The liver will be divided according to certain areas, in which the S7 segment of the right posterior lobe of the liver in the upper section, S7 segment of the posterior edge of the low-density nodules suggests that the region of the lesions, may be tumors and cysts, the specific diagnosis can not be directly judged, should be carried out pathological biopsy, such as liver perforation to determine the gastric tumors can be surgically resected with adjuvant chemotherapy, cysts, if there is no discomfort can not be dealt with, and regular review can be done, if there is discomfort, surgical resection can be carried out. If there is any discomfort, surgical resection can be performed.
If low-density nodular shadows are found at the posterior edge of the S7 segment of the liver, it is recommended to go to the hospital in time for consultation.
