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.
To avoid the cold, and the scarcity of food when flowers stop blooming and insects stop flying, they go south. Some adult males start migrating south as early as mid-July, but the peak of southward migration for this species is late August and early September.
