ABSTRACT

Mycobacterium lentiflavum infrecuentemente provoca patogenicidad en el ser humano, aunque se ha descrito como causante de linfadenitis cervical y afectación pulmonar. Generalmente presenta un curso clínico poco agresivo y se asocia un patrón radiológico nódulo-bronquiectásico. En nuestro caso relatamos un paciente con clínica respiratoria inespecífica y presencia de bronquiectasias y lesiones de morfología pseudonodular en la tomografía computarizada (TC) torácica. En la TC torácica de control y tomografía por emisión de positrones (PET) se evidenció aumento de tamaño y del metabolismo de dichas lesiones. Se realiza biopsia para descartar malignidad creciendo en cultivo de la muestra Mycobacterium lentiflavum


Mycobacterium lentiflavum infrequently causes pathogenicity in humans, although it has been identified as causing cervical lymphadenitis and lung involvement. It usually has a poorly aggressive clinical course and a nodule-bronchiectatic radiological pattern is associated. In our case, we report a patient with a nonspecific respiratory clinic and presence of bronchiectasis and pseudonodular morphology lesions in thoracic computed tomography. In the thoracic CT scan of positron emission tomography (PET) there was evidence of an increase in the size and metabolism of these lesions. Biopsy is performed to rule out malignancy, with Mycobacterium lentiflavum growing in sample culture

ABSTRACT

We present the case of a 74 year old female patient, with clinical criteria of liver cirrhosis caused by hepatic C virus who required several admissions in our hospital over a five month period. She was given several blood transfusions because of repeated clinical manifestation of gastrointestinal bleeding without a clear origin. Her last admission was due to intermittent melenas, secondary anemia and hemodynamic angina. The patient's study included clinical analysis, fibrogastroscopy, colonoscopy, opaque enema, spiral CT and supraortic vessels arteriography. Because all the results to diagnose and locate the patient's disease were negative, she was referred to our service for a scintigraphy study. As it was an emergency case because of the patient's serious hemodynamic condition, a 99mTc-sulphur colloid scintigraphy was chosen, the results of which showed and located active gastrointestinal bleeding requiring urgent surgical intervention. The laparotomy with intrasurgical enterotomy and fibrogastroscopy undertaken ratified gastrointestinal bleeding, and the result of the biopsy of the jejunum removed in the intervention confirmed bowel angiodysplasia. Given the low incidence of gastrointestinal bleeding secondary to bowel angiodysplasia and absence of bibliographic references regarding the diagnosis of this disease in the above mentioned site by means of 99mTc-sulphur colloid scintigraphy in particular, we consider it interesting to highlight this case, in which the capability of this nuclear medicine technique for quick and non-invasive detection and location of gastrointestinal bleeding has been highly proven.

ABSTRACT

Presentamos el caso de una paciente mujer de 74 años de edad, con criterios clínicos de cirrosis hepática por virus hepatitis C, que requirió varios ingresos hospitalarios en nuestro centro durante un período de cinco meses siendo politransfundida por presentar repetidos cuadros de sangrado intestinal de localización incierta. El último ingreso fue motivado por melenas intermitentes, anemia y angor hemodinámico secundario. El estudio de la paciente incluyó la práctica de analíticas, fibrogastroscopias, colonoscopias, enema opaco, angioTAC y arteriografía de troncos aórticos. Todas estas exploraciones fueron negativas para el diagnóstico y localización de la patología que presentaba la paciente, lo que motivó la solicitud a nuestro servicio de un estudio gammagráfico. Debido a la urgencia del cuadro por el severo estado hemodinámico de la paciente, se optó por la realización de una gammagrafía con sulfuro coloidal marcado con 99mTc donde se objetivó y se localizó la existencia de un sangrado intestinal activo efectuándose posteriormente una intervención quirúrgica de urgencia.La laparotomía con enterotomía y fibrogastroscopia intraoperatoria realizadas ratificaron la existencia de sangrado intestinal y el resultado de la biopsia de las asas yeyunales resecadas en la intervención fue compatible con el diagnóstico de angiodisplasia intestinal. Dada la baja incidencia de sangrado digestivo secundario a angiodisplasia de intestino delgado y la ausencia de referencias bibliográficas relativas al diagnóstico de esta patología en dicha localización mediante la gammagrafía con sulfuro coloidal-99mTc en particular, consideramos interesante destacar este caso donde se demuestra la capacidad de este tipo de prueba en la detección y localización no invasiva y rápida del sangrado intestinal (AU)

ABSTRACT

We introduce you a case report of a female patient who has got a chronic liver disease and who entered our hospital with clinical suspicion of pulmonary embolism. The radionuclide lung perfusion scan using 99m Technetium-labelled with macroaggregated albumin, showed an abnormal uptake out of the lungs in liver, spleen, and kidneys. Once all possible etiologies of extrapulmonary uptake were excluded and confirming that the hepatopulmonary syndrome clinical criteria were coincident with our case, we attribute that the abnormal extrapulmonary uptake was explainable due to this syndrome. This is an hepatopulmonary syndrome case in which nuclear medicine techniques were decisive for the diagnosis in front of other diagnostic tests (radiography, echography and CT) that gave valuable but non conclusive information.
