A male patient in his 40s with a history of nephrolithiasis and found in the desert after 10 days without oral intake was admitted to the hospital for severe dehydration, acute kidney injury and rhabdomyolysis. He had acuteonset loss of consciousness during hospitalisation with new left-sided hemiparesis and hemineglect. After haemorrhage was excluded, prompt thrombolysis was given. He later had chest pain and became hypotensive. An echocardiogram revealed pericardial effusion and dilation of the ascending aorta with suspected dissection. Magnetic resonance angiography of the brain and neck reported bilateral parieto-occipital areas of stroke in a watershed distribution and dissection of the right internal carotid artery. CT angiography showed type A aortic dissection from the ascending aorta extending into the bilateral common iliac arteries. Thrombolysis was reversed and the patient underwent ascending aorta replacement, resuspension of the aortic valve and aortic arch debranching at outside facility with complete recovery.

A pregnant woman in her late 20s with a history of epilepsy since childhood presented with recurrent loss of consciousness and witnessed twitching and involuntary muscle contractions. She had hyperemesis during pregnancy reporting four previous miscarriages attributed to seizures. During evaluation in cardiac telemetry and while suffering from severe nausea, the patient experienced prolonged ventricular asystole resulting in convulsive syncope and was diagnosed with cardioinhibitory malignant vasovagal syncope (CMVS). Initiation of levetiracetam was recommended for 6 months, and after undergoing dual-chamber pacemaker placement, her neurological symptoms resolved despite persistent hyperemesis during the first trimester, leading to a successful vaginal delivery. 4 years later, the patient remains asymptomatic. This case emphasises the importance of conducting a thorough differential diagnosis in patients with atypical seizure presentations, the multidisciplinary approach required to assure optimal outcomes in cardio-obstetric cases and the role of selective pacemaker placement in patients with documented prolonged ventricular asystole associated with CMVS., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.
