PURPOSE: To assess the role and efficacy of radiologic intervention in the adult patients with esophagobronchial fistula. MATERIALS AND METHODS: Radiologic intervertion was performed in 4 patients with esophagobronchial fistula. We tried direct occlusion of fistula tract by glue(histoacylate 0.4cc + lipiodol 0.3cc) and coil in 2 patients and performed presurgical wire insertion by using 8F curved catheter via esophageal opening of fistula tract. The latter procedure was carled out to detect the fistula tract easily at operation. RESULTS: Direct occlusions of fistula tract by glue and coil were performed only to fail in 2 patients. Pre-surgical wire incertion by using 8F curred catheter under guidance of fluroscopy in 3 patients were helpful in detecting fistula tract at operation. CONCLUSION: Direct occlusion of the fistulous tract in esophagobronchial fistulas was ineffective. However, presur- gical wire insertion by using cured catheter under fluroscopy guidance is helpful to detect the fistula tract easily at operation.

Lipiodol based conventional transarterial chemoembolization (TACE) is a standard of care for unresectable, non-invasive, and multinodular Hepatocellular carcinoma (HCC)s. The procedure relies on the intra-arterial administration of lipiodol/cytotoxic agent emulsion followed by the infusion of embolic material. Lipiodol, with its oily nature and radiopacifying properties, is in the center of the TACE procedure. Unstability and unpredictable therapeutic effect of hydrophilic cytotoxic drugs emulsified in the lipiodol and technical problems lie beyond the control of clinicians. Thus, interest in the properties and respective roles for lipiodol in the management of HCC is essential for the clinicians.

OBJECTIVES: To evaluate MRI findings of non-recurrent hepatocellular carcinomas with lipiodol uptake (LHCCs) treated with transarterial chemoembolization. METHODS: 28 LHCCs were divided into two groups according to amount of lipiodol uptake and tumor size, retrospectively. According to amount of lipiodol uptake, HCCs were classified into group A with dense lipiodol uptake (more than 90%) and group B with partial lipiodol uptake (between 50% and 90%). For HCC size analysis, group I was defined by a longest diameter of less than 2 cm, and group II was defined by a longest diameter of greater than or equal to 2 cm. RESULTS: In group A (n=16), eight LHCCs showed high signal intensity (SI) on T2-weighted images (T2WI), ten LHCCs showed low SI on T1-weighted imaged (T1WI), six LHCCs showed decreased SI at higher b value of diffusion-weighted images (DWI). In group B (n=12), six LHCCs revealed high SI on T2WI, six LHCCs revealed low SI on T1WI, ten LHCCs decreased SI at higher b value of DWI. As compared with tumor size and SI, six of 12 LHCCs in group I and eight of 16 LHCCs in group II showed high SI on T2WI. Six LHCCs in group I and ten LHCCs in group II showed low SI on T1WI. All LHCCs were not enhanced. CONCLUSION: Signal intensities of LHCCs were variable, but more than half of LHCCs showed high SI on T2WI, low SI on T1WI, decreased SI at higher b value of DWI, regardless of lipiodol uptake or tumor size.

Inflammatory myofibroblastic tumor (IMT) of the liver is a very rare lesion that has radiologic similarity with malignant liver tumor. Differential diagnosis of IMT from a malignant lesion of the liver is very important because surgical resection is not mandatory for IMT. Lipiodol computed tomography is a very sensitive and specific diagnostic tool for hepatocellular carcinomas (HCC). Herein, we describe a case of IMT that had dense lipiodol uptake in the tumor and mimicked HCC. To our knowledge, previously, only one case of IMT with dense lipiodol retention has been reported.

PURPOSE: To evaluate the effectiveness of transcatheter arterial chemoembolization(TACE) as a preoperative treatment for initially unresectable hepatoblastomas. METHODS: From January 1995 to July 1999, we identified two boys and three girls(age range: 5- 27 months; mean age: 12 months) with pathologically-confirmed hepatoblastoma. To assess response to treatment, we utilized an identical TACE procedure for all the patients. A second TACE procedure was performed 3 weeks after the first TACE procedure and patients underwent tumor resection approximately 1 month following the second TACE procedure. The therapeutic responses to TACE were assessed by measuring of tumor size, shape, observation of tumor properties using abdominal computed tomography(CT), gross and microscopic pathologic findings, levels of alpha- feto protein(AFP) and clinical adverse events to TACE. RESULTS: In these patients, hepatoblastomas showed marked reductions in tumor size. Massive tumor necrosis and homogeneous distribution of lipiodol created a clear margin bordered by surrounding normal liver tissue. At initial diagnosis, the mean AFP leve1=867Ang/mL, 47.4ng/mL after second TACE, and 8.6ng/mL at 6 months after surgical resection. Transient fever was ob- served following TACE and elevations of levels of AST and ALT were observed but these normalized 2 weeks following TACE. No major complications were associated with TACE. CONCLUSION: We suggest that preoperative TACE is an effective, safe, and useful method for patients with initially unresectable hepatoblastoma.

PURPOSE: To evaluate intrahepatic nodular lesions detected on CTAP but not on conventional contrast CT in regard to its relationship with satellite nodules or borderline malignancies. MATERIALS AND METHODS: From June 1991 to March 1994, CTAP was undertaken in 132 cases with confirmed hepatocellular carcinoma(HCC), of which 35 cases having 82 lesions were suitable for analysis(excluding the cases which had no follow-up studies, showed segmental abnormal portal perfusion, no additional lesions and, or inumerable lesions). The CTAP findings were compared with those on artery dominant imaging studies (angiography, DSA, bolus dynamic CT, arterial CT, Lipiodol CT) taken during the same period(to confirm the presence of lesions) and the findings on follow-up imaging studies(to assess the developemerit of malignancy). RESULTS: Arterial vascularity was identified in 35 of 82 lesions(42.7%) on arterial dominant imaging studies. Developement into malignancy was identified on follow-up imaging studies in 25 of remained 47 lesions(53.2%). CONCLUSION: The total positive predictive value of nodules on CTAP was 73.2%(35+25/82), but the predictive value for HCC by follow-up only was 53.2%. Given'the difficulties in detecting intranodular arterial flow and the short follow-up duration in many patients, the actual positive value might be higher.

Seventeen cases of chronic dacryocystitis were studied by performing dacryocystography, using Pantepaque or Lipiodol as the dye. The youngest patient was 22 years of age, the oldest 66 years. Two cases were in male sex and remaining twelve were in females. Of these 17 cases, the chronic dacryocystitis was present on both sides in ten cases, on the right side in 4 and on the left side in 3. Daryocystograms showed that: 1. The most common site of obstruction was the neck of the sac(61.5%). 2. The obstruction was total and complete, except one case. 3. The lacrimal sac shown by dacryocystography as follows: a) a large sac with atony suggesting several years of suppurative inflammation. b) a samll shrunken sac suggesting several years of mild inflammation. c) normal sized sac with irregular outline suggesting recent acute exacervation of the disease. d) normal sized sac suggesting short duration of chronic mild inflammation. 4. Two cases of fistula and one case of diverticulum were observed. 5. There were nonvisualization of five cases of the lacrimal sac because of obstruction of canaliculi or ampulla.
