[Fatal encephalitis caused by a parasite].

Background: Encephalitis caused by a free-living amoeba is relatively rare and usually fatal. This is because the diagnosis is often made late and treatment is difficult.

Case Description: A 41-year-old patient with a previous history including kidney transplant was admitted with clinical symptoms of encephalitis.

[An adrenal incidentaloma in a trauma patient; a plea for expectant management].

An adrenal incidentaloma was detected in 45-year-old female driver after a car-versus-car collision. The mass, which had a diameter of 5.4 cm, was not a hormone-producing tumour, but because of its size laparoscopic adrenalectomy was performed 2 months later.

[Unavoidable surgical intervention in two women with severe actinomycosis during IUD use].

Extensive abdominal infections with Actinomyces were diagnosed in two women aged 35 and 33 years respectively, who suffered from the nonspecific symptoms fever and abdominal pain. These infections occur more often in women with an intrauterine device. Development of an abdominal mass with ureter or bowel obstruction may cause hydronephrosis and mechanical ileus.

Bone marrow ill-defined hyperintensities with tarsal coalition: MR imaging findings.

Introduction: To report the occurrence and pattern of ill-defined subchondral hyperintensities on Magnetic Resonance (MR) imaging in patients with talocalcaneal coalition (TCC).

Methods And Material: MR imaging of both feet was performed in 10 consecutive patients with 14 TCCs. There were eight males and two females with ages ranging from 9-52 years (mean 25 years).

Overuse and sports-related injuries of the ankle and hind foot: MR imaging findings.

Professional and recreational sporting activities have increased substantially in recent years and have led to a rise in the number of sports-related and overuse injuries. Magnetic resonance (MR) imaging has become an important tool for evaluating the lower leg for providing the necessary information for patient management and rehabilitation following this injury. The purpose of this essay is to give an overview of the MR findings of common overuse injuries and sports-related injuries to the bones and soft-tissue structures of the hind foot and ankle.

Assessing the subtalar joint: the Brodén view revisited.

We prospectively evaluated subtalar inversion stress views (Brodén view) with inversion stress views on helical CT in a group of 10 patients with unilateral instability. The contralateral, asymptomatic ankle was used as control. All patients were examined with inversion stress views on plain stress radiography and helical CT.

Posttraumatic subchondral bone contusions and fractures of the talotibial joint: occurrence of "kissing" lesions.

Objective: The objective of this study was to determine the presence and location of subchondral bone contusions, fractures, and "kissing" lesions of the talotibial joint after a sprain of the ankle shown on MR imaging.

Materials And Methods: We retrospectively reviewed the images of all consecutive patients who underwent MR imaging of the ankle after acute or recurrent sprain occurring between January and December 1997. The number and location of subchondral contusions or fractures revealed on MR imaging were recorded, and a comparison was made with the radiographs obtained for each patient.

Stress radiography and stress examination of the talocrural and subtalar joint on helical computed tomography.

The main objective of this study was to compare subtalar inversion stress views using the Brodén view with inversion stress views on helical computed tomography (CT). One of the drawbacks of routine radiography is the imaging of three-dimensional structures in a two-dimensional plane. We investigated whether the use of helical CT would lead to a more objective and clearer measurable method to determine the amount of tilt in the subtalar joint.

Magnetic resonance imaging of the femoral head to detect avascular necrosis in active rheumatoid arthritis treated with methylprednisolone pulse therapy.

Efficacious management of patients with avascular necrosis of bone (AVN) necessitates the identification of patients with a high risk of collapse of the femoral head. In this prospective study we imaged both hips of 10 patients with active rheumatoid arthritis, who were treated with methylprednisolone pulse therapy. MRI and conventional radiography were performed before MP-pulse therapy and 6 and 12 months thereafter.

Familial nonparasitic splenic cysts.

Only three times the occurrence of splenic cysts in siblings has been reported. This is the first report of a nonparasitic splenic cyst in mother and daughter. This improbable coincidence may perhaps give a better insight in the histogenesis of splenic cysts.

[Purulent parotitis in an infant].

A sibling was taken into hospital at the age of 3 weeks with an acute suppurative parotitis of the left parotid. Since birth, the child had suffered from recurrent infections. Her mother was known with recurrent furunculosis.
