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.
Monarch flight is float-like in comparison, with its characteristic flap, flap, glide pattern. Timing Viceroys do not migrate. They overwinter as 1st or 2nd instar larvae, rolled up in a leaf of their host plant (willow or poplar). In the spring, the larvae need about 15 days to complete the life cycle and become a butterfly. They must develop through the remaining instars (approximately 5 days) and the chrysalis stage (at least 10 days).
