PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

BACKGROUND: It has been known that arterial carbon dioxide tension is 4~5 mmHg higher than end-tidal carbon dioxide tension in healthy adults during general anesthesia. But negative arterial to end-tidal PCO2 difference was reported in pregnant patients undergoing cesarean section. The purpose of this study was to elucidate the difference between arterial and end-tidal PCO2 in anesthetized patients with reduced functional residual capacity. METHODS: 90 patients were divided into 3 groups i.e. control group (n=30), obese group (n=20, body weight more than 20% greater than ideal weight), pregnant group (n=40). All patients had no cardiac or respiratory abnormalities and never smoked. Arterial blood gas analysis and measurement of end-tidal PCO2 were done 20 minutes after induction of anesthesia in control and obese group and just before uterine incision and 20 minutes after fetal delivery in pregnant group. RESULTS: There were significant correlations between arterial and end-tidal PCO2 in all groups. The incidences of negative arterial to end-tidal PCO2 difference were 10% in control group, 40% in obese group, 42.5% in pregnant group (p<0.05). CONCLUSION: From this study, it is concluded that patients with reduced functional residual capacity have more incidences of negativity than normal patients in the values of arterial to end-tidal PCO2 difference during general anesthesia. So when the tight control of PaCO2 is required in patients with reduced FRC, we recommend to measure PaCO2 for better anesthetic management.

In clinical surgery, there are frequent needs for communication between the house staff and the attending physician in an emergency situation. It's often insufficient for the house staff to make a decision through the information which is delivered in the form of only voice through the telephone line. To overcome the limitation of voice communication, we have designed an emergency teleradiology system which can be used for emergency surgical and medical decision making. The system can transmit the high quality images of CT, MRI, and other X-ray data using a PC attached to a modem through the conventional telephone line. Progressive transmission adopted in the system enables us to efficiently utilize the band-width of telephone line which is typically very low. The iterative residual coding/decoding algorithm compresses various medical images effectively, and thus fast-transmission of images date helps the house staff to perceive the status of emergent patient and make a fast and correct decision about the patient. The system also satisfies design requirements such as low-cost, ease of operation and interactive image communication including voice. 'Teleradiology system' proposed in this paper has been installed and operated in the emergency care unit of Severance Hospital, and as a result, it is effective in the emergency situations.

Primitive neuroectodermal tumors(PNETs) may be a term established recently for a tumor group(?) which is composed of prominent undifferentiated cells with variable foci of differentiation along glial and neuronal lines. The authors experienced a case of 'primitive glioma' regarded as a subclass of PNETs, in a 14 year old boy who had suffered from headache and vomiting for about 40 days prior to admission. Brain CT and angiographic studies reveal a huge hypovascular mass lesion with multiple cysts in the left frontal lobe. The patient was satisfactorily treated by total tumor excision and following irradiation, and is now in follow up. We present the case with review of the literatures.

Intracranial calcification is relatively common, but calcification of chronic subdural hematoma is rare condition. Nevertheless, already in 1884 Von Rokitansky had described a calcified chronic subdural hematoma found at autopsy. Subsequently Lewis(1889), Elsner(1896), and O'sullivan(1925) mentioned calcification of intracranial hematoma. In 1930, Goldham reported the first case treated by operation. A 15-year-old Korean male was admitted to this hospital because of a episode of generalized epileptic seizure, one day before admission. Past history was unknown about head injury and his past birth condition. Patient has complained weakness of right upper and lower extremely since his infant. Neurological examination revealed the left hemiparesis, but others were normal. Skull X-ray films showed dense conglomerated calcific density with surrounding rim like lucency in left fronto-parietal region. Left carotid angiogram revealed no abnormalities except hypoplasia of left hemisphere. Brain computed tomogram demonstrated hyperdense subdural mass surrounding decreased parenchymal density in left fronto-parietal region. A craniectomy was performed for removal of the calcified mass. A oval concaved bony hard mass was found in subdural space. The calcified bony hard mass was adherent with the surface of cortex by loose sonnective tissue. We removed the bony hard mass completely. The postoperative course was very satisfactory and seizure has not been appeared after discharge. Microscopic findings demonstrated ossification and fibrosis, consisting with old hematoma which showed up a calcification of chronic subdural hematoma.
