During ultrasound, the doctor assesses not only the structure of the organ, but also its size. This is important because enlargement of the organ may be associated with infectious diseases, blood pathologies, liver diseases, circulatory disorders, or other conditions.
The approximate normal spleen size in adults:
| Indicator | Approximate value |
| Length | up to 11–12 cm |
| Width | up to 6–8 cm |
| Thickness | up to 4–5 cm |
These indicators are consistent with the data of the study by Rosenberg H.K. et al. (USA), in which it was established that in most patients the length of the spleen does not exceed 11 cm, the width — 7 cm, and the thickness — 5 cm.
These values are approximate. In different patients, sizes may differ depending on height, body weight, age, anatomical features, and general health condition. Therefore, the doctor assesses not only the numbers, but also the structure of the organ, its contours, tissue homogeneity, and the presence of additional changes.
Doctors of Oxford Medical explain: if the organ is enlarged, this does not automatically mean the presence of a severe disease. Such a change may be temporary or associated with different causes, therefore the ultrasound result should be assessed comprehensively with blood tests and the general clinical picture.
