During last 10 years we experienced 25 cases of C.N.S. cysticercosis. Now clinical analysis and evaluation of our cases were made and the results are followings; 1. Prevalence in man and women are nearly same and about 70% of cases are distributed between 20-50 years old. 2. According to Nieto's classification, mostly are ventricular (44%) and parenchymal type (36%). 3. Clinical manifestations were IICP (92%), focal neurological deficits (68%), seizure (48%), altered mental status (36%) and others listed on table 7. 4. In ventricular type, IICP and cerebellar dysfunction signs were predominated but seizure and focal neurological deficits were commonly seen in parenchymal type. 5. Subcutaneous cysticercus nodules were palpated in 32% of cases. 6. Positive stool ova was observed in 29% of cases. 7. Radiologic studies revealed as followings: 16% of cases showed abnormal findings on plain film, 84% on angiography, 94% on ventriculography and 100% on computed tomography and myelography. Computed tomography looks like most helpful diagnostic method for C.N.S. cysticercosis, they usually revealed lucent cystic lesion, hydrocephalic findings and contrast enhancement. 8. Suboccipital craniectomy, craniotomy with removal of parenchymal cyst or laminectomy were done according to location and types of lesion. 72% of operated cases revealed good results and mortality was 4% of cases.

The management of pineal region tumor remains controversial. This paper reports a case of pineocytoma which was attempted to improve treatment planning by the use of clinical features, computerized tomography, and markers for germ-cell tumor. A presumptive diagnosis could be made and this tumor less likely to respond to radiotherapy was subjected to primary surgery.

A 44-year-old female with cervical cord compression signs had myelographic and computerized tomographic evidence of extradural spinal cord compression without any tuberculous bony lesion or cold abscess. At surgery, cervical spinal cord was compressed by extraosseous extradural granulomatous tissue which was histologically proved a very rare localized extradural tuberculous granuloma.

The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.

Objectives: In this study, we aimed to investigate the cardiopulmonary resuscitation (CPR)-related knowledge, attitude, and performance among dental hygienists working in the hospitals. We believe that it is important to develop CPR education programs that would enable dental hygienists to offer accurate and timely aid in emergency situations. Methods: From June 20 to August 20, 2019, 220 dental hygienists at seven selected dental hospitals located in Gwangju Metropolitan City and Jeollanam-do, South Korea were requested to fill a questionnaire as part of a survey. The data regarding the general characteristics, CPR-related characteristics, and CPR-related knowledge, approach, and performance were collected, and analyzed using independent t-tests, oneway analysis of variance (ANOVA), Pearson’s correlation coefficient, and simple regression analysis using the SPSS Windows ver. 25.0. Results: Correlation analysis revealed that high CPR-related knowledge and a more positive approach towards CPR are both associated with high confidence in performing CPR (r=0.37, r=0.415, r=0.605). Furthermore, factors, such as high CPR-related knowledge, positive attitude towards CPR, knowledge regarding the location of automated external defibrillators (AEDs) in the hospital, and AED training experience significantly affects the CPR-related performance. Conclusions Therefore, it is important to develop systematic and beneficial educational programs and provide and update educational material regularly in dental hospitals with an aim to improve CPR-related knowledge and attitude among the dental hygienists.

Magnetic resonance (MR) images of 14 consecutive patients with pathologically proven primary intracranial lymphoma were reviewed. All patients had a brain MR imaging before any treatment and were immunologically competent. MR images were acquired using 2.07 (n= 6) or 0.57 (n= 8) machine. The MR images were reviewed regarding the location, multiplicity, size, signal intensity, margin, shape, and the extent of surrounding edema of the lesion. Seven patients had multiple lesions, 2 to 4 in number. A total of 26 lesions was found; 25 were parenchymal lesions and one was dural lesion. The location of tumor was either central (r= 11) or peripheral (n= 14). The size of tumor was variable ranging from 0.6cm to 6.0cm in its maximal diameter. The tumors were isointense (n= 19) or hypointense (n= 7) relative to gray matter on T1-weighted images, isointense (n= 24) or hyperintense (n=2) on proton-density weighted images, and isointense (n= 21) or hyperintense (n= 5) on 78-weighted images. On gadolinium-enhanced T1-weighted images of 13 patients strong enhancement was seen in 22 of 23 lesions. Nineteen lesions showed smooth, well-defined margin, whereas remaining 7 lesions showed irregular, ill-defined margin. The shape of the tumor was diverse; round of ovoid (n= 15), lobulated (n= 9), or short linear (n= 2). These results suggest that one should consider the diagnosis of CNS lymphoma in cases with single or multiple masses that abut CSF space and show iso-or similar intensity to gray matter with strong enhancement on MR images.

PURPOSE: To elucidate the incidence of Gd-DTPA enhancement of the optic nerve/sheath complex (ONC) in patients with various ophthalmopathies using fat-suppression MRI. MATERIALS AND METHODS: Orbit MRI with fat-suppression technique (ChemSat) was performed in 58 patients with normal and various orbital lesions. The fat-suppression MR was done with and without Gd-DTPA injection in all cases. MR findings were reviewed retrospectively in a blind fashion with respect to presence or absence of contrast enhancement of the O NC. RESULTS: Contrast enhancement of the ONC was seen in 86% (6/7) of cavernous sinus lesions, 80% (8/10) of intraconal lesions excluding the ONC, 57% (16/28) of ONC lesions, 38% (3/8) of ocular lesions, and 2% (1/55) of normal orbits. The ONC enhancement was the most common in optic nerve/sheath tumors (10/10), and pseudotumors (6/6), cavernous sinus dural arteriovenous malformations (3/3) and cavernous sinus thrombosis (2/2), and less frequently seen in optic neuritis (3/14). CONCLUSION: Enhancement of the ONC may be seen in lesions of the cavernous sinusand orbit other than optic nerve/sheath lesion.
