Intravascular papillary endothelial hyperplasia (Masson's hemangioma) is a disease characterized by exuberant endothelial proliferation within the lumen of medium-sized veins. In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis. The lesion has a propensity to occur in the head, neck, fingers, and trunk. Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date. The authors have experienced intravascular papillary endothelial hyperplasia of the liver in a 69-yr-old woman, and report the case with a review of the literature.

Though leiomyosarcoma usually occurs in the gastrointestinal tract and uterus, it rarely occurs in the wall of large veins and arteries. We present a case of primary leiomyosarcoma arising in the great saphenous vein of the left inner thigh and spreading for some extent along the vein in a 54 year old female. Diagnosis was confirmed by desmin stain and electron microscopy. Postoperative course was fine. This is the first report of this in Korean literature.

This case presents a 34-year-old man who had a huge parasagittal meningioma. Initial treatment consisted of preoperative external carotid artery embolization and partial tumor resection. During the resection, we found that the tumor invaded the adjacent calvarium, and due to massive hemorrhage, total removal of the tumor was impossible. The patient was treated with intraoperative radiation therapy (IORT) (25 Gy via 16 MeV) as an adjunctive therapy. Eight months after IORT, we were able to remove the tumor completely without surgical difficulties. IORT can be considered an useful adjunctive therapy for the superficially located, huge, and highly vascular meningioma.

Primary cardiac tumors are extremely rare and can originate within the heart or be the result of tumor spread from other sites. We report a female patient with a pulmonary vein tumor extending into the left atrium that had a suspicious primary malignant origin with a sacral metastatic carcinoma. The patient was admitted complaining of pain in her buttock area as a result of a sacral tumor. It was believed that the sacral tumor was a metastasis from the imaging study and clinical manifestation. The primary malignant origin was evaluated. The chest CT showed a left atrium thrombus-like lesion without a pulmonary abnormality. After a transesophageal echocardiogram, the patient was diagnosed with a pulmonary vein tumor extending to the left atrium. The patient was given palliative radiotherapy for the sacral pain. Initially, the clinical impression was a metastatic sacral tumor with a thromboembolism of the left atrium. However, this patient was finally diagnosed with a pulmonary vein tumor with a left atrium extension by a transesophageal echocardiogram.

OBJECTIVETo explore the sonographic characteristics of intraveous leiomyomatosis (IVL) with intracardiac extension and improve its diagnosis.

METHODSThe clinical and sonographic data of 13 female patients with pathologically confirmed IVL with intracardiac extension who were treated in our hospital between 2002 and 2012 were retrospectively analyzed. These patients aged 44 years old (range: 38-49 years), and 10 of them were first-episode patients and the remaining 3 were recurrent patients. Eight patients had a history of hysterectomy for leiomyoma.

RESULTSThe first-episode symptoms included exertional chest tightness and shortness of breath (n=5), abdominal distention and edema of low extermity (n=4), exertional palpitation of cardiac origin (n=3), and menorrhagia (n=1). Ultrasonography showed that all patients had isoechoic or hypoechoic tumors extended through the inferior vena cava into right heart chambers (62% in right atrium alone and 38% in right ventricle and atrium). Nine masses in right heart chamber (69.2%) were oval and 4 (30.8%) were serpentine, which were all with well-demarcated borders and most (80%) with heteroechogenic texture. Ten patients had hypoechoic or mixed echoic tumors in pelvic cavity or uterus, and 6 of them had abundant blood flow.

CONCLUSIONSIVL with intracardiac extension has certain sonographic characteristics. Ultrasonography is a valuable tool in the diagnosis of IVL with intracardiac extension.
