ABSTRACT

PURPOSE: To investigate the interest of postmortem non-enhanced computer tomography (CT) for abdominal lesions in a forensic context of suspicions death and to list the different radiological cadaveric modifications occurring normally at abdominal stage, which must be known by non forensic radiologists in case of any postmortem exam. MATERIALS AND METHODS: 30 cadavers have been submitted to a body CT-scan without injection of contrast material. CT exams were reviewed by two independent radiologists and radiological findings were compared with forensic autopsy data. RESULTS: False positive CT findings included physiological postmortem transudates misdiagnosed with intra-abdominal bleedings, and putrefaction gas misdiagnosed with gas embolism, aeroporty, aerobily, digestive parietal pneumatosis. Incidentalomas without any role in death process were also reported. False negative CT findings included small contusions, vascular thromboses, acute infarcts foci, non radio-opaque foreign bodies. Normal cadaveric modifications were due to livor mortis and putrefaction, and are seen quickly (some hours) after death. CONCLUSION: The non forensic radiologist should be familiar with the normal abdominal postmortem features in order to avoid misdiagnoses, and detect informative lesions which can help and guide the forensic practitioner or the clinical physician.

ABSTRACT

Cranial and spinal trauma are a frequent cause of disability in the general population. Post-traumatic paraplegia or quadriplegia or hemiplegia from vascular injury (CVA) can lead to early complications (respiratory, cardiovascular, urinary, cutaneous, infectious...) that may have an impact on the immediate prognosis. Neurologic and orthopedic complications occur later and further impair the quality of life of patients. Orthopedic complications include: neurogenic paraosteoarthropathy (NPOA) or neurogenic osteoma or myositis ossificans (NMO). The nomenclature currently in use is NMO; Osseous complications: osteoporosis and secondary insufficiency fractures; Joint complications: degenerative arthropathy and stiffness; Overuse mechanical complications; Muscular complications; Infectious complications: arthritis and myositis complicating skin ulcers and bed sores. The purpose of this paper is to describe these neuro-orthopedic complications and review their imaging features.

ABSTRACT

Spasticity, a component of the pyramidal syndrome, characterized by increased tonic stretch reflexes and hyperactive deep tendon reflexes, occurs in patients with central nervous system lesions (stroke, brain or cord injury, multiple sclerosis, cerebral motor impairment). The implementation of standard procedures (patient positioning, increased examination time, turning off certain devices before MR imaging) allows the acquisition of high quality examinations in spastic patients. Worsening spasticity in a handicaped patients is due to an irritative process (deep seated infection, fracture, syrinx...) usually detectable with imaging. Ultrasound or CT guided injections of botulinum agents provides radiologists with the opportunity to further participate in the management of spastic patients.

ABSTRACT

The imaging evaluation of post-traumatic spine and cord injuries is part of the global management of chronically handicapped patients. Diagnosis and follow-up MR imaging of cord lesions allows differentiation of static lesions from progressive lesions that could require surgical intervention. Follow-up CT imaging is helpful in the evaluation of spine lesions to distinguish between late complications (deformity, malunion, pseudoarthrosis, complications related to surgical hardware) and lesions secondary to the handicap (neurogenic spinal arthropathy).
