Abstract:
Uterine adenomyosis usually manifests as diffuse disease involving the myometrium and the endometrial-myometrial junction, but it may also manifest as a focal lesion. It is usually only a few millimeters in diameter but may sometimes be larger. We report the case of a 32-year-old woman with a large isolated mass in the uterine wall. Transvaginal sonography demonstrated the cystic nature of the mass and its characteristic hemorrhagic pattern, whereas CT confirmed its uterine origin. The patient underwent laparoscopic resection of the mass, and pathologic examinations led to the diagnosis of adenomyosis.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
