Unilateral hypertrophy of the tensor fasciae latae (TFL) is an uncommon radiologic finding that may present as a palpable soft tissue mass in the thigh. Accurate radiologic diagnosis can circumvent unnecessary biopsy for this benign finding. We report two cases of unilateral hypertrophy of tensor fasciae latae muscles, both of which presented as a proximal thigh mass. We provide examples of sonographic, computed tomography (CT), and magnetic resonance imaging (MRI) features.
