Abstract Background Listeria monocytogenes is a gram-positive, facultative anaerobic bacillus common in the intestinal flora of many animals and humans. We describe an unusual case of meningitis by Listeria monocytogenes (LM) complicated by hydrocephalus in a child with dermatomyositis. Methods A 15-year-old girl presented to an outside hospital (OH) after a three-day history of headache, fever and was hospitalized with a diagnosis of meningitis and lumbar puncture performed. CSF sample could not be evaluated clearly due to its hemorrhagic nature. Her past medical history was significant for dermatomyositis for five years. She had received induction of IVIG five days prior. She was also taking cyclosporin A and hydroxychloroquine. She was empirically treated with intravenous cefotaxime, vancomycin, and acyclovir. She was urgently transferred to the theatre for an external shunt placement in the right lateral ventricle. The interval between the first symptoms and the diagnosis of hydrocephalus was around 4 days. CSF from this catheter showed growth of LM with sensitivity to meropenem and resistance to erythromycin, ampicillin, and sulfamethoxazole-trimethoprim. Gram staining of CSF resulted negative for bacteria. Cefotaxime was switched to intravenous meropenem. Immunological screening of cellular and humoral immunity, complement, and blood iron levels were normal. SARS-Cov2 PCR and HIV tests were negative. Herpes virus, mycobacterium tuberculosis real-time PCR, respiratory viral panel studied in the CSF sample were negative. MRI and Angio of the brain showed no abnormality. She is being followed in the pediatric intensive care unit as intubated. Results In patients who received immunosuppressive medication, L. monocytogenes should be evaluated in the differential diagnosis of central nervous system infections. Even if effective antibiotic therapy has been initiated, this case highlights the need of recognizing early hydrocephalus as a consequence of Listeria meningitis in children with neurological deterioration a few days after initial presentation. Conclusion The literature on the management and outcome of Listeria meningitis-related hydrocephalus in children is limited. Disclosures All Authors: No reported disclosures

Rosai Dorfman disease is a rare histiocytic disorder. It is also known as Sinus Histiocytosis. It is with massive lymphadenopathy involves an overproduction of a type of white blood cell. The disease is rarely associated with intracranial and intraorbital involvement. Intracranial Rosai-Dorfman can mimic meningioma. Other pathologies also underline its pathologies. Here, we report a nine-year-old boy with a history of proptosis of the right eye and presenting with multiple skull lesions. Histopathological study revealed Sphenopetroclival lesion, which features that of Rosai Dorfman Disease. His MRI scan of the brain was taken, which showed evidence of right optic nerve meningioma with sella and suprasellar extension, causing severe proptosis. The child underwent right frontotemporal craniotomy with petrosectomy and Transylvanian, subtemporal approach to multicompartmental Rosai-Dorfmans lesion. After four months, the patient had a recurrence of the disease on which chemotherapy and steroids were started, which also did not show much response while taking an MRI scan. A corticosteroid is a useful option in the Central Nervous System Rosai Dorfman disease treatment. But this patient showed a negative outcome to the treatment.

Abstract Background Merkel cell carcinoma (MCC) is a rare primary neuroendocrine cutaneous tumor, rarely metastatizing to the brain. Chronic lymphoid leukemia (CLL) is a disease predisposing to MCC. According to previous reports, headache and focal neurological deficits suggest disease progression to the brain. We present a patient with MCC whose seizure was not elicited by a cerebral metastasis, but by bone metastases compressing the brain. Case presentation The 62-year-old female patient had a history of CLL. A lesion with the appearance of an atheroma was removed from the right upper arm. Histology confirmed the diagnosis of MCC. She was admitted to the neurology department with her first GM seizure. The cranial MRI/MRA showed bone metastases in the right parietal and left frontal areas, compressing the brain. Flow cytometry of CSF did not reveal metastasis of MCC or CLL. No surgery was performed, chemotherapy was continued. Conclusions The case history of the patient was unique even among the rare cases of MCC with neurological involvement. The seizure was not elicited by a cerebral metastasis, but by bone metastases compressing the brain. In addition to patient history, clinical presentation and radiological findings enabled a suspected diagnosis preceding confirmation by laboratory methods.

