Percutaneous biopsy is the most frequent interventional radiographic procedure. Its increased use is relatedto new imaging techniques facilitating needle placement, greater safety of fine needle and advances in cytology.CT because of its characteristic high spatial and density resolution, permits the accurate localization of anylesion in the body. Because of the ability of CT scans to precisely localize lesions and biopsy needle, along withthe delineation of adjacent structure, it is widely used in percutaneous biopsy. Sixty-six cases of CT-guidedpercutaneous fine-needle biopsy were performed in order to diagnose suspected malignant or infectious disease(49malignant and 17 infectious) over a 7-month period(June 1984 through Dec. 1984). Most of these procedures wereperformed on, but not limited to, the lung(21), liver(20), and pancreas(7). The spine and nasopharynx could alsosafely be biopsied. 4 cases of hepatic abscesses were successfully drained following insertion of drainingcatheter under the CT-guidance. The overall accuracy of both suspected malignant and infectious disease was 82%.Complication rate was low as 6%(4 cases only in thorax). Neither complication require any further intervention.Three were self-limited pneumothoraces and one was minimal hemorrhage around the needle tract.

The Ewing's sarcoma comprises approximately less than 10 percent of malignant bone tumors and 5 percent of allbone tumors, occures in almost all bones of the body, and presents a widely divergent roentgenographicmanifestations. The tarsal bones are involved only 2 percent in the Ewing's sarcoma. Two cases experienced byauthors and ten cases published in literatures of Ewing's sarcoma of the tarsal bone were analizedretrospectively. The result were as follows; 1. Of tarsal bones, the calcaneus was 7 cases, the talus 4 cases,cuneiform 1 case. 2. Female was affected more commonly than male, the ratio being 4 to 1 in the tarsal bones. 3.About sixty percent of total case in the tarsal bones had evidence of diffuse sclerotic pattern. All the cases ofthe talus had evidence of diffuse sclerotic pattern. 4. The diseases to be considered in differential diagnosisare as follows: avascular necrosis, tuberculous osteomyelitis, osteosarcoma, and pyogenic osteomyelitis. 5. Thediffuse sclerosis radiographically showed a close relation with dead bone resulting from avascular necrosis due totumor infiltration histologically. Periosteal reactive new bone and osteoid deposition on the dead bone were alsocorrelated with diffuse sclerosis. 6. Because it is difficult to differentiate sclerotic lesions in the tarsalbones by radiographic methods alone, all such lesions should be subject to biopsy as early as possible.

Diagnosis of knee jont pathology has been mainly dependent on clinical manifestations and invasive proceduressuch as arthrography and arthroscopy etc. However, these procedures are invasive. Arthroscopy is perfromed undergeneral anesthesia. Recently, with development of high resuloution CT with thin slices and multiplanarreconstructions capability, CT could be used to verify the internal structures of knee joint in noninvasive orless invasive way. From June ot December 1985, authors have experienced 19 cases of the knee joint CT. Among them,13 cases were operated and confirmed. We concluded as follows. 1. The diagnostic accuracy of the knee CT was 100%in lateral meniscal tearing, 92.3% in medial meniscal tearing, 92.3% in detachment of lateral collateral ligament,92.3% in medial collateral ligament, 100% in tearing of cruciate ligaments. 2. CT could be considered as a primarydiagnostic procedure in the knee pathology rather than more invasive arthrocopy or arthrography. 3. For theaccurate diagnosis of knee joint pathology, CT which can obtain thin slies, high resolution, multiplanarreconstructions is indispensable.

Tufted angioma is a rare, acquired vascular tumor, most commonly presenting in the first year of life, which was first described by Wilson Jones in 1979. Spontaneous resolution of this tumor are known to be very rare and local recurrence often occurs unless the tumor is excised completely. We present two cases of tufted angioma developed in two 1-year-old girls. Skin biopsy in a case showed compatible findings with tufted angioma and the other was diagnosed at an other hospital. The lesions were treated with intralesional injections of triamcinolone acetonide and showed marked improvement. During follow up period, the lesions kept improving.

