More than 50 years after being bitten by a venomous snake, a woman developed a large mass in her lower leg, according to a new report of her case.
The 66-year-old woman in Thailand had been bitten by a Malayan pit viper, a venomous snake native to Southeast Asia, when she was 14.
The painless mass had become noticeable 10 years earlier, and on an X-ray it looked like an enlarged cavity wrapped in a tough, calcified membrane, resembling an eggshell. It ultimately grew so large that it broke through the woman’s skin. Doctors surgically removed the mass, and the wound completely healed by one month after the surgery, they wrote in their report, published June 16 in the Journal of Medical Case Reports.
Such masses have rarely been reported following a snakebite, but they have been seen following other types of traumatic injury to muscles, according to the report’s authors, who are researchers at the Prince of Songkla University in Thailand.
