Adenomyoepithelioma is very rare. Because of its rarity, adeonomyoepithelioma may present a diagnostic challenge to the radiologists and there is a little information on the diagnosis and treatment of this condition. I report on two patients with benign and malignant adenomyoepitheliomas which represent breast masses on mammograms and ultrasonograms. The diagnosis was confirmed by immunohistochemical study of the resected specimens.

PURPOSE: To assess relative signal intensity changes in frontal and occipital white matter with age, as seenon T2 weighted axial MR images. MATERIALS AND METHODS: Thirty eight normal adults (20-29 years old) and 114children (0-11 years old) were investigated. All had nonspecific neurologic symptoms and their MR images, obtainedusing a 1.5T system (Signa, GE Medical Systems, Milwaukee, U.S.A), appeared to be normal. The signal intensitiesof frontal and occipital white matter were evaluated on T2 weighted axial images at the level of the foramen ofMonro. When the signal intensity of white matter was higher than that of gray matter, grade 0 was assigned ; whenthe opposite situation pertained, this was graded I_III. Grade I indicated that the signal intensity of occipitalwhite matter was lower than that of frontal white matter ; grade II, that the signal intensity of white matter ofboth lobes was similar. When the signal intensity of frontal white matter was lower than that of occipital whitematter, grade III was assigned. We divided the children's age by six months before 2 years of age, and by one yearafter 2 years of age, and then determined grade according to age, age distribution according to grade, and theages at which signal intensities were similar to those of adults. RESULTS: All 38 adults showed a grade IIIpattern ; this grade was apparent as early as 1.5 years of age and by 3 years of age, it was seen in over 50% ofchildren. After 8 years of age, all children were grade III. The age distribution of grade 0 was 0-0.5 years ofage, for grade I this was 0.5-2 years of age, for grade II it was 1-7, and for grade III, it was 1.5-11. CONCLUSION: On T2-weighted MR images, the signal intensity of frontal white matter ultimately shows a lowersignal intensity than that of occipital white matter.

Primary pulmonary plasmacytoma (PPP) is extremly rare. Because of its rarity, PPP may present a diagnos-ticchallenge to the radiologists and there is a little information on the diagnosis and treatment of this condi-tion.We report on a patient with PPP presenting with a left hilar mass on chest radiograph and CT scan. The diagnosiswas confirmed by immunohistochemical study of the resected specimen.

Extranodal lymphoma presents in almost one-third of all non-Hodgkin lymphoma cases. The gastrointestinal tract, skin, and central nervous system are common sites of involvement, whereas the urethra and cervix are very rare. To the best of our knowledge, this is the first report on concurrent extranodal involvement of the uterine cervix and urethra. We report imaging findings of malignant lymphoma involving urethra and cervix concurrently in a 79-year-old female patient with literature review. The magnetic resonance imaging showed huge intermediate to high signal intensity mass on T2 weighted images and strong homogeneous enhancement in uterine cervix and periurethral area, but no surrounding architectural disruption.

Encapsulated papillary carcinoma (EPC) is an uncommon breast malignancy that is known to be indolent and associated with an excellent prognosis. However, there is a rare possibility of locoregional relapse or metastasis. Here, we present a case of recurrent EPC in the ipsilateral internal mammary lymph node (IMLN) that was detected in the postoperative magnetic resonance imaging with abbreviated protocol (AB-MRI). AB-MRI could facilitate the early detection of recurrent disease in the IMLN and may provide prognostic gain for such patients.

Small cell neuroendocrine carcinoma is a high-grade and poorly differentiated tumor typically presenting as primary pulmonary neoplasm. Extrapulmonary small cell carcinoma is rare. Primary small cell neuroendocrine carcinoma of the breast (SCNCB) is extremely rare, with an incidence of less than 0.1% of all breast cancers. Herein, we report imaging features of SCNCB incidentally diagnosed in a 58-year-old woman along with a literature review. The tumor was observed to be a round and circumscribed mass with rim enhancement, heterogeneous intra-tumoral enhancement, and peritumoral edema on MRI. The patient underwent breast-conserving surgery with adjuvant chemotherapy and radiation therapy. No tumor recurrence was observed during the 2-year follow-up visits after surgery.

Congenital urachal abnormalities are more common in children, but urachal cyst is more frequently seen in adults. Infection within a cyst produces significant symptoms, which may explain the fact that three times as many infected cysts as uninfected urachal cysts are detected in adults. We report here on a case of infected urachal cyst with a fish bone and also the fistular formation between the ileum and urachus in a 63-year-old male with a history of urinary frequency and a tender mass at the lower abdominal quadrant.

Inflammatory pseudotumors are tumor-like, benign lesions of uncertain pathogenesis and have most commonly been reported in the lungs. They occur rarely in the gastrointestinal tract and may cause small bowel obstruction due to intussusception or, less commonly, as an incidental finding on radiologic examination or screening endoscopy. We present a case of surgically proven jejunal intussusception caused by inflammatory pseudotumor.

Fetal abnormalities in central nervous system are now recognized more often with the increasing use of high-resolution prenatal sonography. Arachnoid cysts, because of their compression of adjacent brain tissue, may require neurosurgical intervention but otherwise they have a good long- term prognosis. The differential diagnosis of intracranial lesions is important to allow accurate counselling and also to optimize neonatal management. We report the two cases of fetal arachnoid cyst diagnosed with prenatal ultrasonography
