A 21-year-old female with a known history of homozygous Sickle Cell Anemia (HbSS) presents to the emergency department complaining of mild, chronic left upper quadrant abdominal discomfort. She denies acute fever, severe pain, or recent trauma. She has a history of multiple vaso-occlusive crises in childhood. Ultrasound Findings: Splenic bed: No splenic tissue is visualized in the normal anatomical position.
