The purpose of this study is to evaluate the variation of radiation dose distribution for liver tumor located in liver dome and for the interest organs(normal liver, kidney, stomach) with the pencil beam convolution (PBC) algorithm versus anisotropic Analyticalal algorithm (AAA) of the Varian Eclipse treatment planning system, The target volumes from 20 liver cancer patients were used to create treatment plans. Treatment plans for 10 patients were performed in Stereotactic Body Radiation Therapy (SBRT) plan and others were performed in 3 Dimensional Conformal Radiation Therapy (3DCRT) plan. dose calculation was recalculated by AAA algorithm after dose calculation was performed by PBC algorithm for 20 patients. Plans were optimized to 100% of the PTV by the Prescription Isodose in Dose Calculation with the PBC algorithm. Plans were recalculated with the AAA, retaining identical beam arrangements, monitor units, field weighting and collimator condition. In this study, Total PTV was to be statistically significant (SRS: p=0.018, 3DCRT: p=0.006) between PBC and AAA algorithm. and in the case of PTV, ITV in liver dome, plans for 3DCRT were to be statistically significant respectively (p=0.013, p=0.024). normal liver and kidney were to be statistically significant (p=0.009, p=0.037). For the predictive index of dose variation, CVF ratio was to be statistically significant for PTV in the liver dome versus PTV (SRS r=0.684, 3DCRT r=0.732, p<0.01) and CVF ratio for Tumor size was to be statistically significant (SRS r=-0.193, p=0.017, 3DCRT r=0.237, p=0.023).

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

Although intrathoracic liver in association with a congenital diaphragmatic hernia has been well documented, the finding of intrathoracic ectopic liver tissue in the presence of an intact diaphragm is an extremely rare congenital anomaly. We have experienced a case of intrathoracic ectopic liver without any diaphragmatic hernia. A 37-year-old woman was admitted for the treatment of an incidentally detected right lung mass, A chest computed tomography scan revealed a right lower lobe lung mass close to the diaphragm, and this was suspicious for bronchial carcinoid tumor. Upon surgery, 2 round solid masses $3.5{\times}3.5 cm$ and a $2.0{\times}2.0 cm$ in size were noted, with their bottoms attached to the diaphragm dome. The masses were completely resected. Histologically, they were confirmed to be intrathoracic ectopic livers. The patient had an uncomplicated postoperative course.

Caustic ingestion can produce a progressive and fatal injuries to esophagus, stomach and other organs. Reported exposure to acetic acid results injuries to gastrointestinal tract, hemolysis and disseminated intravascular coagulation is general, but causing hepatic necrosis by direct injuries are rare. A 47-year-old man visited our emergency medical center complaining odynophagia and abdominal pain after ingesting glacial acetic acid ($99\%$) with suicidal ideation. At the time of arrival, the patient complained mild abdominal pain but a few hours later the patient complained severe abdominal pain with markedly elevated liver enzymes. The Abdominal Computerized Tomography showed diffuse gastric wall edema and density of wedge shaped hypodense area in right hepatic dome showing focal hepatic necrosis without significant inflammation. This seems likely to be a direct effect of the noxious agent on hepatocyte involving the portal circulation.
