Breast thermography produces a picture of the heat emitted from the surface of the breast. And abnormal temperature over the breast has been suggested as an indicator of malignancy. The mechanisms for the heat production at the area of the skin over the breast are suggested hypermetabolism, hypervascularization, and hyperfusion of the affected regions of the breast. The purpose of this study was to evaluate the diagnostic accuracy of breast thermography in breast cancer. One hundred thirty breast cancers and one hundred ten benign breast masses were examined by a digital infrared thermographic system (NEC San-ei, Therm Tracer 6T67) between January 1991 and December 1995. In this study, thermograms were classified as normal (Th-1), equivocal (Th-2), or abnormal (Th-3). Normal thermograms were those with normal symmetric vascularity, equivocal thermograms were those with only heat in the area of mass, and abnormal thermograms were those with heat and increased vascularity in the area of mass. Among the 110 benign breast masses, there were 98 Th-1 cases (89.1%), 2 Th-2 cases (1.8%) and 10 Th-3 cases (9.1%). Among the 130 breast cancers, there were 98 Th-3 cases (75.4%), 20 Th-2 cases (16.2%), and 12 Th-1 cases (9.2%). The sensitivity of the breast thermograms was 90%, the specificity 89.1%, and the diagnostic accuracy 89.6%. A thermal difference(deltaT) of less than 1oC was seen in 10 cases (7.7%) of breast cancer, and a deltaT of more than 1oC was seen in 120 cases (92.3%). Among the latter of a deltaT of more than 3oC was seen in 67 cases(51.4%). The correlation of the breast-cancer tumor size with deltaT was highly significant(p<0.0001). The classification of the thermographic diagnosis was found to be statistically correlated with tumor size (p<0.0001), axillary node status (p<0.001) and nuclear grade (p<0.05), but not with the presence or abscence of estrogen receptor. These results suggest that thermography is useful as a diagnostic tool for breast cancer. And that a deltaT of more than 2oC of on a breast thermogram strongly suqqests a malignancy.

Spontaneous rupture of subcapsular liver hematoma in pregnancy is rare but potential life threatening complication of preeclampsia. We experienced a case of spontaneous rupture of subcapsular hematoma of liver that was treated with conservative method. So, we present the case with a brief review of literatures as first report in Korea.

Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

We report here on a rare case of a ruptured basilar tip aneurysm that was successfully treated with coil embolization in the bilateral cervical internal carotid artery (ICA) occlusions with abnormal vascular networks from the posterior circulation. A 43-year old man with a familial history of moyamoya disease presented with subarachnoid hemorrhage. Digital subtraction angiography demonstrated complete occlusion of the bilateral ICAs at the proximal portion and a ruptured aneurysm at the basilar artery bifurcation. Each meningeal artery supplied the anterior cranial base, but most of both hemispheres were supplied with blood from the basilar artery and the posterior cerebral arteries through a large number of collateral vessels to the ICA bifurcation as well as the anterior cerebral and middle cerebral arteries. The perfusion computed tomography (CT) scans with acetazolamide (ACZ) injection revealed no reduction of cerebral blood flow and normal cerebrovascular reactivity to ACZ. An abdominal CT aortogram showed no other extracranial vessel abnormalities. A ruptured basilar tip aneurysm was successfully treated with coil embolization without complications. Endovascular embolization may be a good treatment option with excellent safety for a ruptured basilar tip aneurysm that accompanies proximal ICA occlusion with vulnerable collateral flow.

OBJECTIVE: The aim of this study was to determine the role of intra-arterial (IA) nimodipine injections for cerebral vasospasm secondary to ruptured subarachnoid hemorrhage (SAH) and to investigate the factors that influence vasodilation and clinical outcomes. METHODS: We enrolled 29 patients who underwent aneurysm clipping for ruptured cerebral aneurysms between 2009 and 2011, and who received IA nimodipine after subsequently presenting with symptomatic vasospasm. The degree of vasodilation shown in angiography was measured, and the correlation between the degree of vasodilation and both the interval from SAH to cerebral vasospasm and the interval from clipping to cerebral vasospasm was determined. The change in blood flow rate after IA injection was assessed by transcranial Doppler ultrasound. Multiple clinical parameters were completed before and after IA nimodipine injection to evaluate any improvements in clinical symptoms. RESULTS: For eight patients, Glasgow Coma Scale (GCS) scores increased by two or more points. The regression analysis demonstrated a positive correlation between the change in GCS scores after IA nimodipine injection and the change in blood vessel diameter (p=0.025). A positive correlation was also observed between the interval from SAH to vasospasm and the change in diameter (p=0.040); and the interval from clipping to vasospasm and the change in diameter (p=0.022). CONCLUSION: IA nimodipine injection for SAH-induced vasospasm led to significant vasodilation in angiography and improvement in clinical symptoms without significant complications. Our findings suggest that IA nimodipine injection should be utilized when intractable vasospasm develops despite rigorous conservative management.

Ossified lipoma or osteolipoma are rarely reported. It is defined as a histologic variant of lipoma that has undergone osseous metaplasia. Osteolipoma presents with a dominant osseous component within a lipoma. We report a case of a histologically confirmed osteolipoma on the nuchal ligament independent of bone. The patient was a 51-year-old female who presented with a 5-year history of a painless, progressively enlarging mass on the posterior neck. Computed tomography and magnetic resonance imaging showed a circumscribed mass compatible with fat between the C2 and C6 spinous processes with a large calcified irregular component. The mass with dual components was totally removed under general anesthesia and no recurrence was observed after 6 months of follow-up. We also reviewed the clinicopathologic features of previously reported osteolipomas in the literature and suggest that although osteolipoma is a rare variant of lipoma, it should be considered in the differential diagnosis when a lipoma of the posterior neck mixed with a bony component is encountered.

OBJECTIVE: The aim of this study was to evaluate effect of pulsed radiofrequency (PRF) neuromodulation of suprascpaular nerve (SSN) in patients with chronic shoulder pain due to adhesive capsulitis and/or rotator cuff tear. METHODS: The study included 11 patients suffering from chronic shoulder pain for at least 6 months who were diagnosed with adhesive capsulitis (n=4), rotator cuff tear (n=5), or adhesive capsulitis+rotator cuff tear (n=2) using shoulder magnetic resonance imaging or extremity ultrasonography. After a favorable response to a diagnostic suprascapular nerve block twice a week (pain improvement >50%), PRF neuromodulation was performed. Shoulder pain and quality of life were assessed using a Visual Analogue Scale (VAS) and the Oxford Shoulder Score (OSS) before the diagnostic block and every month after PRF neuromodulation over a 9-month period. RESULTS: The mean VAS score of 11 patients before PRF was 6.4+/-1.49, and the scores at 6-month and 9 month follow-up were 1.0+/-0.73 and 1.5+/-1.23, respectively. A significant pain reduction (p<0.001) was observed. The mean OSS score of 11 patients before PRF was 22.7+/-8.1, and the scores at 6-month and 9 month follow-up were 41.5+/-6.65 and 41.0+/-6.67, respectively. A significant OSS improvement (p<0.001) was observed. CONCLUSION: PRF neuromodulation of the suprascapular nerve is an effective treatment for chronic shoulder pain, and the effect was sustained over a relatively long period in patients with medically intractable shoulder pain.
