A case of ANCA associated vasculitis in a patient presenting with chest pain.
2020
Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) is a group of multisystem autoimmune small vessel diseases. We report here a case of a 68-year-old woman who initially presented with 29-day history of chest pain, malaise and anorexia. Cardiac problems were ruled out and she was considered to have pneumonia. Her symptoms persisted and blood tests showed renal impairment and evidence of an inflammatory response. A kidney biopsy, chest computed tomography (CT) scan and ANCA testing confirmed a diagnosis of AAV renal injury. She was treated with glucocorticoids and cyclophosphamide (CTX) for six months at which time her kidney function had improved and she avoided the need for dialysis. This case study illustrates that the clinical manifestations of AVV are complex, varied, and prone to misdiagnosis.
