Morphologic Variation of Liver Associated With Hourglass Stomach: Case Report and Literature Review.

Ectopic liver tissue is a rare developmental abnormality, and its association with hourglass constriction of the stomach is undocumented to date. This case report describes the discovery of morphologic variations in the liver of an adult female cadaver during routine dissection. The variations include a small, pedunculated, club-shaped accessory lobe covered by a glistening fibrous capsule connecting it to the gallbladder wall, with vessels radiating into the lobe. Two additional lobes were present, one attached to the right upper margin of the caudate lobe, overlapping the inferior vena cava, and another near the quadrate lobe. The right lobe had an abnormal shape with multiple incomplete fissures and furrows. The left lobe was hypoplastic with an elongated end, resembling a lingular process. Further dissection revealed a prominent fibrous band on the posterior surface of the stomach, which continued anteriorly, giving it an hourglass appearance. Knowledge of such variations helps surgeons and radiologists rule out related abnormalities.
