Hereditary anhidrotic ectodermal dysplasia is a rare condition characterized by underdeveloped ectodermal structure including the skin, teeth or skin appendages. The patient has characteristic feature of anhidrosis, hypotrichosis and defective dentition. We experienced a case of hereditary anhidrotic ectodermal dysplasia in a l-month-old male infant who had unexplained recurring fever, anhidrosis and characteristic facial feature, so we established the diagnosis with clinical feature and skin biopsy.

PURPOSE: The purpose of this study was to analyze the histologic concordance of sonographically guided core needle biopsy for phyllodes tumors or fibroepithelial lesions with cellular stroma of the breast by comparing this with the outcomes of excision biopsy and to identify any sonographic features that are helpful to predict phyllodes tumors. MATERIALS AND METHODS: We retrospectively reviewed 60 breast masses that were diagnosed as phyllodes tumors (n = 43) or fibroepithelial lesions with cellular stroma (n = 17) on a sonographically guided core needle biopsy. The tumors were all subsequently excised by surgery. The sonographic features were compared between the phyllodes tumors and the non-phyllodes tumors according to the results of excision biopsy. RESULTS: By the results on excision biopsy, there were 48 (80%) phyllodes tumors and 12 (20%) non-phyllodes tumors. Phyllodes tumors were diagnosed at a rate of 90.7% (39/43) for the nodules with phyllodes tumors on the sonographically guided core needle biopsy, and at a rate of 52.9% (9/17) for the nodules with fibroepithelial lesions with cellular stroma on the sonographically guided core needle biopsy. On sonography, heterogeneous internal echotexture (58% vs. 17%, respectively, p = 0.0239), clefts (56% vs. 17%, respectively, p = 0.0331) and horizontal linear striations (71% vs. 33%, respectively, p = 0.0221) were significantly more frequent in the phyllodes tumors than that in the non-phyllodes tumors. CONCLUSION: Identification of a heterogeneous-internal echotexture, clefts and horizontal linear striations on sonography might help differentiate phyllodes tumors from non-phyllodes tumors.

PURPOSE: To evaluate MR characteristics of periosteal reactions and subperiosteal abscesses in osteomyelitis as compared with radiographs. MATERIALS AND METHODS: We retrospectively reviewed 28 patients(18 males, 10 females) with osteomyelitis. Nineteen patients underwent MR imaging with 0.5 T. We analyzed for morphologic patterns, intervals of appearance and disappearance of periosteal reactions after symptom onset. Twenty-three patients were confirmed by surgery and 5 patients by the radiologic findings, clinical and laboratory data. RESULTS: Periosteal reaction appeared as low signal intensity arc on the T1- and T2-weighted axial images. In 3-7 days after symptom onset, periosteal reactions and subperiosteal abscesses were noted on MR imaging, and only two of eleven patients were noted in radiographs. Periosteal reactions of 8-14 days after symptom onset were demonstrated in all of 13 patient on MR, and 9 on plain radiographs. All patients with 2 weeks after symptom onset showed perioste.al reaction in plain film and MR. The periosteal reactions persisted until approximately 2 to 3 months after treatment on follow up radiographs. CONCLUSION: Periosteal reactions in osteomyelitis are detected on the MR imaging earlier than plain film. MR is valuable in detecting subperiosteal abscess which is not appecent in simple radiographs. Periosteal reactions can be seen on MR in 3 days after symptom onset and persist for 2-3 months after treatment.

Ureterocele, congenital dilatation of the terminal or intramural portion of the ureter, may be classified as either simple or ectopic and has a broad spectrum of presentation, anatomy and treatment must be individualized. From February, 1986 to March, 1994, our experiences with 8 single system ureteroceles and 12 duplex system ureteroceles were reviewed. Their presentation, radiographic findings, operative management and postoperative results were discussed. The patients in this series were distribution from 1 year old to 66 years old and the male and female ratio was 4:16. The most presenting symptom was flank pain, affecting 7 cases, and ureterocele was associated with ureteral stone: 7 cases, VUR: 2 cases, renal cyst: 1 case, and IgA nephropathy:1 case. In 8 cases of single system ureterocele, Transurethral incision(TUI) of ureterocele in 1 case, ureterocelectomy with ureteroneocystostomy in 3 cases were done. In 12 cases of duplex system ureterocele, TUI of ureterocele in 2 cases, heminephrectomy with partial ureterocelectomy in 2 cases were done. After operation was done, there was no evidence of complication. We conclude that the surgical approach to the problems associated with a ureterocele is modified by patient age, renal anomaly and the pathological condition of the lower urinary tract.

PURPOSE: The purpose of this study was to determine if the sonographic features of mammary fibromatosis had correlation with the pathologic findings. MATERIALS AND METHODS: We identified four cases of fibromatosis of the breast at our institution over a 10-year period. The patients were all women, and they ranged from 25 to 48 years of age (mean, 34.3 years). All four patients complained of palpable breast masses and were subsequently diagnosed with mammary fibromatosis. We retrospectively reviewed their imaging findings. RESULTS: Mammography obtained in one patient revealed architectural distortion. On sonography, all four cases showed spiculated, irregular, hypoechoic masses that could not be differentiated from malignant lesions. After surgical excision and vacuum-assisted biopsy of the masses in four patients, there was no recurrence on clinical or sonographic follow-up over a 13-36 month period. CONCLUSION: Although mammary fibromatosis is a very rare condition, it should be included in the differential diagnosis when an un-calcified, spiculated, irregular and hypoechoic masses are encountered on breast sonography.

PURPOSE: To evaluate the ultrasonographic features of nonlactiferous breast abscess. MATERIALS AND METHODS: We retrospectively reviewed ultrasonograms of 21 cases with surgically and clinically proved nonlactiferous breast abscess. The cases included 17 cases of acute or chronic inflammation and 4 cases of tuberculosis. RESULTS: Location of the lesion was subareolar in 15 cases and peripheral in 6. Mean anteroposterior/transverse diameter ratio was 0.49. Internal echogenicitiy of the lesion was variable, with heterogeneous mixed-echoic echotexture in 18 cases and homogeneous hypoechoic in 3. Margin of the lesion was irregular in 18 cases(85.7%) and posterior sonic enhancement was observed in 17 cases(81%). There were also noted obliteration of adjacent superficial fascia, localized skin thickening, and sinus tract or ductal ectasia in 19(90.5%), 9 (42.9%), and 9(42.9%) cases respectively. CONCLUSION: Major ultrasonographic findings of nonlactiferous breast abscess was subareolar located, variable shaped mass with posterior enhancement. Additional findings were fistular formation, loss of superficial fascia, and axillary lymphadenopathy.
