RESUMO
We describe a patient with CT-proven ischemic infarction of the left middle cerebral artery (MCA) territory. The emergency CT, on admission, was suggestive of intracranial internal carotid artery dissection by demonstrating gaseous gap defects in the arterial wall and a subsequent thromboembolic process in the MCA. To our knowledge, there is no previous report regarding radiologically detected gas within the vessel wall or lumen secondary to dissection. We discuss this uncommon radiologic sign and its possible pathogenesis with a review of the literature.

Metatarsophalangealjoint injuries of the great toe are receiving increasing attention in athletes. Significant disability and long-term morbidity can result from these focal injuries. The entity known as turf-toe is widely recognized. Rupture of the medial collateral ligament of the first metatarsophalangeal joint is less common. A case of traumatic rupture of the medial collateral ligament in the great toe of a soccer player, which progressed to hallux valgus deformity, is presented.
