Publication El signo del remolino en la torsiĆ³n omental: a propĆ³sito de un caso(2023) Barahona Zuleta, Daniela; Covarrubias, Juan; Ahumada; ĆscarLa torsiĆ³n del omento mayor es una causa infrecuente de dolor abdominal agudo en el servicio de urgencias, ya sea de origen primario o secundario. Corresponde a la rotaciĆ³n del omento en su eje largo que determina congestiĆ³n venosa e isquemia. ClĆnicamente imita apendicitis o colecistitis aguda, siendo el diagnĆ³stico realizado frecuentemente en forma quirĆŗrgica. Existen hallazgos caracterĆsticos en tomografĆa computarizada, como el Ā«signo del remoOmental torsion is a rare cause of acute abdominal pain in the Emergency Department, being of primary or secondary origin. It involves rotation around its long axis, resulting in venous congestion and ischemia Clinically it mimics acute appendicitis or cholecystitis, and frequently the diagnosis is made surgically. There are characteristic findings on computed tomography, like the whirl sign , that aid the preoperative diagnosis if the radiologist knows the disease. The treatment could be conservative; however, some authors prefer surgical management to avoid later complications.linoĀ», que permiten el diagnĆ³stico prequirĆŗrgico si el radiĆ³logo conoce la patologĆa.

Tiene una amplia variabilidad de presentaciones clĆnicas, que van desde disnea y cianosis en lactantes hasta adultos asintomĆ”ticos. La lobectomĆa mediante toracoscopia asistida por vĆdeo es el tratamiento de elecciĆ³n, incluso en pacientes asintomĆ”ticos, para evitar la infecciĆ³n. La tomografĆa computarizada contrastada es el examen de elecciĆ³n para determinar la anatomĆa y evaluar el acceso quirĆŗrgico. Pulmonary sequestration is a rare congenital malformation of dysplastic lung tissue, which is separated from the rest of the lung, without communication with the bronchial tree. It has a wide variability of clinical presentations, ranging from dyspnea and cyanosis in infants to asymptomatic adults. Video-assisted thoracoscopy lobectomy is the treatment of choice, even in asymptomatic patients, to prevent infection. Contrast computed tomography is the examination of choice to determine the anatomy and evaluate the surgical access.Publication Sciatic and median nerve neurolymphomatosis as initial presentation of B-cell lymphoma(2022) Barahona Zuleta, Daniela; Adlerstein, Isabel; Donoso, J.; Mercado, F.Neurolymphomatosis (NL) is the infiltration of cranial nerves or nerves and roots from the peripheral nervous system by lymphoma, usually by B-cell non-Hodgkin's lymphoma. It is uncommon as initial presentation of the disease and can lead to extremely heterogeneous clinical manifestations. We report the case of a 72-year old male who presented with numbness of the right hand, progressive weakness in both lower limbs and weight loss. 18F-FDG PET/CT showed bilateral hypermetabolic adrenal masses, gastric ulcer, small hypermetabolic adenopathies, multiple focal bone marrow uptake and intense uptake in both sciatic nerves and right median nerve. A node and gastric biopsy confirmed diffuse large-B-cell lymphoma, activated B cell type, with posterior resolution of peripheral nerves uptake after beginning chemotherapy.Publication PĆ”ncreas heterotĆ³pico en intestino delgado: serie de casos con correlaciĆ³n anatomopatolĆ³gica(2022) Barahona Zuleta, Daniela; Schiappacasse, Giancarlo; FAURE RODRIGUEZ, MARIA IGNACIA; GonzĆ”lez Valenzuela, Pablo; Benoit, Elisa; gallardo santis, alejandra; CAVALLA CASTILLO, CRISTIANEl pĆ”ncreas heterotĆ³pico corresponde a tejido pancreĆ”tico fuera de su localizaciĆ³n habitual. Dentro de sus localizaciones mĆ”s frecuentes, se encuentran el duodeno, el estĆ³mago y el yeyuno proximal. En la mayorĆa de los casos es un hallazgo imagenolĆ³gico incidental, cuyo diagnĆ³stico definitivo se obtiene a travĆ©s de un estudio histolĆ³gico, ya que sus caracterĆsticas no son patognomĆ³nicas. En este trabajo describimos una serie de cuatro casos de pĆ”ncreas heterotĆ³picos como nĆ³dulos yeyunales incidentales, visualizados mediante tomografĆa computada y tomografĆa por emisiĆ³n de positrones, todos con confirmaciĆ³n histolĆ³gica posquirĆŗrgicaPublication Lobular breast cancer bone metastases detected with 68Ga-DOTATATE PET/CT performed for intestinal neuroendocrine tumor(2022) Barahona Zuleta, Daniela; Chong Medel, Guillermo; Sola, Jose
