3.An A to Z of Lipiodol Beyond the Clinical Practice in the Management of Hepatocellular Carcinoma.
Journal of Liver Cancer 2015;15(2):84-87
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.

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.

Transcatheter arterial chemoembolization (TACE) is one of the most common palliative treatment modalities for patients with advanced hepatocellular carcinoma (HCC). TACE is an invasive procedure associated with several potential complications of varying severity. A pulmonary embolism after TACE for HCC is a rare complication. We report a case of pulmonary Lipiodol embolism after a third TACE resulting in death.

PURPOSE: To assess the malignant potential of small(< or =15mm) portal defects seen on CT arterial portography,the findings of CT hepatic arteriography and lipiodol CT CT were reviewed. MATERIALS AND METHODS: In 91 patientswho underwent both CTAP and CTHA, small portal defects were re-viewed for frequency, multiplicity and location. Weprospectively evauluated changes in the size and enhance-ment pattern of malignant lesions on follow up CTaccording to density on CTHA, location, lipiodol deposits on lipiodol CT, and multiplicity. RESULTS: Among the 91patients, 102 small defects were defected in 42 patients(46%). Small portal defects were benign, malignant, and ofundetermined malignant potential in 77%, 20% and 3% of cases, respectively. Small portal defects that werehyperattenuated on CTHA, and lipiodol deposits on lipiodol CT, were malignant in 42% and 70% of cases,respectively. Location and multiplicity did not show statistically significant variation between benign andmalignant defects. CONCLUSION: Small portal defects are common and there is a high probability that portaldefects smaller than 15mm are benign, even in patients with a known hepatic mass and defect that washyperattenuated on CTHA. If a small defect showed lipiodol deposit on lipiodol CT, malignancy must be suspected.

7.Clinical Dacryocystography.
Journal of the Korean Ophthalmological Society 1977;18(4):379-384
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.

PURPOSE: The purpose of this study was to evaluate the utility of renal CT scanning and to histologicallycorrelate renal damage induced by renal arterial infusion of 0.2 ml/kg of doxorubicin-lipiodol emulsion. MATERIALS AND METHODS: Renal CT scans of 20 rabbit kidneys were obtained 15 days after transcatheter arterialchemoembolization and were classified into four grades, as follows : Grade 0 - no fleck, Grade 1 - one to threenodular flecks ; Grade 2 - four or more nodular flecks, or one semilunar fleck ; and Grade 3 - two or moresemilunar flecks. The percentage of histological section occupied by lesion was determined using squared paper,and compared with the grades determined on the basis of CT. RESULTS: The histologic findings were interstitialinflammatory cell infiltration, intratubular lipiodol droplets, dystrophic calcification, and cellular necrosis.The mean sizes of grade 0, 1, 2 and 3 histological lesions were 2.2%(n=5), 4.5%(n=4), 21.9%(n=7), and 24%(n=4),respectively. Grades 0 and 1 accounted for nine cases(3.2%), while grades 2 and 3 accounted for 11(22.6%) ; thisdifference was statistically significant(p<0.01). CONCLUSION: CT findings showing nodular or semilunar flecks 15days after infusion into the renal artery of doxorubicin-lipiodol emulsion correlate with the size of the damagedkidney, as seen on histological specimens.

The Ewha Medical Journal 2016;39(4):110-117
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.
