Description
Soheil Mirzaei and colleagues describe an incidental beaver tail liver found on chest imaging, calling it an anatomical imposter in the left upper abdomen. Their 2026 case report concerns a rare variant that can mimic spleen-area disease.
A man in his mid-fifties had chest computed tomography for persistent cough and breathlessness. Lower scan sections showed tissue matching liver density beside the spleen. Reconstructed images in other planes showed direct continuity with the left liver lobe, extending as a narrow tongue toward the spleen. No spleen injury, bleeding, fluid, or mass was found. The benign variant needed no treatment. Recognising its continuity with the liver prevents diagnostic confusion.
