BACKGROUND: Pulmonary hematoma is most often caused by thoracic trauma. However, rare cases of pulmonary hematoma without any obvious cause are sometimes reported, when the condition is referred to as spontaneous or idiopathic pulmonary hematoma. Herein, we report a very rare case-to the best of our knowledge, this is the first case of pulmonary hematoma associated with diffuse pulmonary ossification requiring emergency treatment reported in the English literature. CASE PRESENTATION: Our patient was a 44-year-old man with a history of IgA nephropathy and had no history of trauma or anticoagulant use...

BACKGROUND: Primary Angiitis of the Central Nervous System (PACNS) is a rare cause of CNS vasculitis that should be included as part complete differential diagnosis, especially in cases with suggestive imaging findings and an absence of secondary causes for CNS vasculitis. CASE PRESENTATION: We describe a case of a 47-year-old previously healthy Caucasian male presenting with rapid progression of encephalopathy and fevers. Extensive infectious, autoimmune, and imaging workups were unrevealing...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by the production of ANCAs and systemic necrotizing vasculitis in small vessels. Disordered regulation of neutrophil extracellular traps (NETs) is critically involved in the pathogenesis of AAV. NETs are web-like DNA decorated with antimicrobial proteins; they are extruded from activated neutrophils. The principal degradation factor of NETs in vivo is DNase I; however, NETs resistant to DNase I can persist in tissues and lead to the production of ANCAs...

BACKGROUND: Arterial ischemic stroke is rare in childhood. Often, the diagnosis is made after considerable delay. A thorough workup to pinpoint the underlying etiology is necessary, as a correct diagnosis is the determining factor in treatment decision. In case of primary angiitis of the central nervous system, treatment with corticosteroids and immunosuppressive agents is indicated. CASE STUDY: We described an eleven-year-old boy who presented at the age of six years with left hemiparesis and hemianopia...

Primary angiitis of the central nervous system (PACNS) is a rare disease with various clinical presentations. It is the preferred name for vasculitis that is confined to the central nervous system (CNS) and is often considered a diagnosis of exclusion in vascular or inflammatory CNS diseases. This case describes a 46-year-old right-handed female with a past medical history of hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus type two (DM2), obesity, and hemorrhagic stroke who was transferred from an outside facility after a one-month hospitalization to be evaluated for CNS vasculitis...

OBJECTIVES: To further improve the distinction between primary angiitis of the CNS (PACNS) and reversible cerebral vasoconstriction syndrome (RCVS). METHODS: We compared 2 large French cohorts of patients with PACNS (n = 110, retrospectively and prospectively enrolled) and RCVS (n = 173, prospectively enrolled). RESULTS: Patients with RCVS were predominantly female ( p < 0.0001), with migraines ( p < 0.0001), and were more often exposed to vasoactive substances ( p < 0...

BACKGROUND: Peripheral blood mononuclear cells (PBMNCs) and purified CD34+ cells (PCCs) are increasingly being used at treating no-option critical limb ischaemia (NO-CLI). We aimed to compare the efficacies and uncover the advantages associated with each treatment approach. METHODS: A randomised single-blinded non-inferiority trial (Number: NCT 02089828) was performed. NO-CLI patients were 1:1 randomised to the PBMNCs and PCCs groups, and compared in relation to safety and efficacy outcomes...

OBJECTIVES: Clinical involvement of the nervous system is uncommon during sarcoidosis. Cerebrovascular events are rarely reported during sarcoidosis and may be confused with primary angiitis of the central nervous system. The characteristics and outcomes of cerebrovascular events during sarcoidosis have not been well-evaluated. PATIENTS AND METHODS: We conducted a retrospective case series in our institution with an updated review of the literature from 1962 to 2017 to characterize the clinical presentation, imaging, histology and outcomes of stroke that were thought to be causally related to sarcoidosis...

PURPOSE OF REVIEW: Primary central nervous system angiitis (PCNSA) is a rare disease. Varying clinical pictures coupled with lack of sensitive and specific diagnostic tests lead to challenges in management of these patients. This unfortunately may lead to both under- or over-diagnosis and unnecessary treatment. It is important to recognize the different conditions that may mimic the clinical and radiologic presentation. We present a contemporary literature review that should update physicians who encounter this patient population...

Amyloid beta-related angiitis (ABRA) is a subtype of cerebral amyloid angiopathy-related inflammation, with distinctive pathology and prognosis compared with cerebral amyloid angiopathy (CAA). On a spectrum of increasing severity, ABRA is considered to be in-between the less aggressive inflammatory-CAA and the more severe primary central nervous system (CNS) angiitis. Whereas retinal pathological changes were described in subjects with primary or secondary CNS angiitis, and non-inflammatory CAA, bilateral posterior pole superficial and peripapillary retinal hemorrhages have not been reported as initial signs in patients with pathology-confirmed ABRA, accompanying neurological spells and characteristic neuroimaging findings...

Primary angiitis of the central nervous system (PACNS) represents a rare inflammatory disease affecting the brain and spinal cord. Stroke, encephalopathy, headache and seizures are major clinical manifestations. The diagnosis of PACNS is based on the combination of clinical presentation, imaging findings (magnetic resonance imaging and angiography), brain biopsy, and laboratory and cerebral spinal fluid (CSF) values. PACNS can either be confirmed by magnetic resonance angiography (MRA)/conventional angiography or tissue biopsy showing the presence of typical histopathological patterns...

A previously healthy, 77-year-old woman presented with gradual cognitive decline and acute gait imbalance. On admission, despite no obvious paralysis, she tilted to the right. Her Mini-Mental State Examination score was slightly low (23/30). Gadolinium-enhanced, high-resolution T1 -weighted MRI showed abnormal arterial wall enhancement at the bilateral middle cerebral and right internal carotid arteries. The combination of arterial and parenchymal enhancement limited to the central nervous system (CNS), normal laboratory data including soluble interleukin-2 receptor, and random skin and bone-marrow biopsies was suggested of primary angiitis of the CNS (PACNS)...

Primary angiitis of the central nervous system (PACNS) is a rare and heterogeneous inflammatory disease of the CNS vasculature with poorly understood pathophysiology. Comprehensive immune-cell phenotyping revealed increased frequencies of leukocytes in the cerebrospinal fluid (CSF) of PACNS patients compared to patients with multiple sclerosis, ischemic stroke, and somatoform disorders (n = 18 per group). Changes in the intrathecal immune-cell profile were heterogeneous in PACNS. While proportions of T-cell subsets remained unaltered, some PACNS patients showed a shift toward NK- or B cells...
