Alveolar soft-part sarcoma is a rare soft tissue sarcoma of young adults with unknown histogenesis, and the organ most frequently involved in metastasis is the lung. We report the CT findings of three patients of pulmonary metastases of alveolar soft-part sarcoma, which manifested as clearly enhanced pulmonary nodules or masses. On enhanced scans, some of the masses were seen to contain dilated and tortuous intratumoral vessels.

The giant serpentine aneurysm(GSA) is an entity defined on radiological and pathological grounds as a giant, partially thrombosed aneurysm containing tortuous vascular channel which usually supplies the territory distal to the aneurysm. GSAs belong to the subgroup of giant aneurysms, however, they are distinct from giant saccular and fusiform aneurysms. We present a case of giant serpentine aneurysm of a middle cerebral artery treated with wrapping under the extracorporeal circulation and hypothermia.

Hemangioma is the most common soft tissue tumor in the body. Though it may occur anywhere in the body, hemangioma of the uterus is a very rare tumor. Hemangioma is almost asymptomatic, but it is sometimes clinically important because it can cause massive hemorrhage and this is a life-threatening condition. We report here on the magnetic resonance imaging and pathologic findings of cavernous hemangioma of the uterus in a 32-year-woman with menorrhagia.

We report here on a case of a 34-year-old man with unruptured aneurysm of the left sinus of Valsalva, and he presented with acute coronary syndrome due to the putative dynamic compression of both the left main coronary artery and the left circumflex coronary artery. The cardiac multislice computed tomography scanning and coronary angiogram revealed the compression of the two coronary arteries by the aneurysm of the left sinus of Valsalva. Aneurysmectomy was performed for surgical repair. After the surgery, the patient stayed asymptomatic during the 6-months of follow-up.

BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor and nonmotor symptoms such as cognitive impairment and neuropsychiatric symptoms. The aim of this study was to investigate the spectrum of neuropsychiatric symptoms in PD according to cognitive function. METHODS: One hundred twenty seven patients with PD were consecutively recruited. They had undergone an intensive interview with a neurologist and the Seoul Neuropsychological Screening Battery-dementia version, and were divided into three groups: 27 patients in PD with normal cognition (PDNC), 57 in PD with mild cognitive impairment (PDMCI), and 43 in PD with Dementia (PDD). Forty five healthy controls without memory complaints were also recruited. The caregivers of all participants administered the Caregiver-Administered Neuropsychiatric Inventory (CGA-NPI). RESULTS: There were significant differences in the CGA-NPI score (22.8+/-20.9 vs. 6.4+/-10.1 vs. 1.7+/-3.9 vs. 1.0+/-1.6, p<0.001), and the prevalence of neuropsychiatric symptoms (100% vs. 64.9% vs. 37.0% vs. 44.4%, p<0.001) among PDD, PDMCI, PDNC and control groups. Depression was the most common symptom (43.3%), followed by anxiety (31.5%), apathy (26.8%), and night-time behavior (26.8%) in all PD patients. Delusion, hallucination, and aberrant motor behavior were observed frequently in PDD, but were rare in PDMCI. CONCLUSIONS: Depression was the most common neuropsychiatric symptom in PD. The presence of delusion, hallucination, or aberrant motor behavior may suggest PDD. The neuropsychiatric symptoms were not prevalent in PD with normal cognition.

Gastric leiomyoblastoma is an uncommon intramural tumor, Its been regarded as a tumor of smooth muscle origin by its histological and electronmicroscopic characteristics. However, recent immunohistochemical staining techniques have shown that tumors diagnosed as leiomyoblastoma may have different tumor origins. We report a case of multiple leiomyoblastoma of the stomach thought to be of unknown derivation by Immunohistochemical study.

OBJECTIVE: Compared with other neural structures, optic apparatus are particularly sensitive to radiation. If tumors are adjacent to or in contact with optic apparatus, a number of limitations need to be addressed for planning radiosurgery. To avoid radiation induced optic neuropathy, we treated these lesions with fractionated stereotactic radiosurgery (FSRS). This study is undertaken to assess the efficacy of FSRS for sella and parasella tumors adjacent to or in contact with optic apparatus. METHODS: We treated 19 sellar region tumors located adjacent to or in contact with optic apparatus with fractionated stereotactic radiosurgery using the Novalis system. Seventeen patients who could be followed were included in this study. They consisted of 8 pituitary adenomas, 4 optic gliomas, 3 meningiomas, 2 craniopharyngiomas. The mean tumor volume was 16.1cc(range 1-61.1). When planning FSRS, the prescribed fractionation dose to optic apparatus below 200cGy. Follow up examinations consisted of neurological, neuroradiological, and neuroopthalmological evaluations. RESULTS: Follow-up ranged from 2 to 34 months(mean 15 months). Serial magnetic resonance imaging revealed no increase in volume of tumor in all 17 patients. No patients had radiation induced optic neuropathy. CONCLUSION: Fractionated stereotactic radiosurgery is proper innovative treatment modality for sella or parasella tumors adjacent to or in contact with optic apparatus to avoid radiation induced optic neuropathy. We need further follow-up and clinical experiences.

High flow priapism is a prolonged, non-painful penile erection unrelated to sexual stimulation after penile or perineal trauma. We report a case of high-flow priapism treated successfully with superselective embolization. An 8-year-old boy presented to our hospital 9 days after having been struck in the perineum during a bicycle accident. After the injury, the patient suffered a painless prolonged erection. High flow priapism was diagnosed by cavernosal blood gas analysis and penile duplex doppler ultrasonography. We identified the position of the fistula and pseudoaneurysm with angiography and embolized the lesions super-selectively with an autologous blood clot, gel foam, and a microcoil, bilaterally. After 2 superselective embolizations, the patient had detumescence. This case shows that bilateral arterio-cavernosal fistulas can be successfully treated with superselective arterial embolization.
