    Notes: Abstract A case of abdominal actinomycosis is described in a woman with recurrent right lower abdominal pain and low-grade fever without history of appendectomy. Past history included the use of an intrauterine device (IUD) until 10 years before manufestation of these symptons. We followed up the patient, via diagnostic imaging, for 7 months. On initial barium enema, a polypoid lesion was visualized at the bottom of the cecum and there was constriction of the sigmoid colon; the appendix was not seen. Seven months later, poor extension at the cecum, severe constriction in the sigmoid colon, and narrowing of the terminal ileum were also visualized. On computed tomography (CT), the lesion was initially localized only in the ileocecal region adjacent to the sigmoid colon. After 7 months, the lesion had infiltrated adjacent anatomic components and showed direct infiltration of the pelvic space. Differential diagnosis was difficult, as it was not obvious whether this was a pelvic abscess due to inflammation or appendiceal carcinoma. Laparotomy was performed. Macroscopically, the lesion was not limited to the ileocecal region, but involved the right ureter, tubes the Fallopian and ovary, bladder, psoas muscle, and abdominal wall. Pathology findings showed, chronic inflammatory tissue with evidence of actinomycosis. Although previous reports have described a lack of specific findings in this disease. When actinomycosis is suspected, CT is recommended to define its extent.

    Notes: Abstract Background: It is important to reduce local residual cancer to avoid local recurrence after breast conserving treatment. We therefore tried to detect the Backgroundintraductal components and small invasive foci of breast cancers by contrast-enhanced helical computed tomography (CE-CT). Methods: In 122 women whose breasts were examined by CE-CT preoperatively, intraductal spread detected on ultrasound (US), mammography (MMG), and CE-CT, and extensive intraductal components (EICs) detected by histological examination were analyzed for correlations among the extent and subtypes of intraductal components, and deviations in tumor size. Results: EICs were present in 44 patients. The sensitivities of EIC detection by US, MMG, and CE-CT were 35%, 61%, and 88%, respectively, and the corresponding specificities were 83%, 86%, and 79%, respectively. The sensitivities of detecting EIC and small invasive foci were 34%, 57%, and 91%, respectively. In 5 patients, EIC could only be visualized by CE-CT. The median deviation of the size of intraductal spread revealed by CE-CT from pathological EIC was 0.0 cm (range + 3.0 to − 1.7 cm. Conclusions: CE-CT is useful for visualizing intraductal spread and small invasive foci of breast cancer.

    Contrast‐enhanced computed tomography detection of occult breast cancers presenting as axillary masses (1999)

    Notes: Abstract Some non‐palpable breast cancers presenting as axillary metastases (occult breast cancer, OBC) are not clinically detectable by either mammography (MMG) or ultrasonography (US). We performed contrast‐enhanced computed tomography (CE‐CT) in order to locate the primary tumors in five cases of OBC and succeeded in locating all of them.
