Brachial plexopathy includes a wide range of disorders affecting the brachial plexus, with etiologies such as trauma, neoplasia, inflammation, and positional compression. Positional brachial plexopathy is an uncommon but well-recognized complication of prolonged immobilization, particularly in patients with altered consciousness. We report the case of a 25-year-old patient admitted for impaired consciousness secondary to cannabis intoxication, complicated by prolonged immobilization with compression of the right upper limb. The patient developed a right flaccid monoparesis. Magnetic Resonance Imaging (MRI) and ultrasound (US) of the brachial plexus demonstrated inflammatory changes consistent with right positional brachial plexopathy. This case emphasizes the complementary role of MRI and ultrasound in the assessment of non-traumatic brachial plexus injuries [1,2].
