    Description / Table of Contents: Zusammenfassung Von 21 Fällen von Whipplescher Krankheit in der Sammlung des Armed Forces Institute of Pathology zeigten 4 Fälle neurologische Symptome mit besonders ausgeprägten Hirnläsionen. Lichtmikroskopisch bestanden die Herde aus knötchenförmigen Anhäufungen von Makrophagen, deren Cytoplasma mit Hämatoxylin-Eosin eine charakteristische schwachblaue und nach Durchführung der Perjodsäure-Schiff-Reaktion eine stark rote Färbung zeigte. Elektronenmikroskopisch fanden sich in den Hirnläsionen Bacillen, die morphologisch den im Darm beschriebenen glichen und die auch dieselben Degenerationserscheinungen aufwiesen. Die Perjodsäure-Schiff-Reaktion färbt Kapselmaterial und Zellwände,die auch nach Untergang der Bacillen noch nachweisbar sind. Diese Beobachtungen werden als weiterer Beweis für die infektiöse Ätiologie der Whippleschen Krankheit angeführt.
    Notes: Summary Among the 21 autopsied cases of Whipple's disease on file at the Armed Forces Institute of Pathology, 4 had neurological symptoms and prominent involvement of the central nervous system, By light microscopy the lesions were composed of nodular aggregates of macrophages having cytoplasm that stained a distinctive pale blue with hematoxylin-eosin and bright red with the periodic acid-Schiff technique. By electron microscopy the cerebral lesions revealed bacilli morphologically identical to and undergoing the same sequence of degenerative changes as those observed in the intestine. The periodic acid-Schiff reaction stains the walls and the capsular material that persists even after intact organisms disappear. These observations further support the infectious nature of Whipple's disease.

    Notes: Summary Vein of Galen aneurysm (VGA) is an uncommon cerebral arteriovenous malformation which has not previously been reported in Turner's Syndrome. We report a case and present neuropathologic and radiographic results. There are few prior reports of neuropathologic examination in Turner's Syndrome.

    Notes: Summary By light microscopy, Hirano bodies are fusiform or spheroidal eosinophilic bodies, that are commonly observed in the hippocampi of the elderly and are especially numerous in patients with various dementias or degenerative diseases. Rarely, they have been demonstrated in other locations and even in animals. Ultrastructurally, the Hirano bodies are complex pleomorphic aggregates of intraneuronal fibrillary material found predominantly in the processes but occasionally in the perikarya. The Hirano bodies are assembled from multiple subunits, but occasionally in the perikarya. The Hirano bodies are assembled from multiple subunits, each consisting of two overlapping or intersecting expanses of parallel filaments. Depending on the plane of section and orientation, the subunit may appear as a lattice-work array of intersecting filaments, a row of regularly spaced punctate densities closely applied to a filament, or a broader feathery fibril. The subunits appear to be derived from the reorganization or precipitation of randomly dispersed finely filamentous material. Because of the diverse circumstance under which they are found, Hirano bodies are regarded as a non-specific manifestation of neuronal degeneration.

    Description / Table of Contents: Zusammenfassung Hirngewebe eines Falles von Pickscher Krankheit wurde licht-und elektronenmikroskopisch untersucht. Intraneuronale argentophile Picksche Körper wurden am zahlreichsten in den Pyramidenzellen des Hippocampus gefunden. Elektronenoptisch bestanden die Einschlußkörper aus einer Zusammenballung von körnigen Gebilden, die in einem unregelmäßigen Netz von vermehrten Neurofilamenten verstreut lagen. Viele eosinophile Hiranosche Körper fanden sich in nächster Nachbarschaft von Nervenzellen. Diese Körper bestanden aus verflochtenen Schichten von geperlten oder glatten Filamenten. Die mögliche Lokalisation der Hiranoschen Körper innerhalb von degenerierenden Axonendigungen wird diskutiert.
    Notes: Summary Brain tissue from an autopsied case of Pick's disease was studied by light and electron microscopy. Intraneuronal argentophilic Pick bodies were most numerous in the pyramidal cells of the hippocampus. By electron microscopy, these inclusions consisted of a conglomeration of granules enmeshed in an irregular network of proliferated neurofilaments. There were also multiple eosinophilic juxtaneuronal structures (Hirano bodies). By electron microscopy these consisted of interwoven sheaves of beaded and continuous filaments. The possible location of the Hirano bodies within degenerating axonal terminals is discussed.

    Description / Table of Contents: Zusammenfassung Diese Mitteilung betrifft Befunde eines ungewöhnlichen Falles von Pickscher Krankheit, der durch unikale Einschlußkörperchen mit kleinem eosinophilen Zentrum innerhalb der hämatoxylinophilen Pick bodies (Silberkugeln) gekennzeichnet war. Diese Gebilde werden mit anderen Einschlüssen verglichen, die man bei der Pickschen Krankheit und bei Erkrankungen des motorischen Neurons findet.
    Notes: Summary This report presents findings from an unusual case of Pick's disease that was characterized by unique compound inclusion bodies consisting of a small eosinophilic core within the hematoxylinophilic Pick bodies. These structures are compared to other inclusions observed in Pick's disease and motor neuron disease.

    Notes: Summary This report describes an unusual plexiform neurofibroma from a child with von Recklinghausen's disease that was characterized by the presence of numerous aberrant tactile corpuscles in both the original and recurrent tumor. The individual corpuscles appeared to be composed of combination of a Pacinian exterior and a meissnerian interior. This neoplasm is discussed in relation to previous reports of Pacinian neurofibromas.

    Notes: Summary Two older patients with Down's syndrome and widespread neurofibrillary tangles and senile plaques were studied by light and electron microscopy. The ultrastructural demonstration of twisted tubules verified the assumption that the tangles encountered in these patients were Alzheimer's neurofibrillary tangles. Despite the morphological evidence of Alzheimer's disease, neither of these patients were clinically demented.

    Notes: Summary “High spinal” (cervical and upper thoracic) dysrhaphism usually involves either a meningocele or a dermal sinus tract. These high spinal lesions can have a complex intradural anatomy at the level of the lesion (as this case reports) and are associated with an increased incidence of lower spinal occult dysrhaphic anomalies. It is therefore recommended that patients with “high spinal” dysrhaphism undergo radiological evaluation of the entire spine to identify those patients with intradural anomalies, define the anatomy for surgery, and investigate the lower spine for associated occult anomalies.
