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.

Angioma serpiginosum is a rare vascular naevoid disorder due to progressive ectatic dilatation of capillaries in the papillary dermis. We report two cases of angioma serpiginosum. A 24-year-old woman presented with asymptomatic multiple deeply red macules arranged in a serpiginous pattern on the left posterior thigh. In the other case, an 8-year-old girl had asymptomatic red nonpalpable puncta that were grouped closely together in a linear pattern from the left lower abdomen to thigh. On the histopathological examination, both cases commonly showed grouped, dilated, ectatic vessels in the upper dermis. These clinical and histopathological findings were typical of angioma serpiginosum.

Eosinophilic gastroenteritis is characterized by peripheral eosinophilia, eosinophilic infiltration of the bowel and gastrointestinal symptoms. The disease may affect any area of the gastrointestinal tract. Various manifestations are present, corresponding to the predominant layer of the eosinophilic infiltration. We experienced a case of eosinophilic gastroenteritis presenting as protein-losing enteropathy in a 36-year old male patient with acute upper abdominal pain and watery diarrhea. He showed peripheral eosinophilia, hypoalbuminemia, penile., thigh and ankle edema. The patient was treated with oral corticosteroid, and supportive care such as parenteral albumin, fluid and electrolytes. Almost all symptoms resloved within 1 week. The present report concerns a case of eosinophilic gastroenteritis associated with protein loss. Cases, of eosinophilic gastroenteritis with protein-losing enteropathy are not common. To our knowledge, no case has reported in Korea. So we report this case with brief review of the literature.

A 54-year-old woman with severe bullous pemphigoid (BP) associated with insulin dependent diabetes mellitus (DM), who showed unresponsiveness to conventional therapy with corticosteroids in combination of either cyclosporme or dapsone, was successfully treated with plasmapheresis followed each time by 3 successive days of pulse therapy of cyclophosphamide (500mg, intravenously). After six times of plasmapheresis, anti-basement membrane zone (BMZ) antibody titer decreased from 1:1280 to 1:40 and no new lesions developed at all. In severe refractory BP patients with uncontrolled DM, plasmapheresis is one of the valuable treatment modalities for a short period and the need for corticosteroids thus avoiding corticosteroid induced side effects. Herein we report a case of BP with uncontrolled DM who showed an excellent response to a low dose of corticosteroid and 150 mg oral azathioprine following plasmapheresis and cyclophosphamide pulse therapy.

The purpose of this study is to describe the magnetic resonance imaging (MR) findings of metastatic brain tumors with emphasis on the signal intensities of the lesion on MR. Thirty four patients with intracranial metastases were studies with MR imaging. The diagnosis was established on the basis of either brain biopsy or combination of brain MR findings and the presence of primary tumors. The primary tumors include lung cancer (n=18), breast cancer (n=3), stomach cancer (n=3), rectal cancer (n=1), renal cell carcinoma (n=1), hepatocellular carcinoma(n=1), ovarian cancer (n=1), thyroid cancer (n=1), melanoma (n=1) and unknown primary sites (n=4). The parenchymal lesions were solitary in 35% (12/34) and multiple in 65% (22/34). The size of the lesions was variable, ranging from several millimeters to 5cm in diameter. The corticomedullar junction of the cerebral heispheres was the most common location of the lesions (68%). The signal intensity of solid portion of the lesions was usually either isointense (44%) or hypointense (29%) on T1-weighted images, whereas it appeared in isointense (47%), hypointense (8%) or hyperintense (11%) on proton density-weighted or T2-weighted images. The remaining cases showed mixed signal intensities. The enhancement patterns were variable including nodular (<1cm) (6%), homogenous (19%), heterogeneous (10%), ring-like enhancement (22%) or mixed pattern(43%). The size of surrounding edema was larger than the tumor diameter in 76%. In conclusion, although there are no specific MR findings of intracranial metastasis except multiplicity, intracranial metastasis should be included in differential diagnosis with high priority, when a solitary mass showing isointensity on boty T1-and T2-weighted images with massive surrounding edema, especially in the corticomedullary junction of the cerebral hemispheres is encountered.