Invasive craniocerebral aspergillosis, often encountered in an immunocompromised setting, is almost uniformly fatal despite radical surgical and medical management, and is frequently a necropsy finding. The authors report a unique, self-resolving clinical course of this aggressive infection in a 10-month-old infant. The infant was brought to the emergency services in altered sensorium with a 1-week history of left-sided hemiparesis, excessive irritability, and vomiting. An MRI study of the brain revealed multiple, heterogeneously enhancing lesions in the right cerebral hemisphere with mass effect. The largest lesion in the frontotemporal cortical and subcortical regions was decompressed on an emergent basis. Histopathological findings were suggestive of invasive aspergillosis, although there was no evidence of the infection in the lungs or paranasal sinuses. Computed tomography–guided aspiration of the remaining lesions and follow-up antifungal therapy were recommended. The parents, however, requested discharge without further treatment. The child was seen at a follow-up visit 3 years later without having received any antifungal treatment. Imaging showed resolution of the infection and features of Dyke-Davidoff-Masson syndrome (cerebral hemiatrophy). This report of invasive cerebral aspergillosis resolving without medical therapy is the first of its kind. Its clinicoradiological aspects are discussed in light of previously reported cases.

Flow cytometry of CSF did not reveal metastasis of MCC. Conclusions. The case history of the patient was unique even among the rare cases of MCC with neurological involvement. The seizure was not elicited by a cerebral metastasis, but by bone metastases compressing the brain. In addition to patient history, clinical presentation and radiological findings enabled a suspected diagnosis of skull metastasis of MCC compressing the brain, causing symptomatic epileptic seizures.

A 37-year-old woman, Para 5+0 presented with a 1 year history of recurrent convulsions and progressive weakness of the right side of the body. She had been treated for postpartum eclampsia in her last delivery but symptoms recurred 3 months later. Evaluation including computerized tomography scan of the brain suggested a parieto-temporal meningioma, which was completely excised at craniotomy. Histology confirmed this to be a meningioma. The patient was well at 8 months of follow up. The growth of meningiomas may increase during pregnancy due to presence of receptors for progestational hormones in the tumour and the meningioma may become symptomatic in pregnancy, presenting as eclampsia. Close follow up of patients with eclampsia is necessary to identify neurological features that may lead to a diagnosis of meningioma. Early diagnosis is essential if a good outcome is to be ensured.

We report a fatal case of a chromoblastomycosis-like infection caused by a novel species ofFonsecaeain a 52-year-old immunocompetent Caucasian male from an area of chromoblastomycosis endemicity in Brazil. The patient had a 30-year history of slowly evolving, verrucous lesions on the right upper arm which gradually affected the entire arm, the left hemifacial area, and the nose. Subsequent dissemination to the brain was observed, which led to death of the patient. The internal transcribed spacer (ITS) and partial large subunit (LSU),BT2, andCDC42genes of the isolates recovered from skin and brain were sequenced, confirming the novelty of the species. The species is clinically unique in causing brain abscesses secondary to chromoblastomycosis lesions despite the apparent intact immunity of the patient. Histopathologic appearances were very different, showing muriform cells in skin and hyphae in brain.

Background: Myeloid sarcoma (MS) is a rare solid tumour made of myeloblasts or immature myeloid cells in an extramedullary site or in bone, associated with systemic hematologic neoplasms. When they occur in the brain parenchyma, they can often be misdiagnosed. Methods: The authors report a case of a 4-year old boy 6 months out of remission from AML, presenting with a short history of headaches and vomiting, and found to have a heterogenous contrast-enhancing lesion in the right cerebellar hemisphere, with differential diagnosis of myeloid sarcoma, astrocytoma, medulloblastoma and ATRT. Preliminary diagnosis was made flow cytometry from an intraoperative biopsy. The patient had a long course of chemotherapy and radiation, but eventually died from the systemic burden of his AML. Results: The authors present a literature review on 178 published cases of CNS myeloid sarcomas, and their radiological presentation and the basis of immunohistochemical and pathological diagnosis is discussed. Conclusions: Diagnosis rests on a combination of immunohistochemistry and histopathology of biopsied tissue. Surgical resection is controversial, especially given the efficacy of chemotherapy and radiation, and prognosis remains unclear. As with all uncommon and rare clinical entities, further investigation is warranted to determine prognosis and optimal management of CNS myeloid sarcomas.

