Liver of an Obese Male

Description

Positioned in the right upper quadrant beneath the costal margin, the liver (hepar, jecur) appears as a smooth, arched organ with its diaphragmatic surface conforming to the undersurface of the right hemidiaphragm. A standing male body habitus frames the organ in situ, with the hepatic dome lying superior and lateral, and the inferior margin tapering anteroinferiorly toward the right hypochondrium and epigastrium. Medially, the liver’s bulk approaches the midline where the left lobe would extend across the epigastrium, while the right lobe remains dominant in volume in this externalized, partial cutaway presentation. Surface anatomy matters. Obesity changes how clinicians encounter the liver, not just its pathology. Increased adiposity can obscure palpable landmarks and shift ultrasound windows, while nonalcoholic fatty liver disease and steatohepatitis enlarge the organ and contribute to a rounded inferior edge that may be detected during physical exam or noted on imaging. This external body context also aligns with procedural planning, including right upper quadrant ultrasound, percutaneous biopsy trajectories, and laparoscopic port placement where the costal margin, xiphoid region, and expected hepatic position guide safe access. Suitable for gross anatomy and surface anatomy teaching, this artwork also fits hepatology and bariatric medicine materials that explain hepatomegaly, fatty infiltration, and altered examination findings in the obese male. Publishers can pair it with patient education on liver location and common metabolic liver disease, or with radiology primers on choosing sonographic intercostal windows.
