Úvod: Burzy jsou tíhové váčky vystlané synoviální vrstvou buněk a obsahují tekutinu podobnou kloubní synovii. Jejich účelem je snižovat mechanické namáhaní (tření) v místech kontaktu šlach s kostí, kloubním pouzdrem anebo vazem. Vlivem různých příčin se může burza zanítit a způsobovat pacientovi obtíže. Burzitidu je možné diagnostikovat zavedením metodiky časného SPECT/CT při vyšetření skeletu. Kazuistiky: Uvádím zde tři pacienty, dva přišli s bolestí kolenních kloubů trvající několik měsíců a jeden s bolestí v oblasti bederní páteře, u kterých byla diagnostikovaná burzitis na třífázové scintigrafii skeletu. Závěr: Dle BOSS klasifikace patří všechny burzitidy do tvz. skupiny C (neboli extraoseální). Tyto patologie na scintigrafii skeletu odhalí pouze provedení SPECT/CT ve fázi blood poolu.
Introduction: Bursae are weight-bearing sacs lined with a synovial layer of cells and contain a fluid similar to joint synovium. Their purpose is to reduce mechanical stress (friction) in the points of contact of tendons with bone, joint capsule or ligament. Due to various reasons, the bursa can become inflamed and cause difficulties for the patient. It is possible to diagnose bursitis by introducing early SPECT/CT methodology during the examination of the skeleton. Case reports: Three patients are presented here, two with pain in the knee joints lasting several months and one with pain in the area of the lumbar spine, who were diagnosed with bursitis on three-phase skeletal scintigraphy. Conclusion: According to the BOSS classification, all bursitis belongs to what is known as group C (or extraosseous). These pathologies on bone scintigraphy can only be detected by performing SPECT/CT in the blood pool phase.

AIM: Polymyalgia rheumatica (PMR) is a disease presenting with pain and stiffness, mainly in shoulders, hip joints and neck. Laboratory markers of inflammation may bolster diagnosis. PMR afflicts patients over 50 years old, predominantly women, and may also accompany giant cell arteritis. PATIENTS AND METHODS: 67 patients, who fullfiled Healey´s criteria for PMR in the period between 2004 and 2013 and had positive FDG PET (PET/CT) findings were retrospectively evaluated. FDG uptake was assessed in large arteries, proximal joints (shoulders, hips and sternoclavicular joints), in extraarticular synovial structures (interspinous, ischiogluteal and praepubic bursae). RESULTS: Articular/periarticular involvement (A) was detected in 59/67 (88.1%) patients and extrarticular synovial involvement (E) in 51/67 (76.1%) patients either individually or in combinations. Vascular involvement (V) was detected in 27/67 (40.3%) patients only in combination with articular (A) and/or extraarticular synovial (E) involvement. These combinations were: A+E involvement in 30/67 (44.8%) patients, A+V involvement in 8/67 (11.9%) patients, E+V involvement in 6/67 (9%) patients and A+E+V in 13/67 (19.4%) patients. CONCLUSIONS: PMR presents by articular/periarticular synovitis, extraarticular synovitis and can be accompanied by giant cell arteritis. All types of involvement have their distinct FDG PET (PET/CT) finding, which can be seen either individually or in any of their 4 combinations. FDG PET (PET/CT) examination seems to be an advantageous one-step examination for detecting different variants of PMR, for assessing extent and severity and also for excluding occult malignancy.
