Abstract
Benign pseudocyst of adrenal gland (Ag) during pregnancy can turn into complication of pregnancy when it grows large and ruptures. There are very few cases reported as far as the size and the complex echo pattern seen in the case reported here. We assessed the usefulness of routine ultrasonography for the right upper quadrant (RUQ) and back pain symptoms during pregnancy. Cat scan (CT) was also useful in making the surgical treatment diagnosis in this case. Ultrasonography is a readily available imaging modality that is useful in guiding the correct treatment, localizing, and identifying the mass and the echo pattern before turning to CT scan or any other imaging modality. In this case, although the size and the complex echo pattern of the mass did not make it difficult to diagnose, careful scanning made the correct diagnosis.
