2.Endovascular Treatment of a Large Partially Thrombosed Basilar Tip Aneurysm.
Journal of Korean Neurosurgical Society 2012;51(1):62-65
Despite the remarkable developments in neurosurgical and neuro-interventional procedures, the optimal treatment for large or giant partially thrombosed aneurysms with a mass effect remains controversial. The authors report a case of a partially thrombosed aneurysm with a mass effect, which was successfully treated by stent-assisted coil embolization. A 41-year-old man presented with headache. Brain computed tomography depicted an 18x18 mm sized thrombosed aneurysm in the interpeducular cistern. More than 80% of the aneurysm volume was filled with thrombus and the canalized portion beyond its neck measured 6.8x5.6 mm by diagnostic cerebral angiography. Stent-assisted endovascular coiling was performed on the canalized sac and the aneurysm was completely obliterated. Furthermore, most of the thrombosed aneurysm disappeared in the interpeduncular cistern was clearly visualized follow-up brain magnetic resonance imaging conducted at 21 months. The authors report a case of selective coiling of a large, partially thrombosed basilar tip aneurysm.

We report a rare cause of lung cavities, occurring in a patient with intrapulmonary cystic teratoma. Computed tomography (CT) provided us more detailed informations about the tumor characteristics containing fat and calcification, which could not be distinguished on the plain radiographs. In addition, CTscans clearly demonstrated the dilated anterior segmental bronchus of the left upper lobe entering the posterior aspect of the cavity.

Cardiovascular changes has been reported eating and digestion. Experimental studies showed an early rise in cardiac output during eating which was attributable to an increased heart rate. This changes reverted to baseline valuse at the end of eating. To investigate postprandial cardiac functional change, we studied 20 healthy young men(average age 27 years) nonivasively with BP measurement, electrocardiography and M-mode echocardiohrapy before, 30 minutes and 3 hours after a lunch(600 Kcal). There was no significant changes in mean blood pressure after eating. On echocardiography, diastolic and systolic left ventricular internal dimensions were 4.9+/-0.4 and 3.1+/-0.4cm before meal and 4.9+/-0.4 and 2.9+/-0.3cm 30 minutes after eating. There was an average increase of 9% in cardiac output 30 minutes after meal. Fractional shortening was 36.4+/-6.4% before meal and 40.4+/-6.1(p<0.05) 30 minutes after eating. Ejection fraction changed from 73.5+/-7.9% to 78.2+/-6.3%(p<0.05) at postprandial 30 minutes. Myocardial contractility index assessed by the ratio of systolic BP to end-systolic volume was 4.3+/-1.6mgHg/ml before and 5.3+/-2.2mmHg/ml 30 minutes after eating. Peripheral resistance index as the ratio of mean blood pressure divided by cardiac index changed from 2,536+/-1,120dynesdSdcm-5/m2 to 2,048+/-472dynesdSdcm-5/m2 at postprandial 30 minutes. Electorcardiographic study revealed no changes in ST SE segment, T wave and heart rate after a meal. In conclusion, the increase of cardiac output after a moderate meal in healthy young men was associated with an increase in myocardial contractility and a decrease in peripheral vascular resistance.

Mucinous adenocarcinomas of the anal region constitute only 2% of anal cancer and adenocarcinoma developing in a chronic tuberculous anal fistula is extremely rare. In most cases, its origin is difficult to ascertain because the primary sites have already been destroyed before any diagnosis of malignancy is made. We experienced a case of perianal adcnocarcinoma developing in chronic tuberculous anal fistula, which was treated by abdominoperineal resection with preoperative chemo-irradiation. We reported a case and reviewed the related literatures.

In advent of high-resolutional CT and MRI, it is not so difficult to detect the lumbar synovial cyst, however the unusual disease should be included in the differential diagnosis of cauda equine compression syndromes. The case of a 55-year-old man who had a low back pain and severe radiating pain on both legs showed a retrolisthesis at L3-4 and L4-5 and epidural enhancing mass just around L4-5 facet joint on MRI. Microscopically a lining of synovial tissue was demonstrated. After surgery of the total resection of synovial cyst and stabilization, the patient's presenting symptoms were improved.

The author performed radiosurgery with linear accelerator(LINAC) on two patients who were unable to receive surgical treatment. A 75-year-old-male patient(case 1) whose main complaints were gait disturbance and headache had undergone total resection of cerebellar hemangioblastoma five years before the admission and the lesion recurred. Because the patient's general condition was poor, radiosurgery with LINAC was performed and at 1 month after the radiosurgery, obstructive hydrocephalus developed, and ventriculoperitoneal shunt was done. After 11 months, follow-up brain magnetic resonance image findings showed the decrease of the size of the tumor, and the patient's consciousness returned to alertness. He could also walk using a cane. A 28-year-old male paient(case 2) whose main complaints were vertigo, ataxia refused to receive surgical resection due to his religious beliefs, and radiosurgery was performed, after cyst aspiration with ommaya reservoir insertion as an alternative. Eighteen months later, the tumor size has decreased and there were no radiosurgical complications. The patient has been followed-up at the outpatient without any notable symptoms. Through these two cases, the authors experienced tumor control by LINAC radiosurgery when surgical treatment is not acceptable. Radiosurgery seems safe and effective in the treatment of hemangioblastoma, but there is the need for further evaluation.

We examined the fibronectin(FN) secretion by cultured trabecular meshwork(TM) cells from a normal human eye by indirect immunofluorescent technique using mouse anti-human FN monoclonal antibody and FITC-conjugated goat anti-mouse IgG. To localize FN on frozen sections of normal TM which were obtained from 7 enucleated eyes owing to traumatic eyeball rupture, the same indirect immunofluorescent method was used. Immunoelectron microscopy was applied to demonstrate the distribution pattern of FN in the normal TM of 2 human eyes using an avidin-biotin-peroxidase complex method. In tissue culture of TM, TM cell walls and extracellular matrices showed an intense staining with antibody to FN. Indirect immunofluorescent staining of FN on frozen sections of TM showed strong positive reactions in the subendothelial region. There was no reaction in the central core of the trabecular beam. Immunoelectron microscopy revealed the reaction products to FN in the areas lining the trabecular endothelial cells.

Malignant lymphoma in the eye and its adnexa can occur rarely as a primary tumor as well as a part of disseminated malignant lymphoma. A case of bilateral conjunctival involvement in the disseminated lymphocytic type malignant lymphoma in a 60 year-old male patient is reported because of its rarity and review of the literature is made. Other organ involvement includes cervical, axillary, hilar and inguinal lymphnodes, liver, spleen and bone marrow.
