Parenchymal Air-Fluid Level in Emphys ematous Lung: A Report of Two Cases

We report two cases of parenchymal air-fluid level in emphysematous lungs. Plain chest radiograph showedpneumonic consolidation with an air-fluid level. HRCT in the supine position showed intrapulmonary fluidcollection with an air-fluid level, which moved to the dependent portion when the patient was in the proneposition. When pneumonia developed in severe emphysematous lungs, a movable parenchymal air-fluid level can bevisualized, though the presence of this on plain chest radiographs cannot be interpretated as hydropneumothorax.

Ultrasonographic Analysis of Normal Thymus in Infants

PURPOSE: To analyse the ultrasonographic findings of normal thymus in infants and determine the pathologic findings. MATERIALS AND METHODS: Forty two infants without a history of chronic disease, tumor or steroid therapy were scanned in the axial planes with a 7.0 MHz sector transducer. Bilaterality, homogeneity, and the shape and intensity of thymic echogenicity were analysed; shapes were classified as one of three types, namely bilobate, quadrangular or triangular. The intensities of thymic echogenicity were compared with those of the liver and spleen under the same conditions (time-gain compensation, depth and gain). RESULTS: Bilaterality was seen in 36 cases, homogeneity in 35, homogeneity and bilaterality in 29, inhomogeneity and bilaterality in seven, and homogeneity and unilaterality in six. No case showed inhomogeneity and unilaterality. The shape was bilobate in 23 case, quadrangular in 13 and triangular in six, while the outer border was convex in 29 cases and straight in 13. In no case was echogenicity of the thymus greater than that of the liver or spleen. Transverse diameters were 21-47mm (mean, 37.0mm; SD, 9.4mm) and depths were 10-37.5mm (mean, 25.8mm; SD, 5.9mm). CONCLUSION: The usual findings of normal thymus in infants are bilaterality and homogeneity, convex or shaight outer border, and echointensity less than or equal to that of the liver and spleen. The possibility of thymic pathology is suggested when ultrasonography shows unilaterality, inhomogeneous echogenicity, and echogenicity greater than that of the liver and spleen.

Agenesis of the right lobe of liver: a case report

Congenital agenesis of the right lobe of liver is a rare anomaly and only 33 cases have been reported. CT showed absence of the right lobe of liver and compensatory hypertrophy of the other lobe. We report the CT findings of a new case of this anomaly with a review of the literatures.

Analysis of branching patterns of middle hepatic artery using A-P and oblique view hepatic angiography

A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refered to size and location of quadrate lobe in CT and SMA portography We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among the 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately one from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was seen. MHA WAS not found as an accessory or replaced artery except as replaced common hepatic artery.

Continuous Irrigation in the treatment of the Corneal Alkaline Burn and Serpent Corneal Ulcer

The auther had utilized the continuous irrigation with saline and antibiotics to 1 case of serpent corneal ulcer and 2 cases alkaline burn by Lippas' original technique. Two cases of alkaline burn were healed up without any complications and one case of serpent corneal ulcer showed relatively good result. According to review through a few literature, the method of continuous irrigation is much better one than any other systemic or local administration of the drug to the particular external ocular disease.
