Delayed presentation of a pneumatic nail gun injury to the right ventricle without circulatory compromise.

Delayed presentation of penetrating cardiac injuries is exceedingly rare due to the observed near 100% pre-hospital mortality. We describe a case of a patient who presented for evaluation nearly 24 h after sustaining a self-inflicted pneumatic nail gun injury to the right ventricular outflow tract. Remarkably, the patient had no evidence of hemodynamic compromise. This case highlights the importance of maintaining a high index of suspicion for cardiac injury with penetrating trauma to the cardiac box regardless of presenting signs and symptoms, and the value of adhering to advanced trauma life support principles.

An atypical case of acute posterior multifocal placoid pigment epitheliopathy with recurrent strokes.

PURPOSE: To report an atypical case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) with central nervous system (CNS) vasculitis and recurrent strokes. OBSERVATIONS: A 57 year-old female presented with APMPPE after a febrile illness and rash. She developed an acute infarct on magnetic resonance imaging. Computed tomography angiography of the cerebral vasculature was normal. Cerebrospinal fluid (CSF) analysis and an extensive serum lab workup were also unremarkable. She was treated with high-dose corticosteroids and eventually transitioned to methotrexate. A month after being on treatment she developed a second stroke. A cerebral angiogram was obtained and did not show evidence of CNS vasculitis. The methotrexate was eventually stopped and the prednisone was tapered. Approximately 3 months later she developed a third stroke and worsening APMPPE-associated maculopathy in both eyes. She was eventually started on oral cyclophosphamide. CONCLUSIONS & IMPORTANCE: Although rare, CNS vasculitis is a known complication of APMPPE. This case is atypical given the development of multiple recurrent strokes, lack of inflammatory evidence on CSF analysis, and normal imaging of the cerebral vasculature. This report highlights the need for a high level of clinical suspicion for CNS vasculitis with APMPPE despite noncontributory cerebral angiographic imaging and normal CSF analysis.
