Background: The periarteritis nodosa (PAN) is a serious necrotizing vasculitis. Healing is, classically, obtained after a long-term treatment using corticosteroids and immunosuppressive agents.
Purpose: Reporting the case of a NAP or was spontaneous healing without having recourse to any immunosuppressive treatment.
Case Report: We report an observation of a patient aged 27 monitoring for manic-depressive psychosis hospitalized for a fever during the course associated with high blood pressure (hypertension), a weight loss, asthenia and myalgia. Biology was a biological inflammatory syndrome (SIB), a creatinine 115 micromol/l. The survey infectious and immunological balance were negative. The arteriography showed a strongly evocative of the NAP. We have seen no sign of poor prognosis. The recovery was spontaneous after a short period of evolution with an amendment clinical and biological weapons. The patient was put under anti-HTA and reviewed regularly to the consultation.
Conclusion: An analogy is drawn between such developments and already reported in some cases of viral PAN. The actual frequency of self-limitting PAN is unknown. The scarcity of cases reported in the literature may in part be attributed to ignorance.

Fibromuscular Dysplasia (FMD) is a nonatherosclerotic, noninflammatory vascular disorder predominantly affecting women aged 18 to 65 years. This case report highlights a 74-year-old female diagnosed with FMD incidentally during evaluation for deep vein thrombosis (DVT). Imaging revealed significant vascular anomalies, including a giant intracranial carotid aneurysm and a hypoplastic iliac vein with extensive collateral formation.

Purpose: To identify the macular retinal layer thickness changes in polyarteritis nodosa (PAN) patients without pathological findings appearing in color fundus photography (CFP), and to investigate the correlations with disease durations.
Methods: A total of 24 PAN patients who had been for 3 years or more and underwent SD-OCT were recruited from the UK Biobank, with exclusions for diabetes, eye disease, or abnormal CFP findings. Only the right eyes were included, with each PAN patient paired one-to-one with a control matched for age, sex, and ethnicity.

Background: Polyarteritis nodosa (PAN) is a rare and serious form of systemic necrotizing vasculitis that predominantly affects medium and small-sized arteries, with central nervous system involvement being particularly uncommon. Treatment strategies are tailored according to the extent and severity of the disease. While conventional therapy includes glucocorticoids and conventional disease-modifying-rheumatic drugs (cDMARDs), biologic agents may be critical for severe and refractory cases.

Objectives: To describe the clinical profile and compare the long-term outcomes of patients with S-PAN treated with various treatment regimens at our centre in the last 2 decades.
Methods: Data regarding clinical presentation, treatment allocation, relapses and outcomes of patients fulfilling American College of Rheumatology (ACR) 1990 criteria for PAN in the last 2 decades were recorded from electronic medical records. Relapse-free survival and predictors were analysed using KM survival statistics and regression analysis.
