MRI of an unusual case of peduncular hallucinosis (Lhermitte's syndrome).
We report a case of peduncular hallucinosis (Lhermitte's syndrome), unusual in that there were no associated neurological signs and the symptoms persisted over many years. Magnetic resonance imaging demonstrated the typical midbrain lesion.

The use of ultrasound in the venous assessment of lower limb Klippel-Trenaunay syndrome.
Colour Doppler ultrasound was used to study the affected lower limbs of a group of patients with the Klippel-Trenaunay syndrome. The abnormal lateral venous channel characteristic of this syndrome was examined, together with its deep venous connections and deep venous patency established if present. Seventeen patients (18 limbs) were studied. Ultrasound demonstrated calf vein patency in 15 out of 17 limbs and deep venous patency from the popliteal vein to the inferior vena cava in 17 out of 17 limbs. Ultrasound was also effective in demarcation of the abnormal lateral venous channel, together with its deep connections (13 out of 16 limbs). We conclude that ultrasound is superior to the more established venographic techniques in the investigations of patients with the Klippel-Trenaunay syndrome. From this study, the deep venous aplasia said to occur in the condition would appear to be less common than previously thought.

Pictorial review: the imaging features of lower limb Klippel-Trenaunay syndrome.
The Klippel-Trenaunay syndrome is a rare mesodermal abnormality causing venous anomalies, cutaneous capillary naevi with bone and soft tissue hypertrophy of one or more limbs. In this pictorial review we illustrate the plain film, venographic, ultrasound and magnetic resonance imaging features of Klippel-Trenaunay syndrome affecting the lower limb.

Case report: prolonged contrast enhancement of the inner ear on magnetic resonance imaging in Ramsay Hunt syndrome.
There have been recent reports of enhancement of the inner ear in acute labyrinthitis on gadolinium enhanced magnetic resonance imaging (MRI). However, none has described persistence of enhancement beyond 6 weeks. We report a case of Ramsay Hunt syndrome with labyrinthitis, sensorineural hearing loss and facial nerve palsy in which marked enhancement of the inner ear structures was observed on MRI 6 months after the onset of symptoms. Enhancement on delayed or repeated imaging after a period of months does not exclude labyrinthitis from the differential diagnosis of the small intracanalicular acoustic neuroma, and care should be taken not to confuse them.

High-resolution ultrasound in the evaluation of the nonacute testis.
Ultrasound is the initial imaging modality used in the evaluation of the symptomatic testis. Ultrasound is painless and quick and supplements clinical examination of the testis. In this review, a range of testicular pathologies are discussed and sonographic examples illustrated. Particular attention is drawn to testicular microlithiasis and its relation to germ cell neoplasia and also to the sonographic features of epidermoid cysts that may allow testis-sparing surgery.
