Granulocytic sarcoma. Cranial and breast involvement.

The term granulocytic sarcoma designates an infrequent solid tumor composed of aggregates of immature granulocytic precursors in extramedullary sites. The lesion generally occurs either during the natural course of acute myelogenous leukemia or after a remission has been achieved; however, it may rarely represent the initial manifestation of the disease. We present radiologic features of cranial and breast involvement of granulocytic sarcoma in a 13-year-old female with acute myelogenous leukemia. The cranial lesion appeared nearly isointense with cortical gray matter on T1- and T2-weighted magnetic resonance (MR) images, and enhanced homogeneously after the injection of gadolinium. MRI showed a well-delineated lobulated mass in the left breast, which had a heterogeneous hyperintense signal and remarkable contrast enhancement.

Hippocampal malrotation with normal corpus callosum in a child with Opitz syndrome.

We present cranial magnetic resonance imaging (MRI) findings in a 6-year-old boy with Opitz syndrome. The electroencephalogram revealed epileptiform abnormalities in both frontal regions. MRI showed normal callosal development, but a rounded shape of the left hippocampus due to malrotation. The temporal horn was slightly dilated on the left side. These features were consistent with isolated hippocampal malrotation.

Virtual cystoscopy in the evaluation of bladder tumors.

OBJECTIVE: The objective of this study was to investigate the value of contrast material-filled virtual cystoscopy in the detection of bladder tumors. MATERIALS AND METHODS: Thirty-nine patients who had recent diagnosis or were followed up due to priory history of bladder tumor underwent virtual cystoscopy. After the intravenous injection of contrast medium, the bladder was examined with helical computed tomography (CT) scan. The data were transferred to a workstation for interactive navigation using surface rendering. Two radiologists independently interpreted the axial and virtual images, and discrepancies were resolved by consensus. The results of virtual cystoscopy were compared with the findings of conventional cystoscopy. RESULTS: Forty-nine of 54 bladder lesions detected with conventional cystoscopy in 33 patients were also shown on virtual images. On virtual cystoscopy, three of the seven lesions 5 mm or smaller in diameter could be identified. There were no false-positive findings. The sensitivity of the technique was 96.2% for polypoid tumors and 88.9% for sessile lesions. When axial and virtual images were evaluated together, the sensitivity rate increased to 94.4%. CONCLUSION: Bladder tumors can be diagnosed noninvasively using contrast medium-filled virtual cystoscopy. Evaluation of both the axial and virtual images increases the sensitivity of the technique.

Behçet's disease with right ventricle thrombus and bilateral pulmonary artery aneurysms--a case report.

Behçet's disease is currently recognized as a multisystemic disease that may present with vascular, cutaneous, pulmonary, neurologic, rheumatologic, gastrointestinal, and genitourinary manifestations. Despite this multiplicity, cardiac involvement and also the coexistence of bilateral pulmonary arterial aneurysms are rare. An interesting case is presented here with intracardiac thrombi and bilateral pulmonary arterial aneurysms that showed clinical regression with immunosuppressive therapy.
