DIAGNOSIS OF A GLOMUS-CAROTICUM TUMOR-REC URRENCE BY SOMATOSTATIN RECEPTOR SCINTIGRAPHY

Glomus caroticum tumours belong to the non chromaffine paragangliomas. As the incidence is very poor with 1% in the collective of a vascular -surgery department, the correct diagnosis is preoperatively only foun d in 10-20% of the cases. The early detection of primary- or recurrenc e-tumour is important for the surgical proceedings. With advanced tumo ur-stage, i.e. with involvement of the carotid artery in the tumour-pr ocess, the perioperative mortality increases. Furthermore nerve lesion s following surgical tumour-resection as a complication are more frequ ent. This case-report point out the importance of the somatostatin-rec eptor-scintigraphy in the differentiation of glomus caroticum tumour-r ecurrence and postoperative scar. in our patient the suspicion of tumo ur-recurrence came up already 2 years ago, but could not be verified b y MRT and angiography.
