ABSTRACT
A 12 year old male had a secondarily generalized epileptic seizure and a subsequent right hemiparesis with fasciobrachial predominance after a closed head injury. His seizures responded to antiepileptic drug therapy immediately. Computerized tomographic scanning and magnetic resonance imaging showed an acute infarct of the head of the left caudate nucleus, indicating the isolated occlusion of the left recurrent artery of Heubner and lateral lenticulostriate arteries. Pathologies leading to vasculitis and embolism were also looked for, but no finding of associated systemic disease could be disclosed. We present this case since posttraumatic infarction in the territory of the deep perforators such as recurrent artery of Heubner and lateral lenticulostriate arteries are exceptionally rare conditions especially in this age group.

Neurilemmomas of the hypoglossal nerve are uncommon neoplasms. A unique case of submaxillary hypoglossal neurilemmoma is presented with radiological and surgical results. Methods of diagnosis and differential diagnosis are discussed.

Improvement of long-term treatment with hemodialysis requires an optimized radiological differential diagnosis of bone changes associated with long-term hemodialysis. 85 patients with chronic renal failure on maintenance hemodialysis were examined. In a conventional radiographic skeletal survey of the whole spine, 22 patients (26%) had involved intervertebral discs. The site of predilection was the cervical spine followed by the lumbar spine; oligosegmental involvement was seen in nine patients. Eighteen patients with destructive non-infectious spondyloarthropahy had juxtaarticular cystic bony changes associated with the hip, shoulder and wrist. Bone biopsy in eight patients revealed amyloid as content of these cysts. The interrelation between the duration of preterminal and terminal renal failure on one hand and destructive bone changes in the spine and cysts on the other hand seems to point to destructive spondyloarthropathy as an important complication of renal insufficiency and dialysis.
