    Notes: Abstract The case of a 13-year-old girl with striking carpal and tarsal osteolysis (sporadic occurrence) is reported. MRI confirmed the total absence of carpal bones and medial tarsal bones. Dense fibrocollagenous tissue replaced the spaces left by the resorbed bones. Arteriography showed occlusion of the radial artery at the level of the physis of the distal radius with increased tortuosity of the ulnar artery. There was no major vascular occlusion in the foot except for some indistinct and blurred tarsal branches of the anterior tibial artery.

    Notes: Abstract Radionuclide imaging of benign soft-tissue tumors sometimes associated with extremity enlargement (7 patients) and/or osteodysplasia (6 patients) has demonstrated, in a total of 18 patients, several differentiating patterns of accumulation of Technetium-99m diethylene triamine pentaacetic acid (Tc-99m DTPA). Early imaging (within 15 min) as well as later imaging (one-half hour to 3 hours following the intravenous injection of the radiopharmaceutical) has shown that fatty tumors (lipomas, lipoblastomas, fibrofatty tissue) do not concentrate the isotope. Neurofibromas display gradual intensification of their radioactive content, while hemangiomas differ in their scintigraphic pattern depending on their histologic composition. Purely capillary hemangiomas have transient early intense activity while purely cavernous hemangiomas display no early activity but are well visualized on delayed scintigraphic images. Mixed hemangiomas display combined imaging characteristics of both capillary and cavernous types with the predominant pattern dependent upon the predominant histology. Aggressive fibromatosis exhibited an early fleeting display of intense radioactivity.

    Notes: Abstract We report a patient with a mild form of the Baller-Gerold syndrome (craniosynostosis-radial aplasia syndrome). The patient, a 3-year 3 month-old boy, has trigonocephaly with bilateral absent radii and thumbs. His growth parameters and psychomotor development have been normal. No visceral anomalies were found. This patient represents a new case of the rare mild form of the syndrome.

    Notes: Abstract Bilateral radiographic irregularities and deformities of the proximal femoral epiphyses are features of both multiple epiphyseal dysplasia and bilateral idiopathic avascular necrosis. In the past these entities have been difficult to differentiate. This report documents radiographically the occurrence of avascular necrosis in 10 patients with multiple epiphyseal dysplasia by recognizing the superimposition of sclerosis and subchondral fissuring on pre-existing symmetrically irregular proximal femoral ossification centers. Scintigraphic (photopenia) or magnetic resonance (loss of signal) criteria of avascular necrosis confirm its added presence and help to establish an imaging scheme to identify avascular necrosis superimposed on multiple epiphyseal dysplasia.
