving the penis is a rare manifestation of tertiary syphilis. Only seventeen cases have been reported in the literature. It can mimic other diagnoses such as penile carcinoma. We report a case of a 56 year old male that had been sexually abstinent for over 10 years and presenting with a 4 cm painful penile lesion with clinically palpable bilateral inguinal nodes with no prior history of sexually transmitted diseases (STDs). A positron emission tomography-computed tomography scan identified the penile mass as being hypermetabolic and suspicious for penile carcinoma. Several inguinal and pelvic lymph nodes were also found to be suspicious for penile carcinoma. A penile biopsy was proposed and declined by the patient as he opted for a partial penectomy. The surgery was performed for diagnostic and palliative purposes. Histopathological studies revealed the presence of polymorphous, granulomatous, epitheloid inflammatory infiltrate with giant cells. Additional microbiologic testing confirmed the diagnosis of tertiary syphilis, presenting as gummatous syphillis associated with neurosyphilis. The patient was treated with intravenous penicillin and had adequate clinical clinical and serologic 12 months following treatment. Gummatous syphillis is a rare entity, but should be considered in the differential diagnosis of a penile lesion. To rule out this possibility, a biopsy should always be performed prior to invasive penis surgery.

Multiple cerebral syphilitic gummas mimicking brain tumor in a non-HIV-infected patient: A case report

We present a unique case of symptomatic early neurosyphilis in a non-HIV-infected patient. A 47-year-old man with a history of diabetes mellitus presented with generalized seizures. He did not manifest any neurological deficits. At first, multiple brain tumors were suspected based on findings from magnetic resonance imaging of the brain. However, serological and cerebrospinal fluid tests for syphilis yielded positive results, and the masses were reduced using amoxicillin. Multiple cerebral syphilitic gummas were therefore diagnosed. High-dose penicillin therapy was initiated and syphilitic gummas disappeared after five months. Treponema pallidum could invade the central nervous system at an early phase, and sometimes may be difficult to distinguish from malignant brain tumor. If intracranial lesions are identified in a syphilis-infected patient, cerebral syphilitic gumma should be considered as a differential diagnosis.

Diagnosis and Treatment of Cerebral Syphilitic Gumma: A Report of Three Cases

Cerebral syphilitic gumma is very rare and is often pathologically confirmed following surgery. This study reports three patients with cerebral syphilitic gumma. The first case was a 62-year-old man who was admitted to our hospital due to speech arrest for 10 hours. Head MRI showed a nodular signal shadow with a significant enhancement and a significant centerline shift. He subsequently received surgery, and cerebral syphilitic gumma was confirmed by postoperative pathology. The second patient was a 66-year-old man who was admitted to our hospital due to complaints of gradually decreasing right eye vision and headache for nearly 50 days. Enhanced MRI at admission indicated irregular clumping of high-signal mixed with low-signal foci on the frontal lobe. Subsequently, he was operatively treated and was confirmed to have cerebral syphilitic gumma by postoperative pathology. The third patient was a 37-year-old man who was admitted to our hospital due to dizziness for approximately 15 days. Head MRI indicated a slightly abnormal lamellar and longer T1, T2 signal shadow on the left side. He did not receive surgery, and his symptoms disappeared after anti-syphilitic treatment. Hence, we recommend a critical interpretation of preoperative imaging data, understanding the unique changes that arise in the brain that can be detected through imaging, and an analysis of the patient history and laboratory tests to re-evaluate the value of surgery, with the ultimate goal of performing a stabilizing treatment for cerebral syphilitic gumma.

Cerebral Syphilitic Gumma Misdiagnosed as a Malignant Brain Tumor

Syphilitic gumma involvement of the central nervous system is extremely rare and frequently misdiagnosed. The authors report a patient of a cerebral syphilitic gumma resembling a malignant brain tumor in a 62-year-old male. He was first suspected of a malignant brain tumor, but the pathological diagnosis was cerebral syphilitic gumma. This patient with unusual findings illustrates the clinical manifestations, imaging, and therapeutic aspects of cerebral syphilitic gumma.

Other central nervous system infections: cytomegalovirus, Mycobacterium tuberculosis, and Treponema pallidum

Human immunodeficiency virus (HIV)-infected individuals are particularly susceptible to several central nervous system infections: human cytomegalovirus, which may cause encephalitis, ventriculitis, polyradiculitis, or polyradiculomyelitis; Mycobacterium tuberculosis, which can cause meningitis or space-occupying lesions; and Treponema pallidum subspecies pallidum (T. pallidum), which affects the meninges, cerebrospinal fluid, cranial nerves, and vasculature in early neurosyphilis, and additionally the brain and spinal cord parenchyma in late neurosyphilis. Central nervous system cytomegalovirus infection is seen in HIV-infected individuals with very advanced immunosuppression. Its prognosis is poor and optimal therapy has not been determined. Tuberculous meningitis has a high mortality in those also infected with HIV, especially in the developing world, and better therapies are urgently needed. As the rates of syphilis increase in the developed world, neurosyphilis and in particular ocular syphilis are increasingly reported. The likelihood of all three of these central nervous system infections is decreased in individuals who receive potent antiretroviral therapy.

Changes in neurosyphilis presentation: a survey on 286 patients

Although neurosyphilis (NS) keeps plaguing worldwide, often with oligosymptomatic and atypical manifestations, the most recent reports fail to provide useful information, like details of the clinical history and even of the previous early therapy. We conducted a survey of the literature of the last 5 years on the clinical presentation of NS, recording the aforementioned inaccuracies. One hundred and thirty-seven articles were collected, reporting on 286 patients. General paresis was the commonest form (49%), often manifesting with cognitive impairment and psychiatric symptoms. Syphilitic meningitis was found in 63 patients (22%), mainly with ocular or auditory involvement. Meningovascular and tabetic form were both found in 12% of cases. Gummatous and epileptic manifestations were rare. Perusal of the literature confirms that NS prevalence is increasing, often with manifestations that are atypical for timing and type of lesions. Unfortunately, many articles are lacking of critical information, like an accurate clinical history and timing of the therapy making difficult to assess the effectiveness of penicillin in preventing NS.
