For the last decade, we have witnessed dramatic changes in both diagnostic and therapeutic aspects of acute aortic syndrome (AAS). With recent advances of various noninvasive aortic pathology imaging modalities, aortic intramural hematoma (AIH), a variant form of classic aortic dissection (AD), has emerged as an increasingly recognized and potentially fatal AAS entity. As the natural course of AD and AIH, especially with medical treatment, has been reported quite different, there has been a suggestion of applying different treatment strategies based not only on the affected sites of the aorta but also the different AAS entities, which is still in debate. Endovascular stent-graft placement is a revolutionary change in the treatment of various aortic pathologies including AAS. In the next decade, dramatic changes in clinical practice and outcome for patients with AAS are expected using new diagnostic information to select the best treatment option for individual patients.

Organizing hematomas are rare benign tumors and appear as masses that are composed of neovascularization with organizing fibrotic tissue in a hematoma. Although histologically benign, this condition may be clinically progressive. Radiological findings can range from a benign appearance to a more aggressive process, including bony erosion. Organizing hematoma of the maxillary sinus is a rare clinical disease. To our knowledge, only a few cases have previously been published, and most were without bleeding history and disorders. Until now, all of the reports about this lesion have discussed the clinical course, and no previous report has closely considered pathologic findings and pathogenesis. We report three cases of organizing hematoma of the maxillary sinus presenting with an enlarging maxillary sinus mass.

Traumatic intracranial lesion has been one of the most frequent and serous problem in neurosurgical pathology. CT made it possible to get prompt diagnosis and surgical intervention of intracranial lesions by its safety, fastiness and accuracy. Computed tomographic scan was carried out on 1309 cases at Soonchunhyang Chunan Hospitalfor 15 months from Oct. 1983 to Dec. 1984. We have reviewed the computed tomographic scans of 264 patients whichshowed traumatic intracranial lesion. The results were as follows: 1. Head trauma was the most frequentlydiagnosed disase using computed tomographic scans(57.8%), and among 264 cases the most frequent mode of injury wastraffic accident (73.9%). 2. Skull fracture was accompained in frequency of 69.7% and it was detected in CT in38.6%: depression fractue was more easily detected in 81%. 3. Countercoup lesion(9.5%) was usually accompained with temporal and occipital fracture, and it appeared in lower incidence among pediatric group. 4. Intracranial lesions of all 264 cases were generalized cerebral swelling(24.6%), subdural hematoma(22.3%), epiduralhematoma(20.8%), intracerebral hematoma(6.1%), and subarachnoid hemorrhage(3.0%). 5. The shape of hematoma wasusually biconvex(92.7%) in acute epidural hematoma and cresentic(100%) in acute subdural hematoma, but the morechronic the cases became, they showed planoconvex and biconvex shapes. 6. Extra-axial hematoma was getting decreased in density as time gone by. 7. Hematoma density was not in direct proportion to serum hemoglobin levelas single factor.

Otohematoma is a fairly common disease in otolaryngologic clinics. Many physicans have been challanged with various method of management on auricular hematoma. The initial treatment usually involves simple aspiration and a compression bandage. But most of these treatments are recurrent problems and eventually become the cauliflower ear. A treatment involves a total excision of the newly formed fibroneocartilaginous layer. If hematoma persists, perichondrium becomes irregular by thickned fibroneocartilage formation. We treated 11 patients with otoplasty to remove fibroneocartilage under local anesthesia. We found that the perichondrium formed severe fibroneocarilage and organization after 2 weeks. We studied the sequence of pathological changes that occurs after injury.

PURPOSE: We analysed the clinical data to compare the usefulness of ultrasound guided vacuum-assisted Mammotome biopsy between 8G and 11G probes. METHODS: 108 cases in this study underwent an ultrasound- guided minimally invasive excisional breast biopsy through small incision. Removal of the breast lesions was accomplished Mammotome biopsy with 8G or 11G probes. RESULTS: The 108 lesions was excised. Mean size of the lesions were 10.7 mm in 8G and 9 mm in 11G. 105 lesions (95%) had benign pathology, three lesions (2.8%) were malignant, and two lesions (1.9%) had atypical ductal hyperplasia. As procedural complications, hematoma was 23/58 (39.7%) in 8G and 10/50 (20%) in 11G, and ecchymosis was 33/58 (55%) in 8G and 11/50 (22%) in 11G. But there was no major complications which need hospitalization and surgical intervention. CONCLUSION: Breast biopsy using Mammotome with 8G probe is as safe as 11G and effective technique.

