“…However, due to the size and septal structures, some tumors are unable to be correctly diagnosed as a benign simple cyst and the surgical resection is recommended. Since the tumor marker such as CA19-9 increases even in benign tumors [15, 16], it is difficult to make a decision by the serological findings. In these cases as shown in the figures, the puncture of cystic fluid can also be considered, however, due to the numerous of false negative, examination of cyst puncture fluid is hard to be recommended as useful.…”

“…In these cases as shown in the figures, the puncture of cystic fluid can also be considered, however, due to the numerous of false negative, examination of cyst puncture fluid is hard to be recommended as useful. Moreover, in biliary cystadenocarcinoma, there is possibility of peritoneum sowing by puncture, and even by risking the complications, it is concluded that it is not necessary to perform cyst puncture [15–17]. In recent years, there have been reports that contrast-enhanced US with sonazoid is useful to the diagnosis, because it reveals the clear boundary of a cyst wall and circumference hepatic tissue in early vascular phase and the defect area in Kupffer's phase in biliary cystadenocarcinoma [18].…”

The hepatic cyst is a common benign liver tumor, and no surgical treatment is necessary. However, it is difficult to correctly diagnose the giant hepatic cyst containing the solid septal structures inside, from the malignant cystadenocarcinomas. The various imaging modalities such as computed tomography, magnetic resonance imaging, and ultrasonography, have been developed and are useful for the diagnosis of these liver tumors. Reviewing the other reports in this paper, the combination of more than 2 modalities will help to diagnose these tumors; however, the malignant potential is unable to be excluded if the tumor is huge. Therefore, the surgical resection should be considered for the huge hepatic cysts with septal structures if the correct diagnosis is unable to be made. For example, when the hemorrhages cause the granulation in the septa which often shows neovascularization, the imaging modalities are unable to define this situation from the malignant tissue with hypervascularity. Therefore, with the careful review of other reports, we conclude that if the imaging studies show the possible malignant potential or the sizing-up is marked, the surgical treatment should be considered with the consent from the patients.

Hemothorax with a High Carbohydrate Antigen 19-9 Level Caused by a Bronchogenic Cyst

et al. 2014

View full text Add to dashboard Cite

A 58-year-old man presented with right-sided chest pain. Radiography and computed tomography showed a pleural effusion in the right chest and a mass in the right hilum. Thoracentesis showed a hemothorax. The carbohydrate antigen (CA) 19-9 level in the pleural effusion was very high, requiring differentiation from malignancy. Positron emission tomography showed no significant fluorodeoxy glucose (FDG) accumulation. Magnetic resonance imaging revealed a cystic lesion. The tumor was resected for both a diagnosis and treatment. A pathological examination demonstrated a bronchogenic cyst. An immunohistochemical study suggested that the cyst was the source of the hemothorax and the high CA19-9 level.
