Internal drainage of cerebrospinal fluid utilizing a mechanical tube has been an increasingly common and effective procedure for the relief of non-communicating hydrocephalus with intracranial tumor. However, several cases have recently been reported in which extraneural metastases of the tumor were initiated through the shunt tube implanted. The purpose of this paper is to present two cases with malignant brain tumor metastasizing extraneurally through ventriculoperitoneal shunt, and to review the reported cases in the literature. Case 1 The patient, a 9-year-old boy, had been suffering from headache and vomiting for 3 months prior to admission to the Neurosurgical Clinic, Gumma University Hospital. On admission, he had choked discs and cerebellar dysfunction with a staggering gait. The clinical diagnosis was a 4th ventricle tumor. On November 29, 1971, a suboccipital craniectomy was performed. A medullary tumor in the 4th ventricle was partially removed, and ventriculoperitoneal shunt was also performed. Subsequently postoperative irradiation was given, and the symptoms were abated. Histological diagnosis was ependymoblastoma. Thirteen months later, he was again admitted because of visual disturbance, psychic change and pituitary hypofunction. Bilateral frontal craniotomy revealed a large mass over the midline of the anterior skull base, accompanied by numerous meningeal neoplastic deposits. The tumor was partially removed and histologically proven to be meningeal metastases of ependymoblastoma. Irradiation was again given and the symptoms improved. But the 4th ventricle tumor recurred 5 months after the 2nd operation, and then a massive intraperitoneal effusion appeared. Cytological examination revealed clusters of tumor cells in the ascites. The patient died on September 8, 1974, namely 22 months after the ventriculoperitoneal shunt was implanted. Postmortem examination showed a solid tumor in the 4th ventricle which was accompanied by diffuse meningeal dissemination, and metastases were present throughout the peritoneal surface...

Neurosyphilis, a sexually transmitted disease that can cause neurologic damage, has become increasingly prevalent in the AIDS era. HIV carriers can contract neurosyphilis without the presence of other concurrent opportunistic infections. Because MR findings of neurosyphilis are seldom reported, we retrospectively reviewed and evaluated contrast-enhanced MR images of six young (average age, 33 years) HIV-positive men with high serum and CSF VDRL titers indicative of neurosyphilis. All six patients tested negative for concurrent opportunistic infections. Five patients had acute or subacute strokelike symptoms involving the basal ganglia or middle cerebral arteries; one had a parietal convexity mass mimicking meningioma with headache and ataxia. Contrast-enhanced MR images showed patchy enhancement involving the basal ganglia and middle cerebral artery territories in the first five patients and the convexity mass in the sixth patient. On the basis of brain biopsy, a convexity mass was diagnosed in the patient with syphilitic gumma. The imaging findings of the remaining five patients represented ischemic infarct caused by meningovascular syphilis. After penicillin treatment, serum and CSF VDRL titers decreased, and neurologic signs and symptoms improved in all six patients. A follow-up MR study in the patient with the gumma showed that the lesion resolved almost completely. In young HIV patients with stroke symptoms or a convexity mass, neurosyphilis should be considered. Contrast-enhanced MR can reveal the extent of involvement by neurosyphilis and should be used to facilitate diagnosis and proper treatment.

A 75-year-old male presented with the complaint of headache. Magnetic resonance (MR) imaging demonstrated a low-signal intensity area on both T1- and T2-weighted images with ring-like enhancement and adhesion of the dura appearing as dural tail sign. Follow-up MR imaging demonstrated spontaneous regression, so the preoperative diagnosis was malignant lymphoma. Histological examination revealed typical granuloma. Treponema pallidum hemagglutination assay tests of serum and cerebrospinal fluid were positive for active syphilis. The enhanced mass totally disappeared after 4 months of erythromycin therapy. The final diagnosis was cerebral gumma. The incidence of syphilis is increasing, so cerebral gumma should be included in the differential diagnosis of hypovascular tumors that involve both the parenchyma and dura even in the presence of spontaneous regression.

