An 11-year-old girl with leukemia undergoing chemotherapy developed a severe fungal infection called mucormycosis caused by Lichtheimia ramosa. The infection spread rapidly from her sinuses to her eyes and brain, causing multiple blood clots in brain arteries and a massive stroke within just five days. Despite emergency surgery to remove the clots, the infection had progressed too far and the patient sadly did not survive, highlighting how dangerous this fungal infection can be in children with weakened immune systems.
