Abstract:
Mycotic aneurysms can pose a diagnostic dilemma due to their variable presentations. We present a case of a 93-year-old man initially presenting with fevers, intermittent chest pain and normocytic anaemia refractory to repeated blood transfusions. He received intravenous ceftriaxone as Escherichia coli grew in his blood cultures. His chest X-ray showed a widened mediastinum. A subsequent CT of the chest discovered a mycotic aneurysm at the descending thoracic aorta. He had a good outcome and was thriving after 1 year post endovascular repair.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