The brain gumma is a rare manifestation of the tertiary stage of syphilis. A case of neurosyphilitic gumma was confirmed by the Treponema pallidum polymerase chain reaction in a 46-year-old HIV-positive homosexual man. The patient presented with a severe headache and was hospitalized. A computed tomography scan was performed which revealed a left frontal lobe mass. Lymphoma was suspected. However, infectious disease diagnostics were performed on the cerebrospinal fluid that included investigations for syphilis and other microbiological agents such as Toxoplasma gondii. This revealed a reactive venereal disease research laboratory test, a reactive syphilis rapid plasma reagin and a reactive T. pallidum particle agglutination test. The patient was treated for syphilis till complete recovery.

Syphilis, along with the recent increase of human immunodeficiency virus (HIV) patients, has also been on the rise. It has a broad spectrum of clinical manifestations, among which cerebral gumma is, a kind of neurosyphilis, however, it is rare and can be cured by penicillin. Thus, cerebral gumma needs to be differentially diagnosed from other brain masses that may be present in syphilis patients. We have experienced a case where the patient was first suspected of brain tumor, but confirmed by surgery to be cerebral gumma due to neurosyphilis. This is the first such case encountered in Korea, therefore, we report it here in. A 40-year old woman complaining of headaches was found to have a brain mass on her CT scans and MRI. Suspecting a brain Tumor, a resection was performed on the patient, and histological results revealed that the central portion of the mass contained necrotic material and the peripheral region was infiltrated with plasma cells. Warthin-Starry staining of the region revealed spirochetes, and the patient was thus diagnosed as brain gumma. Venereal Disease Research Laboratory (VDRL) of cerebrospinal fluid (CSF) was reactive. After an operation, penicillin-G at a daily dose of 24 x 10(6) U was given for 10 days from post-operative day 10, and thereafter, the mass disappeared.

We report a case of young immunocompetent woman who was presented with a left parieto-temporal mass as the first and single manifestation of syphilis. A 23 year-old woman with no significant past medical history was reffered to our hospital due to 3 month history of headache. She had a single unprotected sexual intercourse with a promiscuous man 6 month before the time of admission. Physical and neurological examinations revealed no obvious abnormalities. A brain tumor was firstly suggested according to the findings of brain magnetic resonance imaging (MRI). However, the serologic and cerebrospinal fluid test of syphilis proved to be positive, syphilitic gumma was most likely suspected. She responded dramatically to benzylpenicillin potassium. Cerebral syphilitic gumma is a rare manifestations of the neurosyphilis. Treponemal invasion of the cerebrospinal fluid occurs in approximately 25 to 60% of patients after the infection, but most cases spend asymptomatic. Cerebral gumma should be considered in differential diagnosis of any intracranial mass lesions, even in the early syphilitic stages.

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.

A 45-year-old man was admitted with severe headache and left-sided weakness, which worsened over 1 week. Brain imaging revealed a small lesion close to the sagittal sinus in the right frontal lobe with severe perilesional edema and showed enhancement on both CT and MRI obtained with contrast. Serological findings were positive for toluidine red unheated serum test (TRUST) positivity and Treponema pallidum particle agglutination assay. The patient was first suspected of having a malignant brain tumor and subsequently received emergency craniotomy. Brain biopsy suggested a diagnosis of syphilitic cerebral gumma; meanwhile the postoperative CSF TRUST titer was positive, and the patient's improvement with high-dose intravenous aqueous crystalline penicillin further supported this etiology. Finally, the lesion on the right frontal lobe had disappeared during the follow-up imaging examination and the myodynamia of the left limbs gradually improved. The authors recommend that diagnostic penicillin treatment should be first implemented. When a patient's history, clinical manifestations, syphilis serology, CSF examination, and other physiological changes indicate a diagnosis of syphilitic cerebral gumma, there is no doubt that surgery should be performed in patients with acute intracranial hypertension, but unnecessary craniotomy should be avoided as far as possible.
