Background: Central nervous system (CNS) aspergillosis is more often met in patients with expressed immune suppression. Still, in 50% of cases of meningitis caused by Aspergillus spp., it is observed in patients without expressed immune suppression. The prognosis of CNS aspergillosis is unfavorable with the general rate of lethality around 70%. Case Description: Clinical case of a 58-year-old man who developed an Aspergillus abscess in the chiasmosellar region and an associated mycotic aneurysm of the right middle cerebral artery (MCA) and intracerebral hemorrhage. Microsurgical clipping of the fusiform-ectatic aneurysm of the right MCA in the conditions of rupture was performed. An extra-intracranial micro anastomosis was formed on the right. An open biopsy of the neoplasm in the chiasmosellar region was made. The neoplasm was yellow and destroyed the bone plate of the skull base. Biopsy results: Mycotic lesion (aspergillosis). The analysis of surgical treatment for mycotic aneurysms in the acute period of hemorrhage in patients with aspergillosis revealed a high rate of lethality. The issue of the feasibility and effectiveness of complicated revascularization interventions in the patients with hemorrhage and aspergillosis remains unsolved. Conclusion: The lack of generally accepted tactics of the treatment of this pathology requires further studies and systemic analysis. A high risk of the lethal outcome in patients with invasive mycotic infection and rupture of mycotic aneurysm highlight the importance of timely diagnostics and the beginning of antimycotic therapy. WThe issue of the evaluation of the revascularization methods effectiveness in patients after surgical treatment of a mycotic aneurysm associated with cerebral aspergillosis remains poor.

Listeriosis is an infectious disease caused by Listeria monocytogenes microorganisms. A human can catch an infection through fecal-oral, aerogenous, or transplacental route. The listeriosis incidence in Ukraine is sporadic, single cases are not related to each other. Listeriosis is characterized by a high rate of mortality and polymorphism of clinical manifestations. The symptoms of the disease are multiple-organ: damage to the central nervous system, septic symptoms, aborts, mastitis; listeriosis can also be subclinical. The disorders of the central nervous system are associated with meningitis, meningoencephalitis, or brain abscess. The importance of the problem of diagnosis and treatment of listeriosis derived from the disease sporadicity, polymorphism of its manifestations, difficulties in etiological verification of the diagnosis. The case described is specific due to the diagnostic mistake: a child was not diagnosed with sepsis. Listeriosis in this child had a progressive course with sepsis development. Listeriosis is a rare infection, therefore it was difficult to suggest this particular infection intra vitam.

Postmortem Finding

Aneurysms which are formed when the wall of an artery is weakened from within by infection are generally called "mycotic" even though the most common infection is by pyogenic bacteria rather than by fungi. This report documents the unusual and unexpected postmortem finding of an awn of a grass inflorescence as the nidus for the pathogenesis of a mycotic aneurysm of the right middle cerebral artery. Such an etiology should typically be termed "phytotic." Case Summary A previously healthy 5½-year-old boy was treated for otitis media three weeks prior to admission. This responded to a combination of intramuscularly and orally administered antibiotics.

The C-type lectin Mincle is implicated in innate immune responses to sterile inflammation, but its contribution to associated pathologies is not well understood. Herein, we show that Mincle exacerbates neuronal loss following ischemic but not traumatic spinal cord injury. Loss of Mincle was beneficial in a model of transient middle cerebral artery occlusion but did not alter outcomes following heart or gut ischemia. High functional scores in Mincle KO animals using the focal cerebral ischemia model were accompanied by reduced lesion size, fewer infiltrating leukocytes and less neutrophil-derived cytokine production than isogenic controls. Bone marrow chimera experiments revealed that the presence of Mincle in the central nervous system, rather than recruited immune cells, was the critical regulator of a poor outcome following transient middle cerebral artery occlusion. There was no evidence for a direct role for Mincle in microglia or neural activation, but expression in a subset of macrophages resident in the perivascular niche provided new clues on Mincle's role in ischemic stroke.

Abstract Background To report a case of acute exudative polymorphous paraneoplastic vitelliform maculopathy in a patient with a history of choroidal melanoma, with metastases to the pancreas, liver, and central nervous system. Case presentation A 63-year-old patient, with a history of enucleation of the right eye due to choroidal melanoma, complained of progressive visual loss during a follow-up visit. Fundoscopic examination revealed multiple small areas of serous retinal detachment scattered throughout the posterior pole and ancillary tests confirmed the diagnosis of acute exudative polymorphous paraneoplastic vitelliform maculopathy (AEPPVM). Screening for systemic metastases showed pancreatic, hepatic, and central nervous system involvement. Conclusions We describe a rare case of acute exudative polymorphous paraneoplastic vitelliform maculopathy, which should be considered in patients with or without a history of melanoma, who have vitelliform retinal detachments. Nevertheless, no previous reviews of literature have shown a correlation between AEPPVM and pancreatic metastasis.

Abstract BACKGROUND Primary central nervous system lymphoma (PCNSL) are very rare in children. CLINICAL CASE: An 11-year-old male presented with a 2 months history with myoclonic movements in the upper right limb, and a sudden frontal headache, gait disturbance due to right hemiparesis and an ipsilateral convulsive episode. Upon admission he had critical condition, with hypertensive skull syndrome, Glasgow of 12, Karnofsky 40%, right hemiparesis, swallowing disorder, facial paralysis, and loss of photo motor reflex and unilateral amaurosis. A CT and MRI showed a huge tumor mass in the left tempo-parietal region, infiltrating the white matter and shifting the midline. A Tumor biopsy was done, and reported diffuse small cell non-Hodgkin lymphoma of high-grade, Burkitt type. Systemic lymphoma workup was negative. He received six cycles of chemotherapy based on high dose methotrexate, rituximab and triple intrathecal.After the second cycle an ophthalmologic evaluation was done, and found infiltration to the right retina, for which 6 cycles of intra vitreous chemotherapy with methotrexate were applied, he showed an excellent response, and recovered all his neurological functions except that right hemianopia persist. Control MRI showed partial response at 2nd cycle and complete response after the 4th cycle. No Radiation was performed. CONCLUSION This report highlights the fact that pediatric PCNSL may be effectively treated by a combination of HDMTX and rituximab-based chemoimmunotherapy without irradiation. Lack of awareness of this rare entity may lead to extense resections of brain, and potential permanent secuelae that were avoided in this illustrative case.

Acute disseminated encephalomyelitis (ADEM) is a rare immune-mediated inflammatory and demyelinating disorder of the central nervous system. Its characteristic perivenular demyelination and inflammation aid in the differential diagnosis with other inflammatory demyelinating diseases. Here, we present a clinical case of ADEM, summarize its histological hallmarks, and discuss pitfalls concerning the most important neuropathological differential diagnoses.

ABSTRACT:Spinal dysraphism is an umbrella term that encompasses a number of congenital malformations that affect the central nervous system. The etiology of these conditions can be traced back to a specific defect in embryological development, with the more disabling malformations occurring at an earlier gestational age. A thorough understanding of the relevant neuroembryology is imperative for clinicians to select the correct treatment and prevent complications associated with spinal dysraphism. This paper will review the neuroembryology associated with the various forms of spinal dysraphism and provide a clinical-pathological correlation for these congenital malformations.
