Authors retrospectively analyzed the CT findings of cystic tumors of the mediastinum in surgically confirmed13 cases at Seoul National University Hospital during the recent 3 years from August 1980 to August 1983. Theresults are as follows: 1. Among 13 cases, bronchogenic cyst and cystic teratoma were 4 cases respectively,pericardial cyst were 2 cases, and thymic cyst and cystic hygroma was 1 case respectively. 2. CT No. of 4bronchogenic cysts was in the range of 12-112 HU, 3 cases among them had thick-walled capsules. CT No. of 4 cysticteratomas was in the range of

Pulmonary ligament consists of 2 serosal layer of pleura that connect the lower lobe to the mediastinum.Author analyse and present CT appearance of pulmonary ligament of the 40 normal and abnormal patients on the basisof anatomic knowledge from the cross section of cadaver. Left pulmonary ligament is more frequency visualized thanthe right. The most important CT landmark in localizing pulmonary ligament is the esophagus where the ligamentattaches on its lateral wall. Pitfalls in CT identification of pulmonary ligament are right phrenic nerve andright pericardiacophrenic vessels which emerge from the lateral wall of the IVC and wall of the emphysematousbulla in the region of the pulmonary ligament.

Computed tomographic findings in fifteen cases of anterior mediastinal teratoma are presented and comparedwith radiographic , pathologic findings. Specific CT characteristics of anterior mediastinal teratoma arepredominantly fatty mass with a denser dependent element and globular calcification in a solid protuberance intothe cystic cavity. Six cases presented above described characteristic CT findings. Four cases presented waterdensity mass with surrounding thick wall. Fat and calcific densities were present in nine and seven respectively,so these findings are frequently absent. Thick wall was present in all cases. So thick walled cyst even in theabsence of fatty or calcific densities is highly suggestive of anterior mediastinal teratoma.
Teratoma

Fat containing masses, except mediastinal lipomatosis, of the thorax are uncommon. In spite of uncommonoccurences, as CT can detect not only the fat content but also the presence and character of the non-fattycomponent of the mass, accurate preoperative diagnosis can usually be made in most cases of fat containingmediastinal masses. Authors report 6 cases of fat containing mediastinal masses, that were diagnosedpreoperatively by CT scan, comprising 2 cases of limpoma(combined with plexiform neurofibroma in a case), 1liposarcoma, 1 thymolipoma, and 2 cases of omental hernia through Morgagni foramen.

The fungus aspergillus can cause a variety of pulmonary disorders. Aspergilloma is a noninvasive aspergillus colonization of virtually any type of preexisting pulmonary cavity or Cystic space. Invasive pulmonary aspergillosis is serious, usually fatal infection in patients being treated with immunosuppressants or who have chronic debilitating disease. Allergic bronchopulmonary aspergillosis is charaterized clinically by asthma, blood and sputum eosinophilia and positive immunologic reaction to aspergillus antigen. Awareness of the radio-graphic and CT findings of pulmonary aspergillosis is important in making the diagnosis of aspergillus-caused pulmonary disorders. In this pictorial essay, we illustrated various radiological findings of pulmonary aspergillosis focused on CT findings correlated with gross pathologic specimens.
