Pigmentary dermarcation lines are boundaries between more deeply pigmented skin and areas of lighter pigmentation. We report 4 cases of pigmentary demarcation lines of pregnancy associated with erythema which developed in the third trimester of pregnancy and were symmetrically located in the buttock and posteromedial portion of the lower extremities. After delivery, the erythema disappeared within 3-7 days, followed by slow resolution of the brownish pigmentation.

Intramuscular lipomas are benign soft-tissue mesenchymal tumors which rarely occur in the region of the head. These tumors present as slow-growing, generally painless masses and are easily misdiagnosed initially as epidermal inclusion cysts. We describe a 44-year-old woman who presented with an intramuscular lipoma of the frontalis muscle.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

Congenital hepatic fibrosis is an uncommon disease of children and young adults with two major risks: gastrointestinal hemorrhage caused by portal hypertension, and cholangitis related to bacterial infection of dilated intrahepatic bile ducts. It is characterizeed by stony hard hepatomegaly and portal hypertension with rather well preserved hepatic function and architecture, and frequent association of the renal lesions. We have recently experienced a case of congenital hepatic fibrosis in a 24 year-old Korean male. The chief complaint was hematemesis from esophageal varices. There were marked hepatosplenomegaly, mild pancytopenia and the liver function test was within normal engorgement and dilatation of portal and splenic veins and multiple cysts of both kidneys.

Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.
