[Osteochondrosis dissecans of the hip in adults--differential diagnosis of free joint bodies--case report].

The causes of hip pain in adults can vary greatly. We present the case of a 44-year-old woman with recurrent hip pain over a period of years. Medical history and clinical examination did not provide any decisive information. The X-rays revealed a loose body in the cavity of the hip joint. The MRI scan made the following differential diagnosis plausible: osteochondrosis dissecans coxae, osteochondroma and chondromatosis. The final diagnosis of osteochondrosis dissecans coxae was confirmed by surgical dislocation of the hip as modified by Ganz and histological examination of the loose body. This case supports the importance of including rare lesions in the differential diagnostic work-up of joint pain. The advantages of the offset operation as modified by Ganz versus arthroscopy of the hip are outlined.

A preliminary evaluation of a dual crystal positron camera.

The whole-body positron camera PC2048-7WB, manufactured by Scanditronix AB, is based on a detection unit with two scintillating crystals on each photomultiplier tube. The design ideas are specified and a system description is given. Preliminary test results including spatial resolution, time resolution, scatter correction, homogeneity, sensitivity, and count rate linearity are presented.

Chondroid tumors arising from the meninges--report of 2 cases and review of the literature.

Chondroid tumors are rare intracranial tumors usually arising from the base of the skull. We present 2 cases of intracranial cartilaginous tumors with unusual location. In case 1, a 19-year-old woman, a chondroma of the falx cerebri with extensive secondary ossification was diagnosed. In case 2, a 30-year-old woman, a low-grade chondrosarcoma was resected from the right frontal lobe. Both patients showed an uneventful clinical course without evidence of disease 4.5 and 6 years after total extirpation. Our cases show that chondromas and low-grade chondrosarcomas of the dura and meninges usually occur in young adults with a good prognosis after complete extirpation.
