Several pathological entities can present clinically as a soft tissue mass. These tumor- mimicking lesions, also known as pseudo-tumors, can be defined as clinically palpable masses or lesions that have tumor-like appearances on imaging. The advances in cross sectional imaging (ultra-sound, CT and MRI) play an important role in the correct evaluation of soft tissue pseudotumors. That means that in a growing number of situations, we can accurately determine not only the usual information of tumor size and topography, but often the exact nature of the tissue, almost always identifying whether a lesion is aggressive or not. Recognizing soft tissue pseudotumors on imaging may prevent more invasive actions and additional anxiety to the patients. In this pictorial essay we aim to provide a review of common soft tissue conditions which may mimic malignant tumors by classifying them into categories using an anatomical sieve.
