We describe a case of a proximal anterior leg mass causing weak great toe dorsiflexion. The lesion was demonstrated on MR imaging as a multilocular cystic lesion within the extensor digitorum longus muscle that was connected to the proximal tibio-fibular joint by a pedicle. Fluid extravasation was present that extended inferiorly from the lesion along the fascial planes into the distal anterior lower leg. At surgery, the lesion was found to be compressing the deep peroneal nerve. The final pathologic diagnosis was peroneal ganglion cyst.
IntroductionIntravenous drug abuse unfortunately remains an extremely common problem worldwide, accounting for innumerable medical issues ranging from the transmission of human immunodeficiency virus (HIV) and other blood-borne diseases to skin necrosis to vasculitis to death [1]. We present a case of intra-arterial injection of alprazolam into the right femoral artery resulting in microembolization, acute ischemia and rhabdomyolysis of the thigh, as documented by magnetic resonance (MR) and laboratory findings.
IntroductionTrapezius muscle injuries often occur in conjunction with high-grade acromioclavicular joint injuries [1], but to our knowledge, isolated trapezius injuries have not been described in the literature. We present a case of isolated trapezius strain in a spastic patient with multiple sclerosis documented with magnetic resonance imaging (MRI).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
