ABSTRACT
Diffuse alveolar hemorrhage (DAH) is a rare, acute, and life-threatening condition that in most cases is associated with pulmonary-renal syndromes, connective tissue disorders, infections, and drugs. We report a case of a 45-year-old male who developed a diffuse pulmonary hemorrhage after taking 500 mg of acetylsalicylic acid for a month in the context of acute lower back pain. The prolonged use of this acetylsalicylic acid dose led to an increased risk of bleeding. This report describes a rare bleeding site that clinicians should be aware of when managing patients who were exposed to prolonged high dose acetylsalicylic acid.
ABSTRACT
Pulmonary arteriovenous malformation (PAVM) is well recognised as a cause of paradoxical brain embolism. The authors report the case of an older woman with a medical history of arterial hypertension who was found unconscious and was discovered to have pulmonary thromboembolism and ischaemic stroke related to a PAVM.

Type A aortic dissection is a surgical emergency occurring when an intimal tear in the aorta creates a false lumen in the ascending aorta. The authors report the case of an older woman with a medical history of arterial hypertension, atrial fibrillation, dyslipidemia, heart failure, and osteoarticular spinal pathology, presenting with sudden and persistent retrosternal pain, who was initially misdiagnosed with a lower airway infection and was discovered to have an acute type A aortic dissection. The authors intend to draw attention to medical errors and emphasize the importance of early diagnosis in pathology with a potentially fatal prognosis.
