PURPOSE: To identify and characterize mimickers of solid tumors presented to a multidisciplinary rapid cancer diagnosis unit
MATERIAL & METHODS: We retrospectively reviewed 153 consecutive imaging studies presented to the recently founded rapid cancer diagnosis unit at our center, and compared imaging to pathological results. We identified space occupying lesions, which were initially interpreted as solid tumors, but were pathologically rebutted. Their features were analyzed.
RESULTS: Out of 153 studies reviewed, 131 were initially suspected as solid tumors, 22 suspected as hematological malignancies. Of those, 8 (5%) had a different pathological diagnosis (a single case of abscess, pseudotumor, and a bleeding FNH, 2 cases of multiple myeloma, and 3 cases of extranodal lymphoma).
CONCLUSION: In the setting of cancer diagnosis, the reader should be aware of the features of space occupying lesions mimicking solid tumors.
