Renal infarction usually occurs in patients with atrial fibrillation, valvular heart disease, trauma, renal artery stenosis, atherosclerosis and coagulopathy. However it may occur rarely in patients without such underlying disease. We report on 3 patients who developed renal infarction and had no underlying disease. In two cases, renal artery thrombosis occured. And in the other case, renal artery dissection occured. All patients of the renal infarction experienced severe flank pain. And increased serum LDH, ALT and ALP was noted. The differential diagnosis of renal artery dissection and renal artery thrombosis was established by renal artery angiography. In two patients with renal artery thrombosis, anticoagulation therapy was performed. In the other patient with renal artery dissection, only conservative therapy was performed. All 3 patients of renal infarction preserved normal renal function. but developed hypertension. Two patients were given anti-hypertensive agents. In the other patient, hypertension was normalized spontaneously.

STUDY DESIGN: Radiological investigation to study the morphologic difference of posterior facet joint in spondylolysis and isthmic spondylolisthesis. OBJECTIVES: To study the correlation of the clinical differences between the one with spondylolysis and another with isthmic spondylolisthesis with morphological analysis of posterior facets of lumbar spine in low back pain, anterior displacement and segmental instability. SUMMARY OF LITERATURE REVEIW: There are many studies for the lumbar facet in back pain, disc degeneration, degenerative spondylolisthesis. However, little is known about the correlation of facet joint between the spondylolysis and isthmic spondylolisthesis. METHODS: This study is done with 27 specimens which contain posterior facet and lamina from 25 patients due to spondylolysis or isthmic spondylolisthesis. We took the computed tomograms in each specimen and obtained the areas and angles of posterior facets of lumbar spine. RESULTS: The group with spondylolysis has mean area(Rt/Lt) of 158.4/159.3mnfand angle(Rt/Lt) of 49.8u/54.0u. The group with isthmic spondylolisthesis has mean area(Rt/Lt) of 172.3/189.6mnfand angle(Rt/Lt) of 44.3u/44.8u. The group with segmental instability has mean(Rt/Lt) area of 155.9/161.8mnfand angle of 48.1u/50.4u. The group without instability has mean area(Rt/Lt) of 173.4/185.2mnfand angle(Rt/Lt) of 46.2u/48.5u. CONCLUSION: There are no significant differences between the morphologic difference of facets with back pain and without back pain. The group with isthmic spondylolisthesis has greater mean area and less mean angle of facet than the group with spondylolysis, but, there are no statistical significant differences(p>0.05). There are no significant morphologic differences of facet between the group with segmental instability and without segmental instability.

Pulmonary blastoma is a primary lung tumor consisting of a mixture of immature embryonal-like mensenchymal and epithelial components and in some areas resemble embryonal lung tissue of up to 3-4 months gestational age. The tumor was first described in 1945 by Barrett and Barnard and again in 1952 by Barmard, who named it an embryoma of the lung which resembled fetal lung histologically, with glandular structures lined by non-ciliated epithelium and a surrounding stroma resembling mesenchyme. In 1961 Spencer renamed them Pulmonary blastoma as he believed they represented neoplasms similar in pathogenesis to nephroblastoma. The prognosis of these tumors is poor, and the clinical course is not readily predicted from histological appearance. Untill now, more than one hundred cases have been reported in the literature in the word and there is no report in Korea. We report a case of biphasic pulmonary blastoma, which ruptured spontaneously, in a 31-year-old young man who was presented as sharp pain under the right subscapular area.
