ABSTRACT

La aparición de un nódulo tiroideo se ha convertido en un hecho cotidiano en la práctica clínica diaria. Habitualmente, la adecuada evaluación del nódulo tiroideo requiere la realización de diversas pruebas diagnósticas y múltiples citas médicas, con la consiguiente demora diagnóstica. La instauración de una consulta de alta resolución de nódulo tiroideo evita en gran medida estos inconvenientes, condensando en una única cita todas las pruebas necesarias para la correcta evaluación del nódulo tiroideo. En este trabajo revisamos cuál debe ser la estructura diagnóstica y funcional de una consulta de alta resolución de nódulo tiroideo


Appearance of a thyroid nodule has become a daily occurrence in clinical practice. Adequate thyroid nodule assessment requires several diagnostic tests and multiple medical appointments, which results in a substantial delay in diagnosis. Implementation of a high-resolution thyroid nodule clinic largely avoids these drawbacks by condensing in a single appointment all tests required for adequate evaluation of thyroid nodule. This paper reviews the diagnostic and functional structure of a high-resolution thyroid nodule clinic

ABSTRACT

OBJECTIVE: To describe a case of adrenal cavernous hemangioma in a 67 year old man who presented left lumbar pain. METHODS: Abdominal ultrasound, contrast enhanced ultrasound of the lesion, abdominal-pelvic CT scan, and then left adrenalectomy and pathology were performed RESULTS: Imaging studies showed a large solid-cystic mass with 12 × 11 cm diameters in the left adrenal gland, well defined, with calcifications, which showed peripheral arterial globular contrast enhancement on CT and ultrasound. The lesion displaced neighboring structures without other findings in the abdominopelvic study. The pathology report after adrenalectomy was: cavernous hemangioma with calcifications, ossifications and necrosis. CONCLUSIONS: Cavernous hemangioma is a rare cause of adrenal mass. The globular peripheral contrast uptake and gradual filling of the lesion on dynamic imaging studies (Ultrasound or CT) and phlebolith type calcifications suggest the diagnosis of typical angioma. However, the presence of thrombosis, necrosis and calcifications in large lesions confer an unusual dynamic behavior and force pathology for definitive diagnosis.

ABSTRACT

OBJETIVO: Describir un caso de hemangioma cavernoso suprarrenal en un paciente de 67 años que presentaba dolor lumbar izquierdo. MÉTODOS: Se realizó ecografía abdominal, ecografía de la lesión con ecopotenciador y TC multidetector abdomino-pélvico. Se practicó suprarrenalectomía izquierda y estudio histológico. RESULTADOS: En las pruebas de imagen se apreció en el área suprarrenal izquierda una gran masa sólido-quística de 12 x 11 cm de diámetro, bien delimitada, con calcificaciones groseras, que presentaba realce arterial de contraste y de ecopotenciador de morfología globular en su porción periférica. Dicha lesión desplazaba estructuras vecinas sin infiltrarlas, siendo el resto del estudio abdominopélvico normal. El resultado de la pieza de suprarrenalectomía fue: hemangioma cavernoso con calcificación, osificación y necrosis. CONCLUSIONES: El hemangioma cavernoso es una causa rara de masa suprarrenal. La captación periférica globular de contraste iodado o de ecopotenciador y relleno progresivo de la lesión en el estudio dinámico de imagen (Eco o TC) así como las calcificaciones tipo “flebolitos” sugieren el diagnóstico de angioma típico. Sin embargo la presencia de trombosis-necrosis y calcificaciones en lesiones de gran tamaño le confieren un comportamiento dinámico atípico y obligan al estudio anatomopatológico para establecer un diagnóstico definitivo(AU)

