Retropharyngeal abscess with cervical discitis and vertebral osteomyelitis caused by Escherichia coli in a patient with liver cirrhosis.

We describe the case of a 67-year-old male with liver cirrhosis who presented with fever and neck pain. Magnetic resonance imaging of the spine detected cervical vertebral osteomyelitis, and enhanced CT of the neck and spine revealed retropharyngeal abscess. The patient was treated with empirical antimicrobial therapy and surgical drainage due to significant airway involvement.

We experienced a case of Kounis syndrome with cardiopulmonary arrest and severe coronary spasm. A 70-year-old man with cardiac pacemaker and chronic dialysis was treated for angina pectoris of the right coronary artery. After diagnostic coronary angiography of the right coronary artery, optical coherence tomography was performed with contrast medium and low-molecular-weight dextran.
