Fifty patients were hospitalised at Vientiane during May and June 1975. Infection was caused by consumption of pork meat (som-mou, lap mou and lap leuat). After an incubation period of 8 to 11 days intermittent diarrhoea followed by constant fever and orbital oedema occurred. Several days later diffuse myalgias occurred. Three patients presented neurological symptoms: left hemiplegia flexible paraplegia and limb paresis; these symptoms regressed spontaneously. 87% of the clinically suspected cases had specific serum antibodies (IFI, ID, IE). Hyperleucocytosis and hypereosinophilia were a constant factor. Anti-AH antibodies were detected by the Widal test. The histopathology characteristic of myositis was seen in the 12 muscle biopsies. Also observed was the precystic state of the larvae which is in agreement with the early timing of the samples which were obtained during the 3rd and 4rd week of infection.

To date, 271 cases of HTLV1-associated paraplegia have been observed in Martinique (French West Indies). The clinical picture consisted mostly in a spastic paraparesis or paraplegia with sphincter disturbances (80%) and lower limbs pains (60%). The severity of the disease appeared variable: after a mean disease duration of 6.5 years, 40% of the patients could walk without help, 35% used a single crutch, and 25% used a couple of crutches or were confined to a wheelchair. A variable neuromuscular component was observed in 70 cases (25.4%). In 38 cases, the peripheral signs (SIGNS) or the myositis were only mild. In contrast, 25 patients presented with severe amyotrophy evoking amyotrophic lateral sclerosis, and 7 other had features of dermatopolymyositis. Lastly, an extra-neural spreading of the disease was extremely frequent, including lymphocytic alveolitis (76%), sicca syndrome (69%) and more rarely uveitis, arthritis or vasculitis.

Heterotopic ossification is a benign, ectopic bone growth that develops in muscle and other soft tissue. The exact cause is poorly understood, but it is a rarely serious complication of soft tissue trauma. Its most common form, myositis ossifications traumatica, occurs as a secondary complication of direct muscle injury. However, other forms are less common and can result from specific pathologic conditions, such as spinal cord trauma and metabolic disorders. In patients who have had spinal cord injury and subsequent paraplegia, heterotopic ossification often results in ankylosis of the hip and a loss in range of motion. Ectopic ossification occurs below the injury site, and, although the specific muscle groups can vary, it usually involves those for which the origin and insertion involve the anterior pelvis and proximal femur. In dried bone, heterotopic ossification can appear as a smooth, irregularly shaped benign tumor of mature bone, extending from the surface but not invading the cortical bone. These tumors range in size from a few millimeters to several centimeters. Because heterotopic ossification is often associated with specific types of injuries, it has a unique anthropological use in forensic cases.

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.

Hypereosinophilic syndrome is a rare disorder of the hematopoietic system. The disease is characterized by continuously high number of eosinophils (>1.5 x 10(9)/L) for more than six months. Other possible causes of hypereosinophilia, such as allergic and parasitic diseases, malignant disease, Churg-Strauss disease and infection should be eliminated. The most common manifestations of hypereosinophilic syndrome are pulmonary, skin, gastrointestinal, cardiac difficulties and neurologic lesions. Numerous neurologic lesions have been described, in particular of the central and peripheral nervous systems. Review of the literature revealed the following to have been recorded so far: mononeuritis multiplex, sensory polyneuropathy, radiculopathy, myalgia, myositis and perimyositis, neuropathy, ataxia, paraplegia, ophthalmologic abnormalities, optic neuritis, hemiplegia-hemiparesis, spasmodic quadriplegia, seizures, meningitis, cerebral infarction, organic psychosyndrome, other mental changes, stroke, temporal arteritis, leptomeningeal dissemination, memory deficits and dysarthria.

Myositis Ossificans (MO) is an unusual pathological entity still largely unknown, characterized by dystrophic calcification leading to heterotopic ossification of intramuscular connective tissue. The masticatory muscles are exceptionally involved. Four distinct types of myositis ossificans have been described: MO Progressiva, which is a genetic disorder involving several muscular groups; MO Circumscripta, limited to a single muscle and generally due to calcification of an intramuscular haematoma following severe trauma and progressive ossification; MO Pseudo-malignant limited to soft tissue and not associated to any trauma; MO associated to paraplegia. A case of circumscribed myositis ossificans of the masseter muscle in a 62 years-old woman is reported.
