With the continuous improvement of living standards, people pay more and more attention to the management of their own health. The concept of regular medical checkups, timely detection of abnormal signals from the body, early diagnosis, early intervention and early treatment has gradually gained popularity. But it is because of regular medical checkups, but some friends have brought a lot of fright. The report results clearly stated “consider hepatic hemangioma, please combine with clinical diagnosis”, without any clear symptoms, how to get “tumor”? How could I have gotten a “tumor”? So I panicked and went to the doctor with the results, and after some consultation and treatment, I finally breathed a sigh of relief. Today, we will talk about the common benign occupying lesions of the liver —— are not easy to find, but should not be ignored those “little things”. Hepatic hemangioma is the most common benign mesenchymal cell tumor of the liver, with tumor sizes ranging from less than 1 cm to more than 20 cm, and when it exceeds 4 cm, it is called a giant hemangioma. This hemangioma is considered a benign congenital misshapen tumor. A significant number of patients with hemangiomas have no typical clinical symptoms, while some patients have “atypical” symptoms such as abdominal discomfort and loss of appetite. Ultrasound alone can confirm the diagnosis in 80% of lesions smaller than 6 cm, while larger hemangiomas, which are more heterogeneous, require abdominal enhancement CT or abdominal enhancement MRI. Once a hepatic hemangioma is diagnosed, you do not need to panic and seek prompt medical attention. For hepatic hemangioma, regular checkups are usually all that is needed and no treatment is required. However, if the patient has severe symptoms, or if the hemangioma exceeds 8 cm, or if it increases significantly in a short period of time, or if the hemangioma does not reach a size that requires treatment but is in a special location, such as near a large blood vessel, then hepatic hemangioma resection may be considered. For hepatic hemangiomas that are superficially located, such as in the left outer lobe of the liver, minimally invasive surgery is preferred, such as laparoscopic resection of hepatic hemangiomas. Second, focal nodular hyperplasia (FNH) Focal nodular hyperplasia is second only to hemangioma in the incidence of the most common benign occupying lesions in the liver. In fact, FNH is a disorganized, tumor-like nodular lesion of normal hepatocytes and not a tumor. Some studies have found that estrogen may have an effect on the growth and bleeding of FNH. The average diameter of focal nodular hyperplasia does not exceed 5 cm, and rarely exceeds 10 cm. Patients have no typical clinical presentation. Abdominal ultrasound can visualize the lesion but does not have diagnostic value to confirm the diagnosis. In contrast, abdominal enhancement CT or abdominal enhancement MRI have typical imaging features and can make a definite diagnosis. Once the diagnosis of FNH is confirmed, observation can be continued. However, if the diagnosis is not clear enough to exclude hepatocellular carcinoma, or if there is a history of hepatitis or elevated methemoglobin, surgical treatment is required. For those with a clear diagnosis of FNH but progressive enlargement, B ultrasound-guided percutaneous radiofrequency ablation is the preferred minimally invasive treatment if there is a pathway for extracorporeal puncture as observed by ultrasound. Third, hepatocellular adenoma hepatocellular adenoma is a rare solid lesion of the liver with the possibility of malignant lesions. They are prevalent in women. Patients with hepatocellular adenoma often have obvious clinical symptoms, the most common complaint being pain in the upper abdomen or right upper abdomen, which may radiate to the subscapular region, in addition to hypotension, shock, intra-abdominal hemorrhage and even death in severe cases. The adenoma may rupture or bleed during pregnancy or within 6 weeks after delivery. When rupture or hemorrhage occurs, significant abdominal pressure is seen on examination. A large liver or abdominal mass is a common positive sign. If the lesion is not bleeding internally, the results of abdominal ultrasound, CT and MRI are not specific. Once hepatocellular adenoma is diagnosed, surgical resection should be considered. The segment, lobe or half of the liver in which the adenoma occurs is removed. IV Simple hepatic cysts are thought to be benign occupying lesions caused by congenital intrahepatic bile duct defects. There are usually no clear clinical symptoms. Abdominal ultrasound can confirm the diagnosis of hepatic cysts. Once diagnosed, liver cysts do not require special treatment or medication. However, when the cyst is larger than 10 cm or the patient has symptoms of compression, it needs to be treated and laparoscopic opening and drainage of the liver cyst can be considered. The four benign occupying lesions of the liver introduced above, except for hepatocellular adenoma, have no typical clinical manifestations and are easily overlooked. If you find any abnormalities through examination, do not panic and seek medical attention in time. If no special treatment is needed, follow the doctor’s instructions and observe closely in daily life, with regular checkups and follow-ups. I am in charge of my health, and I wish you all can be the master of your own health!
