Positron emission tomography: a false negative result in cystic encephalic mestastases from a small cell bronchial carcinoma.

Lung cancer represents one of the most common malignant diseases. Many investigations are used in the staging study including, most recently, PET. We present a case of cystic cerebral metastases (with no oedema) from a small cell carcinoma which were not detected by PET.

Las unidades médicas de corta estancia (UMCE) tienen un área de actuación preferente sobre una población en general anciana y pluripatológica cuyos diagnósticos más frecuentes suelen ser enfermedades de alta prevalencia, entre ellas las enfermedades cardiovasculares, conocidas o no. La enfermedad arterial periférica (EAP) es una manifestación de la arteriosclerosis en las extremidades inferiores. Un alto porcentaje de los pacientes no presentan sintomatología alguna o su diagnóstico resulta dificultoso. La detección de la EAP mediante el índice tobillo-brazo (ITB) es un método no invasivo y eficiente en la detección de la lesión vascular subclínica. Tiene una alta sensibilidad y especificidad para una estenosis (..) (AU)

The Medical Short Stay Units (UMCE) have an area of preferred on an elderly population and multipathological patients whose most common diagnoses for admission usually are high prevalence diseases. They coincide in a high presence of cardiovascular disease, whether known or not. Peripheral arterial disease (PAD) is one manifestation of arteriosclerosis that is defined by an obstruction of the arterial blood flow in the lower extremities. A high percentage of patients do not exhibit any symptoms and others have a difficult diagnosis. The detection of the PAD through the Ankle–Brachial Index Measurement (ITB) is a non-invasive method, the scope of clinical, highly efficient in the detection of subclinical vascular injury. Objectives This technique offers a high sensitivity and specificity for stenosis (..) (AU)
