Recurrent Lhermitte-Duclos disease in a child. Case report.

A case of recurrent Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum) in a child is described with a summary of the clinical presentation and associated malformations, and a review of other cases reported in the literature. The histological examination and electron microscopic findings, with special reference to the cytological changes found during evaluation of the recurrence, are presented. Theories regarding the pathogenesis of Lhermitte-Duclos disease are reviewed.

Giant congenital cellular blue nevus of the scalp of a newborn with an underlying skull defect and invasion of the dura mater.

A case of a giant congenital cellular blue nevus of the scalp of a newborn with focal areas of malignant melanoma is presented. The nevus was associated with focal invasion of the underlying soft tissues, calvarium, epidural space, and dura mater. The later appearance of pigmented nevi in the submandibular region, sternocleidomastoid muscle, and testicular hydrocele raises the question of future metastases despite the nonmalignant microscopic appearance. Therapy consisted of total excision with cranioplasty and rotation and split skin grafts after temporary closure with silicone mesh.

Bilateral upper extremity paralysis (Bell's cruciate paralysis) from a gunshot wound to the cervicomedullary junction.

Cruciate paralysis is characterized by midline involvement of the rostral portion of the pyramidal decussation, resulting in paralysis of the upper extremity without lower extremity involvement. The neuroanatomical basis is the more rostral and medial decussation of the upper extremity motor fibers in the medulla compared with the more caudal and lateral decussating fibers of the lower extremity at the lower boundary of the cervicomedullary junction. We believe this to be the first reported case of Bell's cruciate paralysis caused by a gunshot wound to this region. The neuroanatomical basis and the mechanisms that produce this unique clinical entity are discussed.

Anatomical study of the superficial temporal artery.

Fifty consecutive human autopsy specimens were studied to determine the suitability of the superficial temporal artery (STA) for use in microvascular anastomoses. Ten variations of the STA were found. The STA at the zygoma averaged 2.2 mm in outside diameter. The STA averaged 31.7 mm from the zygoma to its bifurcation, where the average outside diameter was 1.9 mm. Eight per cent of the specimens had no bifurcation, and 92% had at least one branch in a frontal or parietal distribution that was greater than or equal to 1 mm. A suitable frontal branch (i.e., greater than or equal to 1 mm in diameter and greater than or equal to 70 mm in length) was found in 90% of the specimens, and a suitable parietal branch was found in 71%. Six specimens (12%) had an additional branch, all of which were of suitable length and diameter. Eight per cent of the specimens lacked a vessel suitable for microvascular anastomosis.

Transcallosal approach to the contralateral ventricle. Technical note.

Recent experience with an intraventricular arteriovenous malformation (AVM) demonstrated the usefulness of a transcallosal approach to the contralateral ventricle. Although this technique provides excellent exposure, its application has not been stressed in the literature. A brief description of the technique and its value is presented.
