Hemorragia Intracerebral Imprevisible en un Hombre Joven: La Importancia de la Tomografía computarizada craneal post-mortem / Unpredictable Intracerebral Hemorrhage in a Young Male: The Importance of Post-Mortem Cranial Computed Tomography

La muerte súbita es aquella que ocurre dentro de las 24 horas posteriores al inicio de los síntomas y se caracteriza por ser clínicamente inexplicable, inesperada y repentina. Debido a la naturaleza de la muerte súbita, no es posible llegar a un diagnóstico preciso sin una autopsia. En esta comunicación breve, evaluaremos el caso de un empleado de crucero de 33 años, sin historial médico/farmacológico previo, el cual falleció súbitamente mientras reposaba en su camarote. Debido a las sospechas iniciales de una posible muerte causada por una sobredosis de cocaína, se le realizó un panel toxicológico abarcador el cual resultó negativo. Empero, una tomografía computarizada (TC) craneal sin contraste revirtió la hipótesis inicial y la autopsia neuropatológica -sorpresivamente- confirmó que la verdadera causa de muerte fue la ruptura de un aneurisma sacular desconocido en el polígono de Willis.

Sudden death occurs within 24 hours after the onset of symptoms and is characterized by being clinically inexplicable, sudden, and unexpected. Due to the nature of sudden death, it is not possible an accurate diagnosis without performing an autopsy. In this brief communication, we will evaluate the case of a 33-year-old cruise employee, with no prior medical/pharmacological history, who suddenly died while resting in his cabin. Due to initial suspicions of a possible cocaine overdose death, a comprehensive toxicology panel was performed, although yielding a negative result. A cranial computed tomography without contrast reversed the initial hypothesis and the neuropathological autopsy -surprisingly- confirmed that the true cause of death was the rupture of an unknown saccular aneurysm in the Circle of Willis.

Bone tumors of mixed origin: osteoliposarcoma and osteo-rhabdomyosarcoma

One: A complete perusal of the literature velealed twenty cases of primary liposarcoma of bone acceptable as such to the authors. These were tabulated as to location and age. 2. Eight cases of osteo-liposarcoma, primary in bone, were encountered in the literature and an additional case was reported by the authors. 3. The authors described for the first time in the literature a new primary tumor of bone of mixed origin: osteo-rhabdomyosarcoma. After careful perusal of the literature they added three additional casesÑ two cases56, 58 previously reported as primary rhabdomyosarcoma of bone, which on carreful evaluation of the radiographs in said publications and the paucity of microphotographs they considered to be osteo-rhabdomyosarcomas, and the other case, previously reported as malignant mesenchymoma of the sternum following radiotherapy for breast cancer. 4. The authors prefer to classify these tumors (osteo-liposarcoma and osteo-rhabdomyosarcoma) as "Tumors of Mixed Origin" and not as "Malignant Mesenchymomas". 5. A complete review of the literature revealed 219 reported "with additional mesenchymal component", among which only nine (9) contained a bonafide rhabdomyosarcomatous component. The rest exhibited other mesenchymal tumors as osteogenic sarcoma, fibrosarcoma, malignant fibrous histiocytomas, angiosarcoma, and undifferentiated sarcoma. The authors recommend to continue classifying these tumors as chondrosarcomas with additional mesenchymal component or even as ...
