Abstract

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 -24 -20 HU. All of them had thick-walled capsules. CT No. of 2 pericardial cysts wasin the range of 12-25 HU. CT No. of a thymic cyst was in the range of -10 -23 HU. CT No. of a cystic hygroma wasabout 24 HU. 3. With CT, cystic tumors of mediastinum are easily diagnosed by its shape, location and typicalwater density mass. But bronchogenic cyst, because of its mucoid contents, may often have CT No. above thoseusually considered charactersitic of cyst. So we must consider bronchogenic cyst in differential diagnosis even ifCT No. is high, if the lesion is in typical locaiton and the shape is round or ovoid.
