Abdominal complications of chemotherapy in pediatric malignancies: imaging findings.

Objective: To describe the imaging findings of abdominal complications caused by chemotherapy in pediatric cancer patients.

Subjects And Methods: Radiology studies of 243 patients treated in our Children Cancer Center were reviewed, 164 of whom had abdominal studies. Medical records of 54 patients with abnormal imaging findings were studied.

Abdominal manifestations of multiple myeloma: a retrospective radiologic overview.

Background: Abdominal manifestations of multiple myeloma (MM) are rare. Herein, the authors study the radiologic characteristics of such involvement because these findings are usually missed by the radiologist and oncologist.

Patients And Methods: We retrospectively reviewed the medical records of 202 patients with MM treated at our institution.

Generalized dysplasia epiphysealis hemimelica with contralateral sacro-iliac joint involvement.

Dysplasia epiphysealis hemimelica (or Trevor's disease) is a rare developmental bone dysplasia characterized by benign osteocartilaginous overgrowth involving one or multiple epiphyses, usually of a single lower extremity. It is classified as localized form, classical form (most common), and generalized form. In this report we describe a case of generalized form of dysplasia epiphysealis hemimelica with involvement of the contralateral sacroiliac joint, which is an extremely rare presentation.

Left-sided cervical aortic arch associated with pseudocoarctation, aneurysm formation, and anomalous left brachiocephalic vein: appearance on MDCT and MR angiography.

Cervical aortic arch (CAA) is a rare congenital aortic anomaly. It can be associated with several cardiovascular abnormalities including aortic aneurysm, valvular disease, and pseudocoarctation. In this report, we present a case of CAA with combined association of both aneurysm formation and pseudocoarctation.

Imaging findings of familial Mediterranean fever.

Purpose: The aim of this study was to study the imaging findings of familial Mediterranean fever (FMF).

Materials And Methods: We performed a retrospective review of the medical records and imaging studies of 38 patients with proven FMF, diagnosed between 1992 and 2002.

Results: The most common clinical manifestation was recurrent peritoneal attacks with abdominal pain (76.

Heterozygous prothrombin 20210G/A mutation, associated with hyperhomocysteinemia, and homozygous methylenetetrahydrofolate reductase 677C/T mutation, in a patient with portal and mesenteric venous thrombosis.

We herein report a 34-year-old man who was investigated for severe abdominal pain. Portal vein thrombosis (PVT) and mesenteric vein thrombosis (MVT) were diagnosed. An association with two predisposing factors for thrombosis was noted: (1) heterozygous factor II 20210G/A mutation and (2) homozygous methylenetetrahydrofolate reductase (MTHFR) 677C/T mutation with hyperhomocysteinemia.

Imaging of hepatic cystic lesions.

Cystic lesions of the liver are a common finding and the differential diagnosis is wider than often considered. Awareness of the radiologic key features allows a correct presumptive diagnosis in a lot of cases. Diagnostic accuracy is increased when combining the characteristic radiologic features to the clinical history and laboratory findings as summarized in Table I.

Imaging of common benign solid liver tumors.

The imaging modalities currently used for radiologic detection and characterization of hepatic neoplasms include color Doppler sonography, helical computed tomography (plain, biphasic enhanced CT), magnetic resonance imaging (plain, gadolinium enhanced MR), radionuclide scintigraphy (Technetium RBC, sulfur-colloid, IDA scan), angiography, and image-guided percutaneous needle biopsy. MR imaging is probably better at characterizing lesions than CT scan, but the latter remains the modality of choice at many institutions due to the speed of acquisition and good contrast resolution inherent in the technique. Each of these modalities is useful, but accurate lesion detection and specific radiologic diagnosis is most often made in many patients with typical imaging features using a combination of examinations rather than with a single modality.

Biliary fascioliasis: case report and review of the literature.

Hepatobiliary parasitic diseases are rare in Lebanon. We recently encountered biliary fascioliasis in a Lebanese native. The clinical and laboratory findings were nonspecific.
