In a 36-month period, 23 selected Patients with Acute Cerebral Infarction were studied utilizing Computerized Tomography, Barthel Index in an attempt to correlate Brain Computerized Tomography findings with 1week, 4weeks rehabilitation and evaluate the influences of the size and location of the lesion. The study suggested that the size of the lesion had impact on 4 weeks rehabilitation. There was significant different between the patients with Middle Cerebral Artery Pial Territory Infarction(I.P.B.M.C.A.) lesion and the patients with Lacunar Infarction(L.I.), Striatocapsular Infarction(S.C.I.), Internal Watershed Infarction(I.W.I.) lesion, but there was no significant difference between the patients with L.I. lesion and the patients with S.C.I. lesion and the patients with I.W.I. lesion. The size and location of the lesion should be considered together in predicting the functional outcomes of Acute Cerebral Infarction.

Acute osteomyelitis is usually shown as a localized area of increased activity (hot uptake) in the infectious focus on bone scintigraphy. In our patient, absence of radioactivity (cold lesion) was noted in the distal metaphyseal and diaphyseal regions of his right femur. Initial x-ray was interpreted as normal except for mild soft tissue swelling in the right thigh. The lesion was confirmed as an acute osteomyelitis with subperiosteal abscess on surgery. Staphylococcus aureus was the etiologic organism. We describe a case of acute osteomyelitis in a one-year-old boy shown as a cold lesion on bone scan.

A Morel-Lavallée lesion is a post-traumatic closed degloving soft tissue injury after blunt trauma. Infection and skin necrosis frequently occur if it is not treated properly in the early stages. However, there is no clearly established treatment algorithm. In the acute stage, it is mainly treated with aspiration, simple compression, and incisional drainage. In the chronic stage, sclerotherapy is usually performed. If skin necrosis develops, the necrotic tissue is resected and a skin graft is needed. We describe a case of acute Morel-Lavallée lesion in the buttock region that was treated with limited incisional drainage and negative-pressure wound therapy, and also present a review of the literature.

Patients with symptomatic gastrointestinal stromal tumor (GIST) typically present with gastrointestinal bleeding and abdominal pain. This report presents an unusual case of fundic GIST complicated by gastroduodenal intussusception, manifesting as acute pancreatitis. The patient presented with epigastric pain and pancreatic enzyme elevation; thus, he was diagnosed with acute pancreatitis. Computed tomography showed evidence of pancreatitis and a 4×4.7 cm well-defined hyperdense lesion in the 2nd part of the duodenum, compressing the pancreatic head and pancreatic duct. Esophagogastroduodenoscopy revealed invagination of the gastric folds into the duodenum, causing pyloric canal blockage consistent with gastroduodenal intussusception. Spontaneous reduction of the lesion during endoscopy revealed a 4 cm pedunculated subepithelial mass with central ulceration originating from the gastric fundus. Endoscopic ultrasound demonstrated a heterogeneous hypoechoic lesion originating from the 4th layer of the gastric wall. Laparoscopic-endoscopic intragastric wedge resection of the fundic lesion was subsequently performed, and surgical histology confirmed GIST.

Recently ultrasound and scintigraphic study are most useful modality for diagnosis of scrotal diseases. They are able to determine the nature, anatomic extent of the lesion, and possible to differential diagnosis of the scrotal lesion. The ultrasound and scintigraphic findings were analyses in 59 patients of confirmed scrotal disease at Seoul Red Cross Hospital from June 1986 to Aug. 1989. The results were as follows. 1) Most patients were below the 30 years old age (69.4%), and most prevalent age was $11\sim30$ Yrs. in trauma, $31\sim40$ Yrs. in inflammation, and $51\sim60$ Yrs. in mass lesion of scrotum. 2) The diagnostic accuracy of scrotal disease was 94.9% in ultrasound and 72% in scintigraphic study. The ultrasound study showed high accuracy in all kind of scrotat disease, but scintigraphy showed only high detection rate in inflammatory disease. 3) Scrotal ultrasound is first choice of study for the diagnosis of scrotal lesion, and useful determine the cystic or solid lesion and anatomic extent of disease. However it can't be differentiate the acute epididymitis with acute testicular torsion. 4) Scrotal scintigraphy is useful study for the diagnosis of acute painful scrotal disease, and showed specific findings in acute epididymitis and acute torsion for differential diagnosis. 5) In consideration of age, history and clinical findings of patient, appropriate study will be chosen firstly in ultrasound and scintigraphy, and combined all of findings of these studies will be helpful for the accurate diagnosis and adequate treatment of scrotal disease.

