From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. Very rare cases of intramuscular ganglion cysts in the gastrocnemius muscle of the calf have been reported.
What exactly is a âbomb cycloneâ? A bomb cyclone is a low-pressure system that intensifies very rapidlyâyou have to have a fall in pressure of at least 24 millibars in 24 hours to qualify as a âbomb cyclone,â or âbombogenesis,â event.
Bombogenesis is cyclogenesis taken to the extreme. Bombogenesis is defined as a mid-latitude cyclone that drops in surface barometric pressure by 24 or more millibars in a 24-hour period. The height contours pack around the center of rotation and the number of height contours increases rapidly in the developing stages.
