Plantar pain is a common problem endured by most adults at some point in their life that may result in considerable disability. Plantar fibromatosis is a locally invasive neoplasm, with the development of fibrous nodules on the plantar aspect of the feet, which can remain asymptomatic for years. (18)F-Fluorodeoxyglucose ((18)F-FDG) PET/CT has been more prevalent as the imaging modality of choice for cancer patients, but the imaged field of view is often from the base of the skull to the upper thighs. ⋯ One such finding is the presence of (18)F-FDG-avid plantar nodules. This review is intended to help clinicians become aware of these potential false-positive nodules that can affect a patient's staging and management.

Extramammary Paget's disease (EMPD) is rare, and limited data have been reported on the utilization of fluorine-18 fluorodeoxyglucose PET/computed tomography ((18)F-FDG PET/CT) in this disease. The aim of this study is to evaluate the role of (18)F-FDG PET/CT in the diagnosis and staging of EMPD. ⋯ (18)F-FDG PET/CT diagnosis of primary lesions in EMPD is mainly dependent on the thickness of the lesions, whereas it is more sensitive for the diagnosis of metastases.

The aim of the study was to assess the potential interest of combining a low-dose computed tomography (ldCT) to ventilation/perfusion (V/Q) single-photon emission computed tomography (SPECT) for the diagnosis of pulmonary embolism (PE). We addressed three main questions: Could ldCT be used in substitution to ventilation SPECT? Could ldCT improve the diagnostic performance of V/Q SPECT? Could ldCT provide alternative diagnoses to PE? ⋯ For PE diagnosis with lung SPECT, the use of ldCT in substitution to ventilation SPECT is associated with a high risk of overdiagnosis. The diagnostic value of ldCT in addition to V/Q SPECT remains unclear. Further studies are needed to determine its potential role in PE diagnosis.
