PURPOSE: To measure the size of normal corpus callosum in each portion using objective and reproducible method with MRI and evaluation of morphological change of corpus callosum by grade of hydrocephalus. MATERIALS AND METHODS: Midsagittal Tl-weighted MR imaging of the corpus callosum was investigated in 41 volunteers of normal Korean adults and 19 patients with hydrocephalus. Corpus callosum was measured for the anteroposterior length(A), height(B), and the thickness of genu(C), body (D), splenium(E), and the narrowest portion of body(F). And the analysis of morphology and signal intensity of the corpus callosum were also evaluated. Hydrocephalus was graded as mild, moderate, and severe, and comparision of thickness with normal corpus callosum in each portion was done. RESULTS: The mean length and height were 72.3mm, 28.6mm in male, and 70.7ram, 28.9mm in female. And the mean dimention for C, D, E, and F were 13.1 ram, 8ram, 13.2mm, 5.2ram in male, and 12.8mm, 7.5ram, 12.3 ram, 5mm in female. The morphology of normal corpus callosum was "hook" shaped on midline sagittal Tl-weighted image. Narrowing at posterior third portion of body were present on 30 cases(73.2%) and even in thickness of the body in 11 cases(26.8%). The signal intensity of the corpus callosum on midsagittal Tl-weighted spin echo image of normal cases was homogeneous hyperintense as compared with cerebral gray matter. In hydrocephalus, A and B were increased and other portions were decreased in thickhess. Genu and the narrowest portion of body showed significant difference of thickness according to the grade of hydrocephalus. CONCLUSION: The mean dimention of all portion of corpus callosum were larger in male than female except for callosal height but not significant statistically with the exception of splenium. Hydrocephalus lead to morphological change of the corpus callosum. Among the portion of corpus callosum, genu and the narrowest portion of the body were thought to be the most sensitive indicators of degree in hydrocephalus.

PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

Parry-Romberg syndrome, first described in 1825 by Parry and in 1846 by Romberg, is a rare disorder characterized by a progressive hemifacial atrophy of the skin and adipose tissue and atrophy of muscle, cartilage, and underlying bony structures. It is sometimes accompanied with such complications as ophthalmologic abnormality, localized alopecia and neurologic symptoms, for example, contralateral Jacksonian epilepsy, trigeminal neuralgia, migrane and hemiplegia. The onset is slow and progressive, starting at the first or second decade of life and lasting for 2-10 years, ending with a face being "burned out". It is often associated with epilepsy but the link between these two conditions is poorly understood. In patients with progressive hemifacial atrophy, a high incidence of abnormal neuroradiologic findings in the brain has been reported. Brain MRI findings include cerebral hemiatrophy, cortical calcification, unilateral focal infarction in the corpus callosum, diffuse deep and subcortical white matter signal changes and mild cortical thickening. We report a case of Parry-Romberg syndrome in a 5-year-old boy who had a progressive Rt. facial hemiatrophy with intractable epilepsy and basal ganglia calcification from brain MRI.

We have experienced a case of pericardial tuberculoma, a very rare disease, with massive pericardial effusion in a 63-year-old veteran. He wdimensional echocardiography. Computed tomographic scans confirmed the presence of a pericardial mass and clinically unsuspected "lung mass". The presence of the lung mass led us a diagnostic and therapeutic dilemma. Surgery confirmed the pericardial mass which revealed tuberculosis by patholohy and loculated pleural effusion at the major fissure, so-called "phantom tumor", not a lung mass.

We used duplex and color Doppler sonography to assess the hemodynamic function of the penis in normal male and in patients with impotence to determine the competence of penile vascular system. The measured parameters are the diameter. peak-systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI) in each cavernosal artery before and after injection of 10ug of PGE, at 5, 10, 15 and 20 minutes. The results obtained are as follows: 1. In 20 normal control group after PGE, injection, the values of maximal and minimal mean PSV were 47.0+/-19.5 cm/sec and 35.7+/-20.9 cm/sec, the values of maximal and minimal mean EDV, 2.7+/-3.7 cm/sec and 0.6+/-1.6 cm/sec and the values of maximal and minimal mean RI, 1. 0+/-0.0 and 0.9+/-0.1, each respectively. 2. In 5 arteriogenic impotence patients after PGE. injection, the values of maximal and minima1 mean PSV were 16.2+/-7,8 cm/sec and 10.5+/-5.1 cm/sec. the values of maximal and minimal mean EDV, 2.4+/-1.7 cm/sec and 1.5+/-1.5 cm/sec and the values of maximal and minimal mean RI, 0.8+/-0.1 and 0.8+/-0.2, each respectively. 3. In 6 venogenic impotence patients after PGE. injection, the values of maximal and minimal mean PSV were 39.0+/-33.6 cm/sec and 33.8+/-26.1 cm/sec, the values of maximal and minimal mean EDV, 7.5+/-4.4 cm/sec and 4.7+/-2.9 cm/sec and the values of maximal and minimal mean RI, 0.8+/-0.1 and 0.8+/-0.1, each respectively. These findings suggest that PSV and EDV are important parameters for the diagnosis of arteriogenic and venogenic impotence, respectively. It is thought that duplex and color Doppler sonography with intracavernous PGE, injection is valuable screening test for vasculogenic impotence.
