Core Tip
Core tip: We retrospectively analysed 79 upper limb computer tomography angiographys for extravascular incidental findings (EVIFs). These were grouped into 3 categories based on clinical significance, category A (immediate), category B (indeterminate) and category C (no clinical significance). A total of 153 EVIFs were reported in 52 patients. Of these 13 EVIFs (8.4%) were Category A, 50 EVIFs (32.3%) were Category B, while 91 EVIFs (59.5%) were Category C. One index case of malignancy (1.3%) and four cases of new disseminated metastatic disease (5.4%) were identified. This highlights the importance for both the reporting radiologist and the referring physician to recognize the frequency of EVIFs.
