inferolateral

Inferolateral is an anatomical directional term used to describe a location that is both inferior (toward the feet) and lateral (away from the midline) relative to a reference point in the standard anatomical position. It is commonly applied to describe parts of the body that lie toward the lower outer aspect of a structure or region, such as the inferolateral wall of the left ventricle or the inferolateral surface of an organ.

Etymology and usage: The word combines Latin inferus (lower) and latus (side). In medical and anatomical texts, inferolateral is used alongside other directional terms like inferomedial, superolateral, and superomedial to refine the description of a structure’s location. Descriptions may pertain to organs, bones, vessels, or soft tissues and are routinely encountered in clinical, radiological, and surgical settings.

Examples: The inferolateral wall of the left ventricle is a common descriptor in cardiology, particularly in discussions of regional function or infarction risk. In the orbit, the inferolateral wall refers to the lower outer portion formed by surrounding bones. In radiology, reports may describe lesions or features as being in the inferolateral quadrant of an organ or region.

Caution: The interpretation of inferolateral depends on the reference frame, typically the patient’s anatomical position. Therefore, precise localization should be cross-referenced with accompanying images or descriptions to avoid ambiguity.
