Dos formas de presentación del seudotumor inflamatorio pulmonar / Two Types of Presentation of Pulmonary Inflammatory Pseudotumors

El seudotumor inflamatorio es una patología relativamente poco frecuente de etiología incierta, generalmente considerada de origen reactivo. Puede observarse en diferentes localizaciones como masas únicas o múltiples. La intrapulmonar es una de sus posibles formas de presentación. A pesar de su baja frecuencia, esta patología debe tenerse en cuenta a la hora de realizar el diagnóstico diferencial de nódulos pulmonares. De otro modo, los resultados histológicos y de las pruebas de imagen pueden llegar a ser confusos. Además, presenta una baja malignidad con buena respuesta al tratamiento quirúrgico y en menor medida al farmacológico. Presentamos una revisión bibliográfica de esta patología basándonos en dos casos observados en nuestro hospital. Ambos pacientes comenzaron con cuadros respiratorios inespecíficos y nódulos pulmonares en pruebas de imagen, sospechosos de proceso neoplásico. Tras su estudio exhaustivo se llegó al diagnóstico de seudotumor inflamatorio pulmonar con excelente respuesta al tratamiento usado en cada caso(AU)

Inflammatory pseudotumors are a relatively uncommon pathology of uncertain etiology, generally considered to be reactive in origin. They may be observed in different locations as single or multiple masses. One of the possible forms of presentation is intrapulmonary. Despite its low frequency, this pathology should be considered in the differential diagnosis of lung nodules, even though the histologic results and the imaging tests can become confusing. In addition, pulmonary inflammatory pseudotumors present a low malignancy with good response to surgical treatment as well as to pharmacological therapy, although to a lesser degree. We present a bibliographic review of this pathology based on two cases observed in our hospital. Both patients debuted with non-specific respiratory symptoms and lung nodules on imaging studies that were suspicious for neoplastic processes. After an exhaustive study, the diagnosis of pulmonary inflammatory pseudotumor was reached, with excellent responses to the treatment used in each case(AU)

Computer vision techniques for breast tumor ultrasound analysis.

In this paper, we present a new approach to the segmentation and analysis of solid breast nodules in ultrasonography. We have applied computer vision techniques to segment the nodules and analyze a series of diagnostic criteria which can help discriminate malignant and benignant tumors. The segmentation is carried out in a semiautomatic way, whereas the analysis of the diagnostic criteria involves several computational methods. The techniques which we propose have provided quite satisfactory results and show the usefulness of image processing in the diagnosis through medical imaging.
