Apparent or true neonatal hip dislocation? Radiologic differential diagnosis

A case of neonatal separation of the proximal femoral epiphysis secondary to obstetric trauma is presented. The radiologic differential diagnosis, as in other cases of neonatal dislocation of the hip, included congenital and septic dislocation of the hip and epiphyseal separation - so-called apparent dislocation. When clinical and laboratory signs are minimal or equivocal, x-ray films and, in difficult cases, contrast arthrograms are needed for an accurate diagnosis of neonatal dislocation of the hip.     

Skeletal dysplasia,intracerebral calcifications,optic atrophy,hearing impairment,and mental retardation: Nosology of dysosteosclerosis

A girl who presented at 3 months of life with severe developmental delay, blindness, and hearing impairment was found to have intracerebral calcifications. Skeletal films showed craniotubular bone modeling consistent with dysosteosclerosis. The nosology of this disorder is discussed. © 1992 Wiley-Liss, Inc.     

Traumatised ischial apophysis (report of six cases)

Six boys with traumatic ischial apophysis are reported. Two cases were diagnosed as stress apophysis and four as apophyseolysis. Two of our patients were referred to the hospital as malignant bone tumours--Ewing sarcoma and osteosarcoma.     

SMN2‐deletion in childhood‐onset spinal muscular atrophy

We report a 27‐year‐old man with an apparently new syndromic form of progressive erosive arthropathy and contractures of small and large joints associated with mild epiphyseal changes, normal vertebrae, and generalized osteopenia. The patient had a characteristic craniofacial appearance, dermatological abnormalities, and normal intelligence. The head was large with frontal bossing. The face was elongated with malar hypoplasia, thin upper lip, prominent lower jaw, high arched palate, dental malocclusion, and prominent ears with absent ear lobules. Dermatological abnormalities included malar erythema and facial telangiectasia together with multiple nevi and lentigenes all over the body. Pseudorheumatoid arthropathy, spondyloarthropathy, and Borrone dermatocardioskeletal syndrome were considered in the differential diagnosis and were excluded. Also, no similar cases have been found in POSSUM or the London Dysmorphology databases. © 2001 Wiley‐Liss, Inc.     

Dracunculosis or Medina worm filariasis. Apropos of 2 cases

We report two patients with calcified Medina worms. With the considerable increase in international travel and exchange, it is important that radiologists in non-endemic areas be familiar with this type of parasitic calcification.     

Hyperplastic callus formation in osteogenesis imperfecta type V: follow-up of three generations over ten years

Hyperplastic callus (HPC) formation is a prominent feature of osteogenesis imperfecta (OI) type V; however, little is known about its long-term outcome. In this case report we describe the occurrence, appearance and course of a femoral HPC in a patient with OI type V during 10 years of follow-up. Radiographs of HPC in this child were compared and contrasted with HPC formation in the femur of his father and paternal grandfather, who also were affected with OI type V. This case report makes it clear that HPC can lead to significant morbidity, not only in the acute phase but also long term as a result of residual alteration in bone architecture.
