Computed tomography with virtual bronchoscopy shows inner shape of trachea and major bronchi with three-dimensional images. Virtual bronchoscopy can be used in cases of suspected foreign body aspiration. Virtual bronchoscopy shows the exact location of the obstructive lesion before conventional bronchoscopy. If the chest radiography is normal or suggests aspirated foreign body, virtual bronchoscopy can be considered before conventional bronchoscopy. We experienced a case of false-tooth foreign body extracted under bronchoscopy. In this case, virtual bronchoscopy was made retrospectively giving useful information about shape and orientation regarding foreign body.

There are various types of foreign body reactions, such as inflammation, edema, fluid collection, hematoma, infection, abscess and granulomas. There are various imaging findings according to types of foreign bodies and depending on the lapse of time. Therefore, correct diagnosis of a foreign body reaction is difficult and easily confused with soft tissue neoplasm. The MRI is ideal for the detection of foreign bodies regardless of radiolucency or acoustic impedance. It is especially very useful in the evaluation of the surrounding tissue reaction. The authors report a case of a 26-year-old female patient with both forearm swelling due to self-injection of a mixture of powdered tablets and saline. The lesion shows numerous internal T1 and T2 dark signal intensity micro-spots with surrounding fluid collection, which are diagnosed as foreign bodies with surrounding inflammatory changes during an operation.

Purpose: The management and clinical course in pediatric patients who had ingested foreign body were investigated retrospectively to evaluate the frequency and factor associated with successful removal of fishbone foreign body. Methods: Based on the medical records of patients younger than 15 years old who visited emergency room because of foreign body ingestion from January 1999 to December 2012, the authors reviewed clinical characteristics including type of ingested foreign bodies, time to visits, managements and complications. Results: Fishbone (50.1%) was the most common ingested foreign body in children. Among 416 patients with ingested fishbone, 245 (58.9%) were identified and removed using laryngoscope, rigid or flexible endoscope from pharynx or upper esophagus by otolaryngologists and pediatric gastroenterologists. The kind of ingested fish bone in children was diverse. The mean age of identified and removed fishbone group was 7.39 years old, and higher than that of unidentified fishbone group (5.81 years old, p<0.001). Identified and removed fishbone group had shorter time until hospital visit than the unidentified fishbone group (2.03 vs. 6.47 hours, p<0.001). No complication due to ingested fishbone or procedure occurred. Conclusion: Older age and shorter time from accident to hospital visit were the different factors between success and failure on removal of ingested fish bone in children.

Objective This study was conducted to gather basic information of 3D CT in detecting and gaining information of esophageal foreign body (FB) models. Materials and Methods The chest model was made using PVC bottle, rubber balloon and plaster. Fish bone, Persimmon stone were used to mimic foreign bodies of esophageal model. The foreign body models were inserted into the balloon removing air from it and the balloon was sealed. The esophageal FB model was inserted into the chest model. The remaining space in the chest model was filled with fish paste and water to simulate soft tissue around esophagus. CT of chest model was reconstructed three-dimensionally by Rapidia software to make images of foreign body models. The axial CT, MPR image and VOI image were compared with real foreign body materials as to shape, size, location and orientation. Results Esophageal FB models were easily made. CT data gave good 3D images and showed realistic foreign body materials. Conclusion The results indicate the usefulness of 3D CT technique to help in diagnosis of esophageal foreign body models.

Direct injection of foreign material, such as liquid paraffin and silicone, into the breast can induce a foreign body granulomatous reaction and fibrosis, resulting in hard, nodular breast masses and architectural distortion that can mimic neoplasm. Conventional methods, including physical examination, mammography, and ultrasonography are of little use to differentiate between foreign body-induced mastopathy and breast cancer. In patients with foreign body injection such as breast augmentation, dynamic contrast enhanced MR imaging is an excellent imaging modality. Here, the authors report the MR imaging and pathological findings of ductal carcinoma in situ (DCIS) with multicystic changes in a 41-year-old woman with a previous history of interstitial mammoplasty by paraffin injection.

A-50-year-old male patient presented with complaint of tenderness on the left malar area after traffic accident. Our first impression on him was zygomatic fracture, we did radiologic work-up and physical examination on him. But, on the computed tomography scan, there was no fracture or discontinuity on his facial bone. The computed tomography scan was revealed a 4-cm long foreign body in left maxillary sinus with a large amount of fluid collection. After thorough history taking from him, we reveal the patient had a history of trauma 30 years back on the left zygomatic area with a chopstick. The foreign body was removed via transoral approach with the endoscopic assist. There was no complication after operation.

This research is intended to inquire any discrepancy depending on the variables such as types, geography and size of hospitals of Korea in order to develop differentiated marketing strategy and to investigate how the aforementioned variables affect the management performance such as the increase in the number of foreign patients, their willingness to re-visit, the increase in profit and etc. The survey for this research was conducted for five weeks from July 10th 2014 to August 30th 2014 with 251 participants in charge of foreign patient attraction for 161 domestic hospitals. As the method of the research, a hypothesis was first established based on previous studies, followed by the incorporation of self-administered questionnaire to confirm the formulated hypothesis. Frequency analysis and ANOVA analysis were used to analyze the result of the survey. The outcome of the research and the implications are as follows. First, according to the demography of the persons-in-charge of foreign patient attraction, the proportion of female was superbly high by 76.5%. As for the age, those in their 30s were highest in proportion. Finally, for the education level, college graduates took up the largest portion by 46.5%. Second, in respect to the hypothesis assuming the difference in performance depending on the types of hospitals, national university-affiliated hospitals showed the highest level of the increase in foreign patients by the average of 3.25. Third, in respect to the hypothesis assuming the difference in performance based on geographical position, it was confirmed that hospitals in Ulsan City experienced the largest growth in the number in foreign patients. Fourth, in respect to the sizes of hospitals, those with 201 to 300 sickbeds showed the highest increase by the average of 3.45. The implication of the above research outcome indicates that while the number of foreign patients visiting Korea for medical purposes is on the rise, the number of professionals in place with necessary knowledge and capacity is insufficient and requires improvement.

We report the case of a seven-year-old boy with an ingested foreign body, which was retained within the appendix for a known duration of ten months, ultimately requiring appendectomy. The ingested foreign body was incidentally discovered by abdominal x-ray at an emergency room visit for constipation. Despite four bowel cleanouts, subsequent x-rays showed persistence of the foreign body in the right lower quadrant. While the patient did not have signs or symptoms of acute appendicitis, laparoscopic appendectomy was performed due to the risk of this foreign body causing appendicitis in the future. A small metallic object was found within the appendix upon removal. This case highlights the unique challenge presented by foreign body ingestions in non-verbal or developmentally challenged children and the importance of further diagnostic workup when concerns arise for potential retained foreign bodies.

Traditional surgery to remove foreign bodies in the face carries a risk of postoperative morbidity with an injury to various anatomical structures, particularly the facial nerve and parotid duct and gland. Endoscopy can be a great aid in the removal of foreign bodies in the maxillofacial region. Surgical intervention using endoscope and/,or intraoperative images can be minimized, allowing the safe and precise removal of foreign bodies, and saving operating time. We report a case of the use of an endoscope and C-arm fluoroscopy guidance system to remove a very small foreign body.