The author examined 43 patients with various ophthalmic problems by using E.M.I. scanner 5005/7 from Oct. 77 to Sep. 78. The results which were analized by picture and pathology were obtained as follows; 1) The greaest number of cases were complaints of unilateral and bilateral proptosis. Eleven intraorbital tumors and one mucocele were detected in proptosis cases. 2) Among intraorbital tumors, pseudotumor was most frequently observed. 3) Intraocular tumors were found most frequently at superotemporal and inferotemporal area in the orbit. 4) An increase in absorption coefficient was observed after the use of contrast medium infusion in the case of tumors. On the other hand, no enhancement effect was shown in all cases of mucocele and intracranial hematomas. C.T. is a markedly useful examination, not only to investigate intraorbital space occupying lesions, but also to detect abnormalities of neuro-ophthalmological patients.

STUDY DESIGN: Retrospective case–control study PURPOSE: To clarify the prevalence and risk factors for spinal subdural lesions (SSDLs) following lumbar spine surgery. OVERVIEW OF LITERATURE: Because SSDLs, including arachnoid cyst and subdural hematoma, that develop following spinal surgery are seldom symptomatic and require reoperation, there are few reports on these pathologies. No study has addressed the prevalence and risk factors for SSDLs following lumbar spine surgery. METHODS: We conducted a retrospective analysis of the magnetic resonance (MR) images and medical records of 410 patients who underwent lumbar decompression surgery with or without instrumented fusion for degenerative disorders. SSDLs were classified into three grades: grade 0, no obvious lesion; grade 1, cystic lesion; and grade 2, lesions other than a cyst. Grading was based on the examination of preoperative and postoperative MR images. The prevalence of SSDLs per grade was calculated and risk factors were evaluated using multivariate logistic regression analysis. RESULTS: Postoperative SSDLs were identified in 123 patients (30.0%), with 50 (12.2%) and 73 (17.8%) patients being classified with grade 1 and 2 SSDLs, respectively. Among these, one patient was symptomatic, requiring hematoma evacuation because of the development of incomplete paraplegia. Bilateral partial laminectomy was a significantly independent risk factor for SSDLs (odds ratio, 1.52; 95% confidence interval, 1.20–1.92; p<0.001). In contrast, a unilateral partial laminectomy was a protective factor (odds ratio, 0.11; 95% confidence interval, 0.03–0.46; p=0.002). CONCLUSIONS: The prevalence rate of grade 1 SSDLs was 30%, with no associated clinical symptoms observed in all but one patient. Bilateral partial laminectomy increases the risk for SSDLs, whereas unilateral partial laminectomy is a protective factor.

The damage degree of neurons in perilesion at different time points was observed in order to explore the optimal operation occasion. Piglet lobar hematomas were produced by pressure-controlled infusions of 2.5 mL autonomous blood into the right frontal hemispheric white matter over 15 min, and the metabolic changes were ambulatorily detected with MRS at 3rd, 12th, 24th and 48th h after hematoma induction. Brain tissues of perihematoma were also obtained at different time points. The transcription level of Bax gene was detected by in situ hybridization and apoptosis by TUNEL technique, and the pathologic change of neurons was observed under an electron microscope. The results showed that the number of Bax positive cells reached the peak at 24 h (79.00 +/- 4.243/5 fields). There was no significant difference in A values between 3 h and 6 h, 12 h (P > 0.05), but there significant difference between 24 h and 3 h, 6 h, 12 h (P < 0.05). The number of apoptotic cells reached the peak at 24 h (P < 0.001), and there was no significant difference between 3 h and 6 h (P = 0.999). The area of the apoptotic cells showed no significant difference between 3 h and 6 h or among 3 h, 6 h and 6 h (P > 0.05). Lac peak mainly occurred at 24 h and 48 h, while on the healthy side, no Lac peak was detectable. The ratio of NAA/Cr presented a descent tendency, but there was no significant difference among the groups before 12 h (P > 0.05), there was very significant difference between 3, 6 and 24, 48 h (P < 0.01). Under electronic microscopy, the neuronal damage surrounding hematoma in 3 to 6 h was milder than in 24 h to 48 h. It was concluded that the secondary apoptosis, damage and metabolic disturbance of the neurons surrounding hematoma was milder in 3-6 h in acute intracerebral hemorrhage, while obviously aggravated in 24-48 h. An effective intervention is needed to reduce secondary damage as soon as possible.
