Substantial intraoperative bleeding during surgical removal of carotid body tumor may be a major problem in the management of these highly vascularized tumors. Traditional preoperative embolization via a transarterial access has proved effective but is often limited by complex vascular anatomy and small feeding vessels that is difficult to catheterize. We report two cases of carotid body tumor ...

A 33-year-old woman was admitted to our hospital with a slow-growing mass in the left side of her neck. The mass was found to be a huge (73 × 56 × 54 mm) carotid body paraganglioma. Another 21 mm-size tumor was incidentally detected at the right carotid bifurcation. She had hoarseness and Horner's syndrome of her left side. Both tumors were surgically removed. There were no cerebrovascular comp...

IT IS AXIOMATIC that the respiratory chemoreceptors sense and respond to changes in the composition of their immediate microenvironment.78 In humans, the ventilatory response to a step change in end-tidal CO2 yields a fast (τ ∼10 s) and a slow component τ ∼120 s).12,40 Two sets of chemoreceptors are thought to elicit these two components: the peripheral chemoreceptors, causing the fast componen...

Carotid body tumor (paraganglioma) is a rare tumor which presents as a mass in the lateral part of the neck. It is typically a slow-growing and nonsymptomatic mass at the beginning. Fever is not an usual symptom of this tumor. Here, we report a 78- year-old woman presenting with this tumor as a cause of fever of unknown origin.

Carotid body tumor is a rare neoplasm, occasionally familial in occurence, is difficult to establish its malignancy histopathologically. In this paper, we report two cases seen in the same family. As far as our survey concerned present report on the familial incidence is the second in Japan. Case 1: I. K., 13 years old girl. She visited a hospital with complaints of the neck mass and low grade ...

OBJECTIVE To summarize the experience in the diagnosis and treatment of carotid body tumor (CBT). MATERIALS AND METHODS CBT in 18 cases was confirmed by digital subtraction angiography (DSA). Resection of the tumor under the carotid adventitial plane was performed in 10 cases, the tumor with the external carotid artery in five cases, and the tumor with the internal and external arteries at th...
