Infection and miscellaneous
No full textMusculoskeletal infections contribute significantly to the disease burden in elderly people.
The diagnosis of infection in the older adult can be made more difficult by atypical or subtle presentations; however, early diagnosis and prompt treatment are vital to maximizing the probability of a positive outcome. Many specific infections are more common in diabetic patients, and some occur almost exclusively in them. In this chapter, we provide a review regarding the epidemiology, pathogenesis and imaging findings of spinal epidural infections, peripheral osteomyelitis, and septic arthritis in elderly patients with an emphasis on magnetic resonance (MR) imaging, which has greatly contributed to early diagnosis, thus allowing implementation of timely appropriate treatment. The role of imaging in distinguishing neuropathic osteoarthropathy and osteomyelitis in diabetic foot is also discussed in detail
Patologia traumatica vertebromidollare
No full textI dati epidemiologici di molti Paesi industrializzati pongono gli incidenti stradali al primo posto tra le varie cause dei traumi vertebro-midollari seguiti dalle cadute accidentali in ambito lavorativo e sportivo. La maggiore incidenza si riscontra nei maschi, con prevalenza per la fascia d’età compresa tra la seconda e quarta decade (1,2). Il trauma cervicale acuto rappresenta la lesione traumatica più seria e catastrofica per il midollo spinale tanto da essere responsabile del 20% circa dei decessi per incidente stradal
Tunneling Schmorl?s Nodes in an Elderly Woman Treated for Acute Lymphoblastic Leukemia.
No full textWe present a 70-year-old
woman with pre-B acute lymphoblastic
leukemia in whom serial imaging
studies showed the development
of multiple vertebral collapse,
and communicating superior and inferior
Schmorl’s nodes creating a
longitudinal channel (“tunneling”
Schmorl’s nodes) through the anterior
aspect of T12 to L3 vertebral bodies
of her osteoporotic thoracolumbar
spine. This was observed after
achieving complete remission of the
disease and during maintenance therapy.
The finding is felt to be secondary
to iatrogenic exacerbation of osteoporosi
A rare cause of Lumbar Radiculopathy: Spinal gas collection
No full textThe presence of gas in the intervertebral disk space, known as the vacuum phenomenon, is a relatively common radiologic finding, especially on computed tomographic investigation. In a few cases, the gas can be collected into the lumbar spinal canal and can also compress the nerve root. To date only seven cases of symptomatic lumbar radiculopathy caused by a bubble of gas are reported in the literature. The presence of gas inside a narrowed disk and the collection of gas in the spinal canal suggest a communication between the two structures. A case of lumbar radiculopathy caused by a collection of gas in the spinal canal provided the authors the opportunity to study this rare condition by magnetic resonance imaging. Magnetic resonance imaging had not been used before in the referred cases and proved conclusively the discal origin of the gas
Contro l"autorità" silenziosa dell'archivio. Pratiche archivistiche nell'arte contemporanea
No full textWhen contemporary artists rethink the modern paradigm of the archive, they produce inclusive and participatory counter-models which are never static, spaces of existential and socio-political resistance which take on the value of metaphors of memory and documentality. This essay examines the possibilities of the archive as a gesture of political and cultural subversion in artistic practice and theory
Calcifying pseudoneoplasm of the neuraxis: two case reports and review of the CT and MR findings
No full textCalcifying pseudoneoplasm is rarely encountered along the neuraxis, and only few cases have been reported to involve the spine. Its exact pathogenesis is unknown, and has been regarded as an unusual reactive process which must be differentiated from infection or malignancy. This rare entity carries a good prognosis after surgical resection. We report on the computed tomography and magnetic resonance imaging and diffusion-weighted features of calcifying pseudoneoplasm of the spine by describing two patients with involvement of the craniocervical junction, and thoracic spine
