Core Tip

Core tip: Psoas muscle metastasis, though unusual, forms the commonest site of skeletal muscle involvement in cervical carcinoma. The present communication describes the comparative diagnostic features of this relatively unusual but important entity on newer non-invasive molecular imaging modalities such as fluorodeoxyglucose-positron emission tomography/computed tomography (CT) and diffusion-weighted imaging of magnetic resonance imaging (MRI) as well as the conventional imaging modalities (e.g., ultrasound, CT and MRI). Currently, there is a lack of characteristic diagnostic imaging features on conventional imaging modalities which have been nonspecific in this domain, and the differential diagnosis includes sarcoma, hematoma, and abscess, thus the newer molecular imaging approaches need critical exploration and comparison.
