Item type:Publication, Secondary rectal linitis plastica caused by prostatic adenocarcinoma - magnetic resonance imaging findings and dissemination pathways: A case report(2024); ; ;Rolando Alfonso Cocio ;Jorge Tomás Torres<jats:p>BACKGROUND</jats:p> <jats:p>Secondary rectal linitis plastica (RLP) from prostatic adenocarcinoma is a rare and poorly understood form of metastatic spread, characterized by a desmoplastic response and concentric rectal wall infiltration with mucosal preservation. This complicates endoscopic diagnosis and can mimic gastrointestinal malignancies. This case series underscores the critical role of magnetic resonance imaging (MRI) in identifying the distinct imaging features of RLP and highlights the importance of considering this condition in the differential diagnosis of patients with a history of prostate cancer.</jats:p> <jats:p>CASE SUMMARY</jats:p> <jats:p>Three patients with secondary RLP due to prostatic adenocarcinoma presented with varied clinical features. The first patient, a 76-year-old man with advanced prostate cancer, had rectal pain and incontinence. MRI showed diffuse prostatic invasion and significant rectal wall thickening with a characteristic "target sign" pattern. The second, a 57-year-old asymptomatic man with elevated prostate-specific antigen levels and a history of prostate cancer exhibited rectoprostatic angle involvement and rectal wall thickening on MRI, with positron emission tomography/computed tomography PSMA confirming the prostatic origin of the metastatic spread. The third patient, an 80-year-old post-radical prostatectomy, presented with refractory constipation. MRI revealed a neoplastic mass infiltrating the rectal wall. In all cases, MRI consistently showed stratified thickening, concentric signal changes, restricted diffusion, and contrast enhancement, which were essential for diagnosing secondary RLP. Biopsies confirmed the prostatic origin of the neoplastic involvement in the rectum.</jats:p> <jats:p>CONCLUSION</jats:p> <jats:p>Recognizing MRI findings of secondary RLP is essential for accurate diagnosis and management in prostate cancer patients.</jats:p>1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Complicaciones del uso del BalĂłn Gástrico como Terapia para Control de Peso.(Sociedad de Cirujanos de Chile, 2025-09-01) ;Cristobal Camus ;Nicolás Radic ;Oscar Campos ;Nicolás UrnĂa<jats:p>El balĂłn intragástrico es una opciĂłn no quirĂşrgica para la pĂ©rdida de peso, sin embargo, existen complicaciones que pueden ser leves, como náuseas y dolor epigástrico, o graves, incluyendo perforaciĂłn gástrica, obstrucciĂłn intestinal y pancreatitis. Factores de riesgo, como cirugĂas gástricas previas, uso prolongado del balĂłn e incluso el no utilizar inhibidores de bomba de protones, aumentan la probabilidad de complicaciones serias. El diagnĂłstico temprano es fundamental y la tomografĂa computada es una herramienta muy Ăştil para hacerlo. El pronĂłstico varĂa segĂşn la presencia de infecciones y comorbilidades. La experiencia mĂ©dica y el seguimiento del paciente son clave para minimizar riesgos.Esta revisiĂłn narrativa se fundamenta en la literatura cientĂfica que encontramos sobre las complicaciones del balĂłn gástrico como tratamiento para el control del peso. Para ilustrar las diversas manifestaciones clĂnicas y hallazgos imagenolĂłgicos documentados, se presentan imágenes de casos observados en nuestra instituciĂłn que evidencian dichas complicaciones.</jats:p>6 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Colangiocarcinoma. EvaluaciĂłn por TomografĂa Computada y Resonancia MagnĂ©tica(2019) ;LucĂa Sánchez; <jats:title>Resumen</jats:title><jats:p>El colangiocarcinoma (CC) es el segundo tumor primario maligno más frecuente del hĂgado. La mayor incidencia se registra en Asia y su pronĂłstico es poco alentador. La resecciĂłn quirĂşrgica del tumor es el Ăşnico tratamiento potencialmente curativo. Sin embargo, la mayorĂa de los CC se diagnostican en estadios avanzados de la enfermedad y la recurrencia del tumor es comĂşn. Este trabajo pretende demostrar las caracterĂsticas imagenolĂłgicas de los CC, su clasificaciĂłn, asĂ como tambiĂ©n la evaluaciĂłn preoperatoria por tomografĂa computada (TC) y resonancia magnĂ©tica (RM) que el radiĂłlogo debe realizar actualmente.</jats:p>28Scopus© Citations 2 - Some of the metrics are blocked by yourconsent settings