목적: 3시간과 24시간 골신티그라피 영상에서 골전이와 급성 및 치유기 골절을 감별하는데 병변/비병변 방사능 섭취비의 24시간/3시간 비율(24 hour/3 hour radio-uptake ratio: 24/3 RUR)이 유용한지 알아보고자 하였다. 대상 및 방법: 총 63명($26{\sim}81$세, 남자 32명, 여자 31명)외 90개 병변(골 전이 30예, 외상 2개월 이내의 급성 골절 30예, 외상 2개월 이상의 치유기 골절 30예)을 대상으로 하였으며 골신티그라피는 $^{99m}Tc$-MDP 740 MBq를 정맥 주사하고 시간과 24시간 후에 영상을 얻었다. 각각의 영상에서 병변과, 인접한 정상 부위의 방사능 섭취비를 측정하여 24시간/3시간 비율(24/3 RUR: [lesion/non-lesion RUR at 24 hour]/[lesion/nonlesion RUR at 3 hour])을 구하여 세 질환을 감별하는데 의의가 있는 지를 분석하였다. 결과: 24/3 RUR의 평균치는 골전이 $1.22{\pm}0.18$, 급성 골절 $1.25{\pm}0.14$, 치유기 골절 $0.99{\pm}0.15$였으며 골 전이와 급성 골절의 24/3 RUR은 유의한 차이가 없었고 골 전이와 치유기 골절, 그리고 급성 골절과 치유기 골절간에는 유의한 차이가 있었다(p<0.001). 24/3 RUR 기준점을 1.0 이상인 경우 골 전이로 진단할 때 민감도는 100% (30/30)였고, 골 전이를 급성 골절로부터 구분하는 소견으로서 특이도는 0% (0/30), 골 전이를 치유기 골절로부터 구분하는 소견으로서 특이도는 47% (14/30)였다. 또한 기준점을 1.2로 설정했을 때는 골전이로 진단하는 소견으로서 민감도 53% (16/30), 골 전이를 급성골절로부터 구분하는 소견으로서 특이도 37% (l1/30), 골 전이를 치유기 골절로부터 구분하는 소견으로서 특이도 100% (30/30)였다. 결론: 24/3 RUR은 골 전이와 치유기 골절을 감별하는데 유용했으나 골 전이와 급성 골절의 감별에는 도움이 되지 않았다. 24/3 RUR이 1.0 미만인 경우는 치유기 골절을, 1.2 이상인 경우는 골 전이나 급성 골절을 시사하는 소견으로 생각된다.

In acute pancreatitis group, all the dogs are showed increase of amylase and lipase after the 1st day of surgery, and amylase and lipase activity were significantly more increased than those of control group. The methemalbumin was increased significantly after the 2nd day of surgery in the acute pancreatitis group. In pancreatitis group, ultrasonographic findings included thickened duodenal wall and poorly circumscribed hyperechoic lesion of pancreatic mass after the 2nd day of surgery. And the lesion was exacerbated until the 4th day and reduced after the 6th day of surgery. To identify the lesion of pancreas, it is considered that transverse view is more useful Than sagittal view. Gross findings showed increase of pancreatic parenchymal consistency, surface nodule, and extensive pancreatic necrosis. Necrosis of peripancreatic fat tissue was also a prominent feature. The microscopic appearance of the pancreas was characterized by pancreatic acinar cell necrosis, hemorrhage, infiltration of the inflammatory cell and fat necrosis and saponification were also observed.

급성 허혈성 뇌경색 환자에서 Deconvolution 관류 전산화 단층촬영(computed tomography, CT)의 뇌혈류용적(cerebral blood volume, CBV), 뇌혈류(cerebral blood flow, CBF) 그리고 평균 조영제 통과 시간(mean transit time, MTT) 지도를 확산 강조(Diffusion weighted) MRI과 비교하여 그 유용성을 알아보고자 하였다. 뇌관류 CT와 확산강조 자기공명영상(diffusion weighted MR imaging, DWMRI)을 시행한 급성뇌경색 환자를 대상으로 Deconvolution 기법으로 획득한 CBV, CBF, MTT 지도에서 병변의 면적과 DWMRI의 병변의 면적을 비교 측정하여 일치도를 알아보았다. 또한, 병변 부위와 정상측 대칭부위의 MTT시간을 측정하여 차이를 알아보았다. 본 연구의 모든 예에서 CBV, CBF, 그리고 MTT 세 지도 모두 관류 결손을 인지할 수 있었고, 관류 결손이 인지되는 부위에서 MTT 시간의 현저한 지연이 있었다. 뿐만 아니라, MTT 지도의 결손부위 면적은 DWMRI 보다 크게 나타나 허혈성 패넘브라를 추측할 수 있었다. 결론적으로 Deconvolution 관류 CT의 지도를 이용하면 뇌경색의 조기진단뿐만 아니라 허혈 중심부, 그리고 허혈성 페넘브라를 예측할 수 있어 DWMRI에 비해 관류결손 부위의 혈류 역학적 상태의 평가나 효과적인 치료계획을 세우는데 보다 유용할 것으로 생각된다.

Vestibular evoked myogenic potentials (VEMP) have been known to useful in documenting abnormality in patients with various vestibular disorders but the studies of VEMP in stroke patients are rare. We recorded VEMP in 17 consecutive patients with acute ischemic stroke in the brainstem lesions. All patients underwent magnetic resonance imaging and we compare VEMP results with the lesion documented by brain imaging. VEMP were defined to be abnormal when they were very asymmetrical (one is 2 times of more as large as the other), or absent in one side. VEMP abnormalities were found in 71%(12/17) of acute infarction patients with brainstem lesions. Most abnormalities found in the ipsilateral side of the lesion(9/12) but abnormalities in contralateral side of lesion were found in 25%(3/12) of patients.VEMP would be considered a useful complementary neurophysiological tool for the evaluation of brainstem dysfunction in acute stroke patients.

Objectives: This study reports a clinical case that showed improvement in the symptoms of a patient with acute gastric mucosal lesion (AGML) through ultrasound. Methods: A 90-year-old woman with AGML was treated with Korean medicine treatments, including Hyangsapyeongwisan Soft Ext, acupuncture, and moxibustion. The responses before and after treatment were evaluated using ultrasound imaging and the numerical rating scale (NRS). Results: After treatment, ultrasound imaging showed improvement in gastric mucosa thickness, from 1.45 cm to 0.53 cm at the anterior wall and from 1.25 cm to 0.36 cm at the posterior wall. The NRS scores for epigastric pain, nausea, and dizziness all decreased, and the symptoms of diarrhea disappeared. Conclusion: This study suggests that Korean medicine treatment can be a therapeutic option in treating the symptoms of patients with AGML.