Anterior cervical fusion has enjoyed an increasing acceptance and frequency of utilization in the treatment of symptomatic degenerative, traumatic, and neoplastic disorders. Since the introduction of plate systems, cervical fusion with fixation has become popularized. We present our experiences of 152 cases of cervical fusion in degenerative and traumatic lesions, focusing on their surgical results and complications, along with our opinions about the various plate systems we used. Between March 1993 and May 1996, 152 patients with symptomatic degenerative and traumatic cervical lesions between C3-4 and C7-T1 levels were treated with anterior cervical fusions. These patients were retrospectively studied according to their medical records and radiological studies. A comparison between various plate systems were also done. There were 110 men and 42 women, aged from 21 to 77 years. Mean follow up period was 17 months. Mean fused segments were 1.4. Various plate systems were used: Caspar plate system in 14 patients; Top plate in 102; Orion plate in 21; and none in 15. Dislodgement of bone graft, screw loosening, and fusion failure that required reoperation were occurred in 8 cases. None of them were initially treated with unicortical type screws. Asymptomatic esophageal perforation was developed in one case among them. In conclusion, anterior cervical fusion with screw plate system can be carried out with acceptable complication rate. Although relative follow up period was short, we concluded that the locking type screw plate system was superior than the classic bicortical screw system in their procedural simplicity, unnecessary penetration of posterior cortex, and elimination of the fear for the neurological complication.

Churg-Strauss syndrome is a clinicopathologic disorder of severe asthma, fever , and eosinophilia together with systemic vasculitis involving various organ systems. Characteristic cutaneous lesions include erythematous maculopapules resembling erythema multiforme, hemorrhagic lesions, and cutaneous and subcutaneous nodules. Histologically, extravascular granuloma and leukocytoclastic vasculitis are the most common findings. We report a case of 40-year-old woman who presented with generalized multiple hemorrhagic bullae that had developed 1 month ago. Previously, She had allergic rhinitis and asthma. Laboratory studies revealed peripheral blood eosinophilia, and positive p-ANCA. Skin biopsy revealed eosinophilic infiltrates and leukocytoclastic vasculitis.

We present a rare case of a pituitary adenoma revealing a sedimentation level on MRI, which has not been previously documented. This 55-year-old woman was referred with the diagnosis of craniopharyngioma. She presented with four-month history of progressive headache and visual dimness. Neurological examination revealed a bitemporal hemianopsia and decreased visual acuity. Laboratory data including endocrine examination were unremarkable. An additional three-dimensional MRI was taken for further evaluation, and demonstrated a sedimentation level within the tumor. The patient underwent transcranial removal of the tumor. About 12cc of dark-red blood was aspirated from the tumor. Histological examination revealed a pituitary adenoma with hemorrhage. Postoperatively, the patient showed gradual improvement of visual function. Considering that the pituitary adenoma is one of more common tumors that cause tumoral bleeding, a cystic sellar tumor that has a sedimentation level should be sought first for a pituitary adenoma rather than a craniopharyngioma. This may have an important impact when deciding surgical approach.

In order to define the prognostic implications of cervical myelopathy, we conducted a morphometrical analysis of spinal cords in patients suffering from this condition. Twenty patients who had undergone laminoplasty for their cervical myelopathy were the subject of this study. Cervical spondylosis was diagnosed in 14 patients and ossification of the posterior longitudinal ligament in six. Signal change of the spinal cord, its anteroposterior diameter, and the number of stenotic segments were determined by pre- and postoperative magnetic resonance imaging and simple X-ray. The patients' neurological status before and after surgery was evaluated by the Neurosurgical Cervical Scale. Patients whose cord revealed no signal change had better recovery rates than those who showed change (77.5% vs. 60.5%). The wider the diameter of the cord, the better the outcome of surgery(p<0.05 on one-way ANOVA). The number of stenotic segments was not significantly related to recovery rate. In conclusion, focal morphological changes of the spinal cord, regardless of the general stenotic area, are the main factors determining the outcomes of surgery.