This publication reviews the steps in the path towards obtaining a complete image of the brain. Up to the 1920s, plain X-ray films could demonstrate only calcified tumors, shifts in midline position of a calcified pineal gland due to a mass in the cranium, or foreign metallic objects within the skull. Walter Dandy reported in 1918 that he visualized cerebral ventricles by introducing air as a contrast agent through a trocar into one of the occipital lobes or the right frontal horn of the ventricular system. Dandy localized lesions that distorted or shifted the ventricles. In 1920, Dandy placed air by lumbar puncture into the spinal subarachnoid space that could visualize the brain and entire ventricles. Antonio Egas Moniz with the assistance of his neurosurgeon colleague, Almeida Lima, obtained X-ray images of cerebral arteries of dogs and decapitated human heads from corpses after injecting strontium bromide into their carotid arteries. Satisfied by these experiments, Moniz injected strontium bromide directly into carotid arteries of five patients which failed to show intracranial vessels. In the sixth patient, intracranial arteries were outlined but that patient died of cerebral thrombosis presumably due to the hyper- osmolality of that contrast agent. Finally, on June 18, 1927, Moniz injected 22% sodium iodine into a 20-year-old man and obtained clear visualization of his carotid artery and intracerebral branches after temporarily occluding the artery with a ligature.

Abstract Background: We investigated intracerebral fiber bundles using a tract-based spatial statistics (TBSS) analysis of diffusion tensor imaging (DTI) datato investigate microstructural integrity in patients with episodic (MO) and chronic migraine (CM).Methods: We performed DTI in 19 patients with MO within interictal periods, 18 patients with CM without any history of drug abuse, and 18 healthy controls (HCs) using a 3T magnetic resonance imaging scanner. We calculated diffusion metrics, including fractional anisotropy (FA), axial diffusion (AD), radial diffusion (RD), and mean diffusion (MD).Results: TBSS revealed no significant differences in the FA, MD, RD, and AD maps between the MO and HC groups. In comparison to the HC group, theCM group exhibited widespread increased RD (bilateral superior [SCR] and posterior corona radiata [PCR], bilateral genu of the corpus callosum [CC], bilateral posterior limb of internal capsule [IC], bilateral superior longitudinal fasciculus [LF]) and MD values (tracts of the right SCR and PCR, right superior LF, and right splenium of the CC). In comparison to theMO group, theCM group showed decreased FA (bilateral SCR and PCR, bilateral body of CC, right superior LF, right forceps minor) and increased MD values (bilateral SCR and right PCR, right body of CC, right superior LF, right splenium of CC, and right posterior limb of IC). Conclusion: Our results suggest that chronic migraine can be associated withthe widespread disruption of normal white matter integrity in the brain.

A two-year-ten-month-old entire female fancy rat was evaluated for acute-onset neurological signs following a two-month history of lethargy and behavioural changes. Physical examination revealed generalised muscle atrophy. Neurological examination localised the lesion likely to the right thalamus based on suspected left unilateral hemineglect. The patient was euthanased over quality-of-life concerns, and postmortem MRI of the brain was performed, followed by postmortem examination. This showed a lesion in the region of the pituitary which was T1 hyperintense to the brain, T2 isointense to the white matter and hypointense on gradient echo sequences, suggesting subacute haemorrhage. The authors described the clinical presentation and imaging features (MRI) of suspected pituitary apoplexia secondary to a pituitary macroadenoma in an aged female rat. Of particular interest are the findings of unilateral hemineglect and blooming artefact on MRI gradient echo sequences that lead to suspicion of pituitary apoplexia confirmed on postmortem examination.
