Hair takes a great role in featuring man's appearance and absence of hair can causes troubles in physical and psychological aspects. Many efforts have been made to treat male pattern baldness, including medical therapy and surgical correction, but there is not a definite and eternal method of treatment. Even though the diagnosis of male pattern baldness can be made with its characteristic clinical manifestations, histopathological study must be done for definite diagnosis. Author obtained biopsy material from the frontal progressive baldness area and the occipital non-baldness area with punch biopsy in 20 patients who were diagnosed to be Type II and III male pattern baldness according to the Norwood classification. A comparative study was done in the basis of histopathology using serial vertical section of the biopsy materia with the aid of light microscope and the results are as follows : 1. The average number of total hair in the frontal area was on third than that of occipital area and the number of anagen hair was less in the frontal area. The number of telogen hair in the frontal area was seven times more than that of occipital area. 2. The thickness of epidermis and dermis in the frontal area was thinner than that of occipital area. 3. The infiltration of inflammatory cells in the periadnexal field like blood vessels, hair follicles, sebaceous glands, eccrine glands was more prominent in the frontal area than in the occipatal area. 4. Perifollicular fibrosis and hypertrophy of arrector pilli muscle were more remarkable in the frontal area compared with that of occipital area. 5. There was no difference between the frontal and occipiral area in the number of lobules of sebaceous glands.

PURPOSE: To evaluate the clinical efficacy of balloon catheter dilatation in the treatment of esophageal achalasia. MATERIALS AND METHODS: Seven patients(three males and four females) with esopha-geal achalasia were treated with balloon catheter dilatation. Balloon catheters of variable sizes were used depending on patient's conditions. The patients were followed up over a period of 12-39months. RESULTS: Balloon catheter dilatation in esophageal achalasia was successful in all patients without esophageal perforation. All patients were relieved from dysphagia. Recurrence was not found in 5 patients on long term follow-up study, but was seen in 2 patients after 18 and 21 months, respectively. CONCLUSION: Balloon catheter dilatation was a safe and effective method in the treatment of esophageal achalasia with low recurrence rate of 29% on follow-up study.

PURPOSE: To describe the magnetic resonance (MR) findings of intracranial dural arteriovenous fistulae (DAVF) and associated venous hypertensive diseases, and to determine their diagnostic value. MATERIALS AND METHODS: MR Imagings of twelve cases of angiographically-proven intracranial DAVF were analyzed. The presence of signal voids, dilatation of involved dural sinus, the dilatation of the extra/intradural venous system, high signal intensity on T2 weighted image, cerebral edema, intracranial hemorrhage, and hydrocephalus were retrospectively analyzed. MR findings and angiographic classification were compared. RESULTS: In 11 of 12 patients (92%), MR revealed the location of DAVF. In five cases, these were cavernous, and in six, they were extracavernous; the locations of the latter were as follows: superior sagittal sinus (SSS), 4: torcula, 1; lateral sinus & SSS, 1. Except for the lateral sinus lesion, all the DAVF seen in thses 11 patients showed the presence of signal voids and dilatation of the involved dural sinus. Findings of associated venous hypertensive disease, namely dilatation of the superior ophthalmic vein and cortical venous system, cerebral edema, and high signal intensity on T2-weighted images were observed in three cavernous lesions (50%), but all extracavernous DAVF (100%) showed associated venous hypertensive disease. When the grade of angiographic classification was high and reflux of sinus blood to the cortical vein was seen on angiography, the MR findings of intracranial venous hypertension showed good correlation. CONCLUSION: The MR findings of DAVF include dilatation of the dural sinus and signal voids of feeding arteries and draining vein. Other findings which suggest intracranial venohypertensive disease are dilatation of the cortical and medullary vein, hydrocephallus, cerebral edema and intracranial hamorrhage. These and the angiographic findings correlate well and suggest that in the diagnosis of DAVF and the detection of intracanial venohypertension, MR is a non-invasivse technique which can be use be usefully employed before final diagnosis by angiography.

PURPOSE: To determine the clinical and mammographic characteristics of primary lymphoma of the breast. MATERIALS AND METHODS: The clinical and mammographic records of five patients (six breasts; bilateral involvement in one patient) with histologically-proven lymphoma of the breast were retrospectively reviewed. RESULTS: All patients had complained of a palpable tender mass with relatively rapid growth over a period of about 3 months. In five cases, the mass was located in the right breast and in one case in the left. Mammography revealed diffuse increased opacity of the entire breast in three cases, a homogeneous well-defined mass in one, multiple well-defined masses in one, and ill-defined lobulated opacity in one. Skin thickening and architectural distortion was seen in one case, and axillary lymphadenopathy in two. In no case was microcalcification and nipple retraction seen. CONCLUSION: In primary breast lymphoma, mammographic finding are non-specific. When a breast grows rapidly and is tender, however, and mammography shows a relatively large well defined mass and associated axillary lymphadenoapathy, the possibility of primary lymphoma should be considered.

PURPOSE: To evaluate characteristic CT features of twisted ovarian tumors and to assess the diagnostic value of the existence of twisted vascular pedicle in torsion of ovarian tumors. MATERIALS AND METHODS: Weretrospectively reviewed the clinical and CT findings in eleven patients with ovarian tumor torsion confirmed bysurgery. Pre- and post-contrast CT were available in nine patients and post-contrast CT in two. All twisted ovaries, tubes, and tumors showed hemorrhagic infarction and necrosis. RESULTS: All patients had twisted vascular pedicle of the ovarian tumor evaluated by CT. Eight patients with left ovarian tumor had twisted vascular pedicleon the left side of the tumor, and three patients with right ovarian tumor on the right side of the tumor. Themorphologic characteristics of twisted vascular pedicle were coiled target appearance (4 cases), beak appearance(3 cases), doughnut appearance (3 cases), and mass with irregular margin (1 case). High density on precontrast CT scan was present in the pedicle in four cases and linear contrast enhancement was seen in the peripheral portionof the pedicle in four cases. The shape, density and location of ovarian tumors were inconsistent, however, contrast enhancement was not seen in all patients. Other findings were uterine deviation, loss of fat plane andpelvic fluid. CONCLUSION: Detection of twisted vascular pedicle by CT may be useful for the diagnosis of ovariantumor torsion.

Aspergillus endocarditis is an uncommon, but often fatal, disease that usually occurs in patients who have had prior cardiac surgery. Endophthalmitis is a very rare complication of infective endocarditis, especially at presentation. We report a case of Aspergillus endocarditis in a 68-year-old woman who presented with endophthalmitis.

Epidural hemangioma is a rare neoplasm which consists of 4% of epidural tumors and 12% of hemangiomas of vertebral column. But most of them are secondary involvement of epidural space by vertebral hemangioma and pure epidural hemangioma is very rare. Reported cases involve thoracic & lumbar level. Neural foramen & paraspinal region are usually invaded by the tumor mass. Clinical symptoms are similar to simple low back pain or disc herniation. Myelography, CT & MRI are helpful to make diagnosis but pathologic finding is important for final diagnosis. Authors are reporting a case of epidural hemangioma which was difficult to differentiate from HIVD by symptomatology & radiologic findings alone.
