T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.

Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

Chordoma arising from the notochordal remnants is a rare primary bone tumor in the cervicosacral region and is even more unusual in the thoracic region. The authors experienced a case of thoracic chordoma and report its CT and MR findings.

Plantar fibromatosis, otherwise known as Dupuytrens disease of the foot, is a relatively uncommon benign lesion. It is characterized by the replacement of elements of the plantar aponeurosis with fibrous tissue, which then slowly invades the skin and the deep structures. Generally an asymptomatic lesion, plantarfibrosis may occasionally cause foot pain. We recently experienced a case of painful plantar fibromatosis. On which a wide surgical excision was done. A one year postoperatively, follow-up examination revealed neither recurrence nor walking disability.

The purpose of this study is to demonstrate the effectiveness of arthrocopic treatment for the avulsion fracture of intercondylar eminence of the tibia and of the technique of arthroscopically assisted reduction and fixation through pull-out suture method. Between January 1995 and May 1997, three patients were underwent arthroscopic reduction and suture fixation for type 0 of avulsion fracture of intercondylar eminence of tibia and were followed up. The result of two patients were graded as normal and one as nearly normal by the criteria of the International Knee Documentation Committee(IKDC) rating scale. The advantages of this technique include no retained hardware and ability to treat comminuted fracture(type g ). We describe technique of arthroscopic reduction and suture fixasion for displaced avulsion fractures, including those with comminution of intercondylar eminence of tibia.

We studied the intradural variations of spinal nerve rootlets in 100 cases of Korean adults. The results of the study are as follows ; 1. The incidence of intrasegmental variations (abberrant rootlets) is high in cervical segments and decreased toward lumbosacral segments. The incidence is higher in posterior rootlets than anterior, except cervical sesments. 2. The incidence of intersegmental variations is higher in posterior rootlets than anterior, and generally high in cervical and lumbar segments. 3. We divide the intersegmental variations into supernumerary rootlets, dividing rootlets, and anastomosing rootlets, and among them the incidence of anastomosing rootlets is higher. We divide the anastomosing rootlets into parallel anastomosing rootlets, uniting anastomosing rootlets, and rearrangement anastomosing rootlets. 4. The anterior to posterior anastomosing of spinal nerve rootlet is present in 4 of cases studied.

Single breath-hold gradient echo images with Small Tip. Angle Gradient Echo(STAGE) were evaluated in the study of liver in 16 patients(4 normal liver, 5 hepatoma, 5 cholangiocarcinoma, 1 hemangioma, 1 cavernous transformation of portal vein). We obtained one slice of gradient echo during single breath-hold at the level of pathology defined on conventional spin echo inage. Single breath-hold gradient echo images were compared with spin echo images for image quality and artifacts. Single breath-hold gradient image showed improved resolution of vascular detail and excellent contrast between lesion and adjacent normal liver in hepatoma. Cholangiocarcinoma showed decreased contrast between lesion and biliary trees but improved contrast between lesion and blood vessel. Cavernous transformation of porta vein was noted as tortuous vessel of high signal intensity. Single breath-hold gradient echo scan increased vascular artifact, but decreased respiratory artifact leading to improved image quality. Single breath-hold technique can reduce can reduce imaging time and improve image quality and may be used as complementary method to the spin echo scan.
