Journal of the Korean Radiological Society.1992;28(1):112-114. doi:10.3348/jkrs.1992.28.1.112

Cholesterol polyps are the most common cause of the polypoid lesions of the gallbladder shown by ultrasonography (US). Cholesterol polyps are usually attached to the mucosal surface of the viscus with delicate, filammentous stalks so that they can be easily detached. Recently, laparoscopic cholecystectomy has been introduced to treat various gallbladder diseases. We have experienced four patients with ultrasonographically typical gallbladder polyps, that were not detected in the pathologic specimens removed by laparoscopic cholecystectomy. In each patients, intraluminal suction preceded the laparoscopic cholecystectomy, and the suction was presumed to have resulted in the detachment of cholesterol polyps having delicated and fragile stalks.

Journal of the Korean Radiological Society.1992;28(1):108-111. doi:10.3348/jkrs.1992.28.1.108

Retroperitoneal duodenal rupture is rare and is often difficult to diagnose on the plain abdominal x-ray. From a review of the plain abdomen films of 21 cases with retroperitoneal duodenal rupture, confirmed by operation, pneumoretroperitoneum was revealed in 16 cases; Air in the peritoneum was manifested as a bubbly shadow in 12 cases, a renal halo in 9 cases, air shadow along the right psoas margin in 2 cases, air along the diaphragmatic crus in 2 cases and air in the right properitoneal fat in 2 cases, US and CT also revealed air bubbles and fluid collection around the right kidney. We recommend the plain abdomen as a useful diagnostic method for detection of pneumoretroperitoneum.

Primary pulmonary histiocytosis X: a case report.

Journal of the Korean Radiological Society.1992;28(1):101-103. doi:10.3348/jkrs.1992.28.1.101

Pulmonary histiocytosis X is a rare granulomatous disorder of unknown etiology that alters the interstitium of the lung. When confined to the lung, it is known as primary pulmonary histiocytosis X or eosinophilic granuloma of the lung. The chest radiograph shows characteristic nodular, reticular, and cystic abnormalities, which are most apparent in the upper and middle lung zones, but spare the costophrenic angles, The CT demonstrates innumerable small cysts with thin walls, and fine nodules. Recently we experienced pathologically proven primary pulmonary histiocystosis X in 35 years old male patients who had recurrent pneumothorax.

When bronchogenic carcinoma is coexisting with pulmonary tuberculosis, it is difficult to differentiate bronchogenic carcinoma from pulmonary tuberculosis radiologically. Thus, the object of this study is to define differential diagnosis of bronchogenic carcinoma by computed tomography. We analized CT scans of 27 patients with radiologic findings of pulmonary tuberculosis and mass of which twelve cases were pulmonary tuberculosis and fifteen cases were primary lung cancer. The location of parenchymal infiltration and the mass was the same in 60%(9/15) of the primary lung cancer in cases and 83%(10/12) of the pulmonary tuberculosis cases. The common location of the mass was the both upper lobes in 92%(11/12) of the pulmonary tuberculosis cases and 53%(8/15) of the primary lung cancer cases. The common locations of the mediastinal lymphadenopathy were 4R, 2R of the pulmonary tuberculosis cases and 4R, 10R of the primary lung cancer cases. In the feature of post enhanced lymph nodes, homogenous increased density was more frequent in primary lung cancer. Measurements of the maximum thickness part of the cavity wall was not a reliable indication of malignancy.

Bronchioloalveolar carcinoma: a variety of radiographic patterns.

Eun Young KANG ; Min Jin LEE ; Kyoo Byung CHUNG

Journal of the Korean Radiological Society.1992;28(1):89-94. doi:10.3348/jkrs.1992.28.1.89

Bronchioloalveolar carcinoma may present with a variety of radiographic and clinical appearances. The authors reviewed the radiographs of 17 patients with pathologically proven bronchioloalveolar carcinoma, retrospectively. Seven cases were of the localized form. Among the seven five showed a localized mass and two showed localized consolidation. Ten cases were of the diffuse form. Among the ten, three showed diffuse nodules, two showed diffuse consolidation, and five showed a combined pattern of nodules and consolidations. Progression of disease was observed in 9 patients. In these cases, localized forms progressed to a diffuse forms and nodular patterns progressed to a consolidation pattern. Seven cases of the diffuse form were given antituberculous medications on hospital admission. In summary, bronchioloalveolar carcinoma has varied radiographic patterns, and often mimicks other pulmonary diseases such as pulmonary tuberculosis.

Differential diagnosis between traction and compression of trachea.

Jae Young BYUN ; Seog Hee PARK ; Myung Ihm AHN ; Jong Woo KIM ; Yong Whee BAHK

Journal of the Korean Radiological Society.1992;28(1):84-87. doi:10.3348/jkrs.1992.28.1.84

The trachea is a cartilagenous and membranous tubular midline structure with parallel walls. Tracheal deviation may be caused either by traction toward the diseased hemithorax or by compression toward the normal side. Unless an obvious mass is observed radiographically, occasionally it can be difficult to decide whether the trachea has been pushed or pulled from its normal position in the mediastinum. We studied the differences between tracheal deviation patterns in 23 patients with fibroatelectatic pulmonary tuberculosis and 35 patients with elongated and dilated aortas. In cases of retraction of the trachea by fibroatelectatic pulmonary tuberculosis, the diameter of the deviated segment was greater than that of the normal segment and deviation of the wall adjacent to the fibroatelectasis from its normal position was greater than that of the opposite wall. In cases of compression of the trachea by the elongated and dilated aorta, the diameter of the diviated segment was smaller than that of the normal segment and deviation of the wall adjacent to the aortic arch from its normal position was greater than that of the opposite wall. We conclude that these differences between tracheal deviation patterns are useful signs for discriminating retraction from compression. Thus when the trachea is retracted, the deviation of the juxtalesional wall is greater than that of the lesion-free wall, and vice versa.

Various appearances of rib companion shadow mimicking a pathologic condition.

Journal of the Korean Radiological Society.1992;28(1):78-83. doi:10.3348/jkrs.1992.28.1.78

We have observed that the companion shadow of the upper rib may be misinterpreted as a small pnemothorax or pleural plaque associated with asbestosis. To observe the radiographic characteristics of the normal companion shadow, we analyzed, on the posteroanterior(PA) chest radiographs, the companion shadow of 50 normal cases. Factors such as occurrence on each rib, the sharpness of the margin, the relative position to the rib, the shape and the thickness were observed. Also, we analyzed the displaced pleura of 4 pneumothorax cases to differentiate their frndings from the findings of normal companion shadows. On 50 normal chest radiographs, 192 compaion shadows were observed on the first to fourth ribs. In 173 of those shadows, the visceral margin of the companion shadow on the second rib simulated pneumothorax more closely than those on any othe rivs due to its apical location and thinness. In six of 50 normal cases, the companion shadow on the first or second rib showed an inw rdly convex lower margin, mimicking pleural plaque. The compaion shadow was suggested on the plain chest radiograph by the following characteristics imultiplicity(47/50), thicker than normal pleura(3/4), persistent on serial filma with the same shape and specific location(4/4).
