Long coronavirus disease (COVID) - commonly defined as symptoms and/or long-term effects that persist for at least 3 months after acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and cannot be explained by an alternative diagnosis - is a complex, multifaceted and heterogeneous disease that affects many organ systems, including the kidney. COVID-19 can cause acute kidney injury, and several studies have reported an increased risk of chronic kidney disease (CKD) following COVID-19, suggesting that CKD can be a manifestation of long COVID. Furthermore, patients with CKD are at an increased risk of severe COVID-19 and of long COVID.

Background: Varicella zoster virus (VZV) infection is a common viral illness in children, typically manifesting as chickenpox and having a benign, self-limiting course. However, severe neurological complications-such as vasculitis resulting in intracranial hemorrhage-although rare, can occur and are associated with significant morbidity and mortality.
Case Presentation: We present the case of a previously healthy 7-year-old boy who developed intracranial hemorrhagic vasculitis 14 days after a primary VZV infection.

Staphylococcal infections remain a prominent cause of hospital- and community-acquired infections in the United States. Glomerulonephritis with predominant Immunoglobulin A (IgA) deposition following staphylococcal infection has been described as IgA-dominant postinfectious glomerulonephritis (IgA-PIGN). This clinical entity can mimic Henoch-Schönlein purpura nephritis (HSPN) given that it may also be preceded by staphylococcal infection, have similar kidney biopsy findings, and present with similar signs and symptoms.

Rationale: Delayed cerebral infarction (DCI) is a rare but devastating complication of bacterial meningitis that is characterized by an initial good recovery followed by sudden deterioration several days after presentation. The potential mechanisms underlying DCI encompass postinfectious vasculitis, vasospasm, and cerebral thrombosis. Sequential magnetic resonance angiography and characteristic high-resolution magnetic resonance patterns are helpful in discerning the cause of DCI.

Introduction: As detailed in the first part of this review, post-infectious vasculitides are a wide and complex category, including several clinical, microbiological and neuroradiological patterns. In order to raise the suspicion for diagnosis, the knowledge of two different neuroradiological issues is needed, i.e.
