Carotid body tumor as a cause of stroke

Carotid body tumor (CBT) is the most common form of paraganglioma of the head and neck region (1). Paraganglioma grow slowly and rarely metastasize, can be familial or sporadic, functional and non- functional. CBT have been source of transient ischemic attacks in 5-15% of the 600 or more reported cases (2). A 78-year old woman was admitted to hospital due to sudden onset of mild to moderate left hemiparesis. MRI of the brain confirmed acute ischemic lesion right periventriculary. Ultrasound of the carotid and vertebral arteries showed highly vascular tumor mass (proportions of 11.8x8.5 mm) speculative on CBT on the bifurcation of right common carotid artery, which is confirmed with MSCT angiography and MRI of neck. The patient was examined by surgeon who has indicated elective surgery of CBT. Surgically removed tumor was approximately 2x2 cm in area of right carotid bifurcation (gradus II according to Shambling classification) and patohistological analysis confirmed CBT. The surgical procedure and postoperative period have passed without complications. The hormonal activity was excluded. Connection between CBT and ischemic attack is not that often reported in literature but for sure can be taken as one of the risk factors for morbidity in patients who are diagnosed with it (3). In each patient with stroke, ultrasound of carotid and vertebral arteries should be part of routine investigations to exclude the existence of TKT, which sometimes requires greater experience in performing tests.
