In this report, we present a case of monoarticular hip involvement in pseudogout presenting as soft tissue abscess on MRI. Monoarticular hip involvement in pseudogout is a rare entity and up to our knowledge this is the first case mimicking soft tissue abscess.
Monarch butterflies are known for their long annual migration. In North America, they make large migrations towards the south starting in August until the first frost. A migration towards the north takes place in the spring. No single individual makes the whole round trip.
Among the two species of Monarch butterflies, the one in North America differs from the one you will find in South America, but the Caribbean is home to both species. You can also see them in Australia, New Zealand, and several Islands lying between Australia and Tahiti, in parts of Europe and in Hawaii.