ABSTRACT

OBJECTIVE: To report one case of intratesticular varicocele, infrequent pathology (2% of the cases), with a series of ultrasound peculiarities: testicular atrophy and associated parenchymal abnormalities, in a 24-year-old patient with left testicular pain. METHODS: Ultrasound showed severe left varicocele, mixed type, with the regular extratesticular component and dilated subcapsular and mediastinum vessels, with turbulent flows increasing with Valsalva's manoeuvre, as well as an alteration of the ultrasound pattern of the parenchyma, with hypoechoic and hypovascular areas and diminished testicular size. DISCUSSION/CONCLUSIONS: Intratesticular varicocele is a rare pathology more frequent in the left testicle, which is frequently associated with extratesticular varicocele. The presence of testicular atrophy and associated parenchymal abnormalities has been rarely described in the literature. Clinically they show features overlapping the extratesticular types.

ABSTRACT

OBJECTIVE: To describe the ultrasound characteristics, vascularization pattern (colour Doppler ultrasound) and possible histogenesis of one case of synchronic untesticular seminoma and teratocarcinoma as independent tumor nodules, histologically different, in a 19-year-old patient with testicular mass for eight months. METHODS: Conventional ultrasound, colour Doppler ultrasound, and high resolution Doppler angiogram were performed, analyzing vascular flows. After resection of the tumor, macroscopic and histological sections were related with ultrasound images. RESULTS: The patient showed three independent, well limited, tumoral nodules in the right testicle: two of them heterogeneous, 20 and 33 mm in diameter, with cystic areas and calcifications. The third nodule was solid, hypoechoic and homogeneous, 26 mm in diameter. All nodules presented an increase in vascularization with low resistance arterial flows. Histologically the first two nodules were teratocarcinomas (predominantly mature teratoma and embryonal carcinoma) and the third classic seminoma. CONCLUSIONS: Although seminoma and mixed germ cell tumors are common, "their presentation in the some testicle as independent nodules with different histologies is a rarely referred case in the literature, which allows us to apply a histogenetic and ultrasound-pathologic correlation model in seminomatous and nonseminomatous tumors. The presence of cystic cavities and gross calcifications is highly correlated with teratoma. In our case there are not significant differences in the vascularization pattern with Doppler ultrasound.

ABSTRACT

Objetivo: Describir un nuevo caso de varicocele intratesticular (patología infrecuente -2% de los casos-) con una serie de peculiaridades ecográficas: atrofia testicular y alteraciones parenquimatosas asociadas, en un paciente de 24 años, con dolor testicular izquierdo. Métodos: Se realizó ecografía doppler color, y estudio ecográfico urológico, así como TAC abdominopélvico. Resultados: En el estudio ecográfico se apreció un severo varicocele izquierdo, de tipo mixto, con componente habitual extratesticular y con vasos dilatados subcapsulares y paramediastínicos intratesticulares, con flujos turbulentos que aumentaban con maniobras de Valsalva, así como una alteración de la ecogenicidad parenquimatosa, con áreas hipoecoicas e hipovasculares y disminución del tamaño testicular. Discusión/Conclusiones: El varicocele intratesticular es una patología infrecuente que muestra predilección por el testículo izquierdo, asociándose frecuentemente a varicocele extratesticular. La presencia de atrofia testicular y las alteraciones parenquimatosas asociadas son hechos raramente descritos en la literatura. Clínicamente muestran aspecto solapables con las forma extratesticulares (AU)

