Bone lesions on radiographs of newborns often suggest congenital infections. Skeletal roentgenograms are recommended in the evaluation of suspected congenital syphilis, but bone lesions have been recognized in other congenital infections. We report the case of an infant with hydrops fetalis secondary to congenital parvovirus B19 infection who was found to have bone lesions in multiple long and ...

the aim of this study was to assess the value of 99mtc-hexakis-2-methoxyisobutylisonitrile (mibi) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. methods: the scintigraphic findings for 84 patients were compared with the surgical and histologic findings. each patient underwent three-phase bone scan with 99mtc-methylene diphosphonat...

Up to 90% of patients with multiple myeloma develop bone lesions. The lesions are purely osteolytic because of increased osteoclast activity and markedly suppressed or absent osteoblast activity. The "gold standard" for imaging myeloma bone lesions is the metastatic bone survey. However, plain radiographs are relatively insensitive and can only demonstrate lytic disease when 30% of trabecular b...

RANULOMATOUS LESIONS have been found iii paraffin sections nlade from particles of bone marrow removed by aspiration from patients w’it-h tuberculosis, histoplasmosis, brucehlosis, sarcoidosis, infectious mononucleosis, malignant lymphomas or miscellaneous and indeterminate disorders.19 In a previous paper,4 I discussed the significance of granulomatous lesions foiits(l in sections made from bo...

We present a system for computer aided diagnosis of bone tumors in the facial skeleton. There are many diierent lesions with ra-diographic manifestation in the jaws. Our system helps performing the diierential diagnosis of these. The input is a digitized orthopantomo-graph (OPG) in which the user marks the position of the lesion with a single mouse click. An active contour model then automatica...

Cutaneous presentation revealing acute myeloid leukemia (AML) is rare, and the prognosis poor. We report a case of an 11-month-old male who presented with cutaneous lesions present as diffuse purplish papulo-nodular lesions, M5 leukemia. Skin biopsy immunohistochemical examination, combined routine blood analysis bone marrow contributed to early diagnosis. However, despite intensive chemotherap...

OBJECTIVE To evaluate musculoskeletal involvement in paracoccidioidomycosis at computed tomography. MATERIALS AND METHODS Development of a retrospective study based on a review of radiologic and pathologic reports in the institution database. Patients with histopathologically confirmed musculoskeletal paracoccidioidomycosis and submitted to computed tomography were included in the present stu...
