Since the placenta is an organ composed of blood vessels, it is not surprising that its primary neoplasm would be a vascular tumor. Placental tumors, primary or secondary, have been known to interfere with placental function. Chorioangioma(primary tumor of the placenta), which is the most common of them, occurs with an incidence for clinically significant ranges from 1~2.8:10000 births. These tumors are benign and are not usually associated with clinical sequelae unless they are larger than 5cm in long diameter. About one third of the large chorioangiomas may be associated with the maternal and fetal complications. For diagnosis of these lesions, the ultrasonography was used. If the chorioangioma is suspected, color doppler study is informative to confirm the presence of the vascular channels. We reviewed ultrasonograms and clinical records of seven patients who had been diagnosed as placental chrioangioma. The appropriate diagnostic tests and treatment can then be initiated in order to prolong gestation and decrease fetal mortality and morbidity.

Isolated chloromas(granulocytic sarcomas) are rare tumors. Chloromas are masses composed of immature granulocytic cells. Granulocytic sarcoma occurs primarily in patients with acute myelogenous leukemia as well as in patients with other myeloproliferative disorders, but rarely in patients with acute lymphoblastic leukemia(ALL). We now describe one patient affected by ALL with isolated granulocytic sarcoma as initial CNS relapses. These unusual clinical manifestation and radiological finding in acute lymphoblastic leukemia should be considered as recurrence of leukemia. Early detection and antileukemic treatment of granulocytic sarcoma are necessarily important for favorable prognosis.

The authors report a rare case of multiple schwannomas associated with intracranial, intraspinal and peripheral involvements. A 63-year-old woman presented with a seven-year history of palpable lumps on both sides of the supraclavicular area and hearing impairment in both ears. On physical examination, no skin manifestations were evident. Facial sensory change, deafness in the left ear and decreased gag reflex were revealed by neurological examination. Magnetic resonance imaging revealed multiple lesions of the trigeminal nerves, acoustic nerves, lower cranial nerves, spinal accessory nerve, brachial plexuses, and spinal nerves. Pathological examination of tumors from the bilateral brachial plexuses, the spinal nerve in the T8 spinal position and the neck mass revealed benign schwannomas.

We reviewed the medical records of the 65 patients with stage 1 macular holes and evaluated the effect of prophylactic vitrectomy (34 patients)compared with observation only (31 patients).Mean follow up period was 38.2 and 27.7 months, respectively.88.3%of the patients of the vitrectomy group, and 87.1%of the patients of the observation group showed improved or same visual acuity.Postoperative complications were noted in 35.3%of the vitrectomy group, and lens nuclear sclerosis was the most frequent postoperative complication.Progression of stage 1 macular holes to the higher stage hole was noted in 5.9%of vitrectomy group, and 9.6%of the observation group.There was no statistical significance between two groups.And the prognosis of stage 1 macular hole is thought to be favorable.

PURPOSE: We wanted to evaluate the clinical utility of performing bilateral whole breast US as a subsequent diagnostic method along with mammography in asymptomatic women. MATERIALS AND METHODS: From May 2002 to Dec 2004, we conducted 3998 examinations on 3638 patients with negative findings on the clinical examination and negative mammographic results, and those breast tissues having a BI-RADS category 2, 3, or 4 density were further evaluated by performing bilateral whole breast US. The patients' age distribution ranged from 24 to 66 years (mean age: 43.6 yrs). The abnormalities were compared with core or vacuum assisted core biopsy, operations, and follow up US. For the normal cases, we used the clinical notes and the statistical data from the Korean Central Cancer Registry. RESULTS: For 3998 examinations of 3638 women who were examined with bilateral whole breast US, pathologic confirmations were available for 433 patients and follow-up data were available for 35 patients. The sensitivity, specificity, the positive predictive value and the cancer detection rate of using additional whole breast US were 50, 92.6, 0.6 and 0.5, respectively. The two cancers that were detected only on US were minimal breast cancer. CONCLUSION: Although all the breast cancers that were detected only on US were minimal breast cancers, performing bilateral whole breast US revealed a low cancer detection rate and a high false positive. Therefore, further studies will be needed to investigate the role of US as a screening tool.

The authors report a 39-year-old male suffering pulsatile tinnitus of the left ear with dural arteriovenous malformation of the jugular bulb. There was a venous hypertension due to partial occlusion of the internal jugular vein and sigmoid sinus and venous drainage to the contralateral sinuses. Superselective embolization of these feeding arteries was successfully performed using 25% mixture of histoacryl and lipiodol. After embolization, his complaints of pulsatile tinnitus and buzzing noise behind his left ear disappeared. We present a case of dural arteriovenous malformation involving the jugular bulb, which completely disappeared after transarterial embolization with liquid adhesive.
