Intracranial lipomas are rare tumor which are usually found along the midline cerebral cisterns. A case of sylvian lipoma located usually at sylvian fissure was diagnosed by CT scanning and was confirmed with operation. Only partial resection could be done. The literature was reviewed and therapeutic options are proposed.

A clinical analysis and follow-up study were performed with 35 cases of subarachnoid hemorrhage of unknown etiology among 217 cases of spontaneous subarachnoid hemorrhage who were diagnosed by cerebral pan-angiohraphy and brain C-T scan and treated at department of neurosurgery, Chonju Presbyterian Medical Center from 1977 to 1982. The duration of follow-up study was 6 months to 8 years(mean 4.4years). The author obtained the following results. 1) Subarachnoid hemorrhage of unknown etiology was 16% of 217 cases of spontaneous hemorrhage. 2) The incidence of subarachnoid hemorrhage of unknown etiology was high in 5th decade and higher in women. 3) Manifestations of subarachnoid hemorrhage of unknown etiology were similar to those of ruptured aneurysm. 4) When primary cerebral pan-angiography was normal, the secondary cerebral pan-angiography was not so meaningful. 5) The overall prognosis of the cases of unknown etiology was good in 30 among 35 cases(86%) who were able to return to their previous occupation. 6) Age and blood pressure were probably major prognostic factor.

PURPOSE: To evaluate the clinical and radiological results of patients that underwent total knee replacement arthroplasty (TKRA) using a NexGen(R). implant, and who were followed up for at least 2 years. MATERIALS AND METHODS: Between July 1996 and June 2002, 100 knees in 67 patients, and followed up for at least 2 years following TKRA using a NexGen(R). implant were retrospectively assessed for clinical and radiological results using the assessment standards of the Knee and Functional Score of the American Knee Society. RESULTS: The average preoperative range of motion in patients with osteoarthritis and rheumatoid arthritis were 107.4degrees (50-140degrees) and 105.8degrees (70-120degrees), respectively, which had improved to 127.2degrees (85-140degrees) and 125.6degrees (90-140degrees), respectively, at the final follow up. In addition, the preoperative flexion contracture improved from 11.3degrees (0-30degrees) and 10.6degrees (0-30degrees) to 1.3degrees (0-15degrees) and 3degrees (0-15degrees) postoperatively. The results using the assessment standards of the Knee and Functional Score of the American Knee Society were improved from 62 (35-82) and 40 (0-70) to 95.8 (87-100) and 97 (70-100) in patients with osteoarthritis, whereas the patients with rheumatoid arthritis were improved from 53.8 (32-73) and 36 (0-50) to 95.1 (89-98) and 79 (55-95). As a complication, infection occurred in 2 cases; they were given a reimplantation. CONCLUSION: TKRA using a NexGen(R). implant showed satisfactory improvement in pain relief and function, such as range of motion, as well as a lower occurrence rate of complications.

Median raphe canal is a uncommon disease and represents a defect in the embryologic development of male genitalia. It occurs most commonly near the glans penis, but may occur anywhere from the urethral meatus to the anus, and is lined by endodermal or ectodermal epithelium. Surgical excision is the treatment of choice. we report a median raphe canal on the ventral aspect of the penis and the scrotum with review of literatures.

Several cases of pulmonary air embolisms during surgery have been reported. However, such incidences are very rare during endoscopic surgeries. A 5-year-old boy with third ventricular arachnoid cyst and hydrocephalus underwent endoscopic third ventriculostomy under the general anesthesia, during which continuous intraventricular irrigation was maintained with normal saline. During the procedure, arterial and transcutaneous oxygen tension and end-tidal carbon dioxide tension became suddenly decreased while arterial carbon dioxide tension increased. Within 3 minutes after the inspired gas mixture was changed to 100% oxygen, the patient's respiratory variables returned to near base line. The second attack occured about 10 minutes later and decreased arterial oxygen tension with increased arterial carbon dioxide tension continued for about 5 minutes. After waking up from anesthesia, the patient suffered a generalized seizure attacks that was managed with anticonvusant therapy. We believe that we are the first to report an attack of pulmonary air emblism during brain endoscopic procedure. It was reported with the review of literatures.

Lipid cell tumors of the ovary are the rarest functional ovarian neoplasm, and malignant variants are unusual. Although rare, due to endocrinological activity, these tumors are of great clinical interest. Recently we experienced a case of lipid cell tumor of the right ovary in 21 years old female, who presented with menometrorrhagia and menorrhagia, and reported it with a brief review of literatures.

OBJECTIVE: To evaluate the performance and reproducibility of a computer-aided detection (CAD) system in mediolateral oblique (MLO) digital mammograms taken serially, without release of breast compression. MATERIALS AND METHODS: A CAD system was applied preoperatively to the full-field digital mammograms of two MLO views taken without release of breast compression in 82 patients (age range: 33-83 years; mean age: 49 years) with previously diagnosed breast cancers. The total number of visible lesion components in 82 patients was 101: 66 masses and 35 microcalcifications. We analyzed the sensitivity and reproducibility of the CAD marks. RESULTS: he sensitivity of the CAD system for first MLO views was 71% (47/66) for masses and 80% (28/35) for microcalcifications. The sensitivity of the CAD system for second MLO views was 68% (45/66) for masses and 17% (6/35) for microcalcifications. In 84 ipsilateral serial MLO image sets (two patients had bilateral cancers), identical images, regardless of the existence of CAD marks, were obtained for 35% (29/84) and identical images with CAD marks were obtained for 29% (23/78). Identical images, regardless of the existence of CAD marks, for contralateral MLO images were 65% (52/80) and identical images with CAD marks were obtained for 28% (11/39). The reproducibility of CAD marks for the true positive masses in serial MLO views was 84% (42/50) and that for the true positive microcalcifications was 0% (0/34). CONCLUSION: The CAD system in digital mammograms showed a high sensitivity for detecting masses and microcalcifications. However, reproducibility of microcalcification marks was very low in MLO views taken serially without release of breast compression. Minute positional change and patient movement can alter the images and result in a significant effect on the algorithm utilized by the CAD for detecting microcalcifications.

We treated 8 patients with large pituitary adenomas(4 females, 4 males) with bromocriptine. In all patients the level of prolactin was decreased to within the normal range and in most patients the size of tumor was decreased remarkably, high cure rate of large pituitary tumor fallowing operation after pretreated bromocriptine was obtained.
