Multiple nodular soft tissue density shadows in the abdominal cavity is an imaging test, which is considered to be possibly related to bacterial infection, tuberculosis infection, malignant tumors and so on. 1. Bacterial infection: when intra-abdominal infection occurs, such as the presence of mesenteric lymph node inflammation, local reactive hyperplasia can occur, and multiple nodular soft tissue density shadows can be observed on imaging. 2. Tuberculosis infection: when there are tuberculosis lesions in the abdominal cavity, it can also lead to abdominal masses in the form of nodules, and the patient can have symptoms of fatigue, low-grade fever, night sweats (sweating abnormally after going to sleep, and sweating stops after waking up), anemia, and abdominal pain, which need to be treated with anti-tuberculosis drugs as soon as possible. 3. Malignant tumors: At this time, it is also necessary to rule out the existence of malignant tumors. Malignant tumors often metastasize to the abdominal cavity through lymphatic transfer, and the abdominal cavity is also a good site for lymphoma. Therefore, multiple nodular soft tissue density shadows found in the abdominal cavity need to be further examined in terms of tumor. If multiple nodular density shadows are found in the abdominal cavity, it is recommended to consult the general surgery department or gastroenterology department of regular hospitals to improve the examination and make a clear diagnosis.
