Communicating bronchopulmonary foregut malformations are rare tracheobronchial anomalies characterized by a fistula between an isolated portion of respiratory tissue and the esophagus or stomach. We describe a case of CBFM in which chest radiography revealed total haziness in the right lung field. The diagnosis was confirmed by esophagography.

BACKGROUND/AIMS: Due to widespread use of computerized tomography (CT) scan to examine patients with variable disease or complaints, detection of incidental or unsuspected gastrointestinal abnormalities are not uncommon. Clinical significance of incidentally detected bowel wall thickening (BWT) on abdominal CT scan is uncertain at present. Despite the necessity for the clinical guidelines describing the evaluation of incidental bowel wall thickening on CT scan, there have been few studies concerning these radiological abnormalities. Our objective was to determine whether endoscopic evaluation is necessary for the evaluation of these abnormal findings. METHODS: This study evaluated one hundred and forty patients with incidentally detected BWT on abdominal CT scan in Inje University Sanggye Paik Hospital from 2001 to 2003. 102 patients of those were proceeded by endoscopic evaluation. Forty-eight patients had received upper endoscopy, 26 patients had colonoscopy, while 28 patients had sigmoidoscopy. RESULTS: Endoscopic work up revealed significant abnormalities in 83% of patients with incidental findings of the distal esophagus, 73% of patients with thickening of the stomach, 35% of patients with thickening of the right colon, and 71% of patients with thickening of the sigmoid colon and rectum. CONCLUSIONS: Although significant pathologic findings are less common in thickening of the right colon than other bowel wall thickening, all of these incidental findings on CT scan warrant further endoscopic evaluation.

Intramural esophageal dissection (IED) is an uncommon disorder characterized by separation of the mucosal and submucosal layers of the esophagus. Iatrogenic intervention is the most common cause of IED, but spontaneous dissection is rare. We report an unusually complicated case of spontaneous IED that involved the full-length of the esophagus that necessitated surgical intervention due to infection of the false lumen. In this case, chest computed tomography successfully established the diagnosis and aided in pre-operative evaluation with the use of various image post-processing techniques.

PURPOSE: We evaluated the absorbed doses to the organs and calculated the effective doses when using the digital panoramic radiography. MATERIALS AND METHODS: The absorbed dose averages in major organs of oral and maxillofacial region were measured using the Dental head phantom (CIRS Co., USA), (n)Li(2)B(4)O(7) TLD chip and UD-716AGL dosimeter (Matsushita Electric Industrial Co., JPN) when performing indirect and direct digital panoramic radiography. Effective doses were calculated from correspond to ICRP 2007 recommendations for two panoramic radiography. RESULTS: The absorbed dose average on indirect and direct digital panoramic radiography was highest in parotid glands as measured 1259.6 mGy and 680.7 mGy respectively. Absorbed dose average in another organs were high in order of esophagus, submandibular gland, tongue and thyroid gland on both types of digital panoramic radiography. The absorbed dose average was higher on indirect type than direct one (p<0.05). The effective dose was higher on indirect type than direct one as measured 13.28 mSv and 8.70 mSv respectively. CONCLUSION: The absorbed doses in salivary gland and oral mucosa were high. However, thyroid gland also demands the attention on radiography due to high tissue weighting factor in spite of the low absorbed dose.

A sharp, impacted fish bone in the esophagus is an indication for urgent endoscopy. Endoscopic removal of such an object is a challenging task. An endoscopic protector hood is then used to remove the object. However, an endoscopic hood protector is not always available. In a patient with a large hiatal hernia, the protector hood may not return to the original shape when it passes through the gastroesophageal junction and therefore may not properly protect the esophageal mucosa from the sharp foreign body. In our case, it was impossible to deploy the endoscopic hood protector through the gastroesophageal junction despite multiple attempts. We propose an alternative solution for such cases. We safely removed a large sharp-edged flat fish bone that was folded and compressed using a detachable snare after releasing and pushing the fish bone into the stomach using an endoscope equipped with a transparent cap used for dilating the esophageal wall. This method of using an endoscopic cap and detachable snare is a safe, useful alternative for endoscopically removing a large sharp-edged flat foreign body from the upper gastrointestinal tract. This alternative technique has not been reported in the English medical literature.

Esophageal duplication cysts are rare congenital lesions that occur as a result of a failure in the tubulation of the esophagus. They are most frequently single, tubular, or cystic. They may cause compressive symptoms or may be discovered incidentally on chest radiographs. They become symptomatic when complications develop. Symptoms often are related to the location of the duplication; esophageal lesions can create respiratory difficulties. The definitive diagnosis of esophageal duplication cysts requires the pathological evaluation of the cyst after surgical removal. We experienced a rare tubular esophageal duplication, in a 2-month old girl who presented with fever and grunting. This is the first reported case in which the sequence of events of ruptured tubular esophageal duplication with empyema, mediastinitis and aneurysm occured.

Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

OBJECTIVE: The aim of our study was to describe and compare the radiologic findings of esophageal leiomyomas. MATERIALS AND METHODS: The chest radiographic (n = 12), esophagographic (n = 12), CT (n = 12), and MR (n = 1) findings of surgically proven esophageal leiomyomas in 12 consecutive patients [ten men and two women aged 34 - 47 (mean, 39) years] were retrospectively reviewed. RESULTS: The tumors, surgical specimens of which ranged from 9 to 90 mm in diameter, were located in the upper (n = 1), middle (n = 5), or lower esophagus (n = 6). In ten of the 12 patients, chest radiography revealed the tumors as mediastinal masses. Esophagography showed them as eccentric, smoothly elevated filling defects in 11 patients and a multilobulated encircling filling defect in one. In 11 of the 12 patients, enhanced CT scans revealed a smooth (n = 9) or lobulated (n = 2) tumor margin, and attenuation was homogeneously low (n = 7) or iso (n = 4). In one patient, the tumor signal seen on T2-weighted MR images was slightly high. CONCLUSION: Esophageal leiomyomas, located mainly in the middle or distal esophagus, are consistently shown by esophagography to be mainly eccentrically elevated filling defects and at CT, lesions showing homogeneous low or isoattenuation are demonstrated.
