Objective: As one of the diagnostic criteria for giant cell arteritis affecting the temporal arteries (temporal arteritis) is still biopsy-proven vasculitis of the affected artery, the aim of our study was to evaluate the value of a non-invasive procedure, 2-(18)F-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (F-18-FDG-PET), in the diagnosis of Horton's disease.

Methods: During a period of 10 months, 22 consecutive patients with the clinical diagnosis of giant cell arteritis and a positive hypoechogenic halo in duplex sonography were re-examined with F-18-FDG-PET. Six patients had giant cell arteritis involving both the large arteries and the temporal arteries; five patients showed giant cell arteritis only in the large arteries without concomitant involvement of the temporal arteries, and the remaining 11 patients showed only involvement of the temporal arteries.

Scintigraphy with 67Ga-citrate indicated the transition of an orbital pseudotumor into a lymphoma by a distinct increase in 67Ga avidity. The patient initially presented with a pseudotumor in the right orbit that was verified by CT and MRI. It was caused by a chronic reactive lymphocytic inflammation extending from the lacrimal gland.

Tracheal stenosis due to infiltrative nonresectable thyroid cancer causes severe reduction in life quality. Palliative therapy, apart from tracheostomy is--up to now--intraluminal and/or external radiation. Good tumor control is achieved by local hyperthermia.

Unlabelled: This prospective study evaluated somatostatin receptor-specific scintigraphy as a clinical tool for routine detection of malignant lymphoma.

Methods: Forty-one consecutive patients were examined using 111In-DTPA-D-Phe-1-octreotide. Thirty-four patients had diagnoses of Hodgkin's disease (n = 11) or non-Hodgkin's lymphoma (n = 23) previously verified and staged by hematology, histology and imaging methods (CT, chest x-ray and abdominal ultrasonography).
