A 27‐year‐old human immunodeficiency virus—positive man presented with abdominal pain. Computed tomography of the abdomen revealed large right pleural effusion, pericardial effusion and marked ascites with diffuse intra‐ and extraperitoneal lymphadenopathy. Echocardiography showed severely reduced left ventricular systolic function. After drainage of pleural and pericardial fluid, the patient developed severe hypotension and hypoxic respiratory failure. Extra‐ and intracranial neurovascular sonography demonstrated low carotid artery flow volume and dicrotic pulse waveforms in all vessels insonated bilaterally. This case report demonstrates an atypical dicrotic waveform pattern of transcranial Doppler in advanced ventricular dysfunction with shock.
