Recurrent syncope as presenting symptom of Burkitt's lymphoma at the carotid bifurcation

Syncope caused by lymphomatous encasement of the internal carotid artery

We present a case of a 77-year-old man who reported 5 months of syncopal episodes. He was found to have diffuse large B-cell lymphoma encasing the left internal carotid artery but not impeding blood flow. The syncopal episodes resolved after his first cycle of chemotherapy. Recurrent syncope in non-cardiac lymphomas and other head and neck masses is exceedingly rare and may be due to reflex syncope prompted by carotid baroreceptor activation. There are 11 previously described cases of recurrent syncope associated with non-cardiac lymphoma. In all cases, lymphadenopathy abutting the carotid artery was present and the syncopal episodes resolved with treatment. Our case illustrates that malignancy should be considered in patients with unexplained recurrent syncope.

An Unusual Initial Presentation of Diffuse Large B-Cell Lymphoma as Recurrent Syncope

We describe a rare presentation of diffuse large B-cell Lymphoma (DLBCL) with recurrent episodes of syncope. During the workup for syncope, the patient was incidentally found to have an extensive mass in the left thorax, which was later diagnosed as stage 2 bulky disease DLBCL. This is the rare case of lymphoma presenting as recurrent syncope without cardiac involvement. The patient did not have any further episodes of syncope after her successful treatment of DLBCL.

Burkitt lymphoma as a cause of carotidynia: imaging features. A case report

We describe a patient with Burkitt lymphoma who developed carotidynia. MRI showed thickening of the walls of both common carotid arteries and PET CT showed increased radiotracer uptake in the same regions. MRI was essential in establishing the diagnosis of this rare clinical presentation.
