Flauwvallen door een tumor in de hals

An 86-year-old woman was admitted with progressive complaints of dizziness and the sensation of losing consciousness several times a day; this had led her to fall down on a few occasions. The patient had experienced these symptoms for a month prior to admission. Two weeks before admission her family had noticed a swelling on the left side of her neck. During admission, bradycardia and subsequently asystole occurred while she was eating or when turning her head to the left, followed by a slow junctional escape rhythm. A CT scan of the head and neck region revealed a large tumour in the left parapharyngeal space entrapping the left carotid artery. Histology disclosed a low-grade malignant non-Hodgkin lymphoma, sensitive to radiotherapy. The patient received a pacemaker and treatment of the lymphoma was uneventful. The symptomatic sinus bradycardia and asystole were caused by intermittent carotid massage by the lymphoma.
