Are carotid body tumours malignant? Case 13 Case All authors read and approved the final manuscript. Case presentation We present a year-old female patient with a glomus tumor treated with positron emission tomography computed tomography planning and 3D conformal radiotherapy, and the patient has remained free of disease progression 2 years after.

This article is available from: Glomus tumor during carottideo. Salt and pepper appearance is seen on both T1 and T2 weighted sequences; the salt representing blood products from hemorrhage or slow flow and the pepper representing flow voids due to high vascularity. Clinical presentation is usually with a slow growing rounded neck mass.

The treatment options are surgery, RT and watchful waiting. Case 5 Case 5. Arteriographic examination in which the rich tumoral vascularization can be seen, in addition to absence of contrast filling the external carotid. NMJ Analysis and interpretation: Because of the insidious onset of symptoms, these tumors often go unnoticed, and delay in diagnosis is frequent.

Glomud patient underwent imaging exams during the preoperative period.

Notes Consent Written informed consent was obtained from the patient for publication of this case report and accompanying images.

Tumours may be bilateral, and other tumours such as carotid body tumours may coexist. Bulging mass with an irregular, nodular hemorrhagic cut surface Superficial lesions typically. Carotid body tumour, also known as a chemodectoma or carotid body paraganglioma, is a highly vascular glomus tumour that arises from the paraganglion cells.


Complications are however not uncommon due to the large number of sensitive structures in the region and include:. Case 6 Case 6. The characteristic appearance of GT in MRI is well-defined hypointense mass with equal signal intensity to adjacent muscle on T1-weighted scans. Radiotherapy has become a primary treatment modality for GT in patients with unresectable symptomatic tumors, and bilateral tumors, in which, a good local control and reasonable tumor shrinkage was achieved in our case.

Gaylis H, Mieny CJ. Trends in neurovascular complications of surgical management for carotid body and cervical paragangliomas: Additionally a number of patterns of cranial nerve palsies have been described due to involvement of the nerves at the jugular foramen. Two glands were removed for histopathological analysis. Images hosted on PathOut server: Case 3 Case 3.

According to Shamblin et al.

Glomus tumors respond to RT slowly. On systemic evaluation only hypertension diagnosed for 3 years which was under control with medications.

The initial diagnosis is usually non-tender neck mass, in case of rapid growth or increase in size, because of compression to the surrounding structures, pain, hoarseness, disphagia may develop. The patient recovered well during the postoperative period, with no complications, and was discharged on the second postoperative day.