ABSTRACT

Objetivo: Describir las características ecográficas, el patrón de vascularización (eco-doppler color) y la posible histogénesis de un caso de presentación sincrónica monotesticular de tumor seminomatoso y teratocarcinoma como nódulos tumorales independientes e histológicamente distintos, en un paciente de 19 años, con una masa testicular de 8 meses de evolución. Métodos: Se realizó estudio convencional ecográfico, eco doppler color y angio-doppler con ecógrafo de alta resolución, analizando los flujos vasculares. Tras la resección del tumor se correlacionaron las secciones macroscópicas e histológicas con los planos ecográficos realizados. Resultados: El paciente mostraba, a nivel testicular derecho, tres nódulos tumorales independientes y bien delimitados: dos de ellos heterogéneos, de 20 y 33 mm de diámetros, con áreas quísticas y calcificaciones. El tercer nódulo era sólido hipoecoico y homogéneo, de 26 mm de diámetro. Todos los nódulos presentaban un aumento de la vascularización con flujos arteriales de baja resistencia. Histológicamente los dos primeros correspondían a teratocarcinomas (teratoma maduro y carcinoma embrionario predominante) y el tercero a un seminoma clásico. Conclusiones: Si bien el seminoma y el tumor mixto de células germinales son habituales, la presentación en un mismo testículo como nódulos independientes, con diferentes histologías es un hecho escasamente referido en la literatura, que nos permite aplicar un modelo histogenético y de correlación ecográfico-patológica en tumores seminomatosos y no seminomatosos. La presencia de cavidades quísticas y calcificaciones groseras se correlaciona altamente con teratoma. En nuestro caso no existen diferencias significativas en el patrón de vascularización con doppler (AU)

ABSTRACT

OBJECTIVES: To describe the clinical and radiological (color doppler ultrasound, CT scan and arteriography) features of a case of renal arteriovenous malformation type mixed fistula with pseudoaneurysm in a female patient after extracorporeal shock wave lithotripsy. METHODS/RESULTS: We report one case of secondary vascular malformation in a 54-year-old female patient who underwent extracorporeal shockwave lithotripsy, presenting as recurrent hematuria. Ultrasound detected a "cystic" formation newly appeared after lithotripsy, being the diagnostic made by a color doppler study which showed a mixed high speed arteriovenous turbulent flow. The lesion showed intense intravenous contrast uptake on CT scan. Diagnosis was confirmed by arteriography. CONCLUSIONS: External shock wave lithotripsy is, as well as interventional procedures, a known cause of renal vascular complications, so that doppler color studies may be diagnostic in patients with suggestive clinical features, focusing specially on those lesions or morphological abnormalities newly appeared when compared to pre-treatment studies.

ABSTRACT

OBJETIVO: Describir las características radiológicas, histopatológicas y citométricas que presenta la afectación perirrenal por macroglobulinemia de Waldenström, ya que esta forma de invasión por linfoma, limitada al espacio perirrenal y no asociada con enfermedad nodal regional, es inusual y difícil de diferenciar de otros procesos (hematomas, liposarcomas, hematopoyesis extramedular...). MÉTODOS/RESULTADOS: Presentamos un caso de afectación perirrenal en un paciente de 68 años, con una enfermedad de Waldenström. La ecografía mostraba masas sólidas hipoecogénicas de localización perirrenal. La realización de una punción guiada por TAC y el posterior estudio histológico y citométrico del tejido extraído confirmaron el diagnóstico. CONCLUSION: Aunque constituye una forma infrecuente de afectación, la detección de masas perirrenales debe hacernos sospechar un linfoma, aún en ausencia de otros signos de enfermedad regional, si bien el diagnóstico debe siempre confirmarse mediante estudio histológico/citométrico (AU)

ABSTRACT

OBJECTIVE: To describe radiological, histological findings and cytometric features of perirenal masses: an unusual involvement pattern of the kidney by Waldenström disease. This pattern, not associated with nodal regional disease should be considered in the differential diagnosis of perirenal pathology (extramedullary hematopoiesis, liposarcoma, haematoma...). METHODS/RESULTS: A 68-year-old man, with Waldenström macroglobulinemia presented in ultrasound exploration bilateral perirenal hypoecogenic mass. Histopathological examination and cytometric determination of fine-needle aspiration biopsy showed a monoclonal lymphoplasmocitoid proliferation of B-cells arranged in a diffuse pattern. CONCLUSION: Although perirenal involvement of the kidney by non Hodgkin lymphoplasmocitoid lymphoma is a rare phenomenon, this disease should be considered in differential diagnosis of perirenal pathology. Histological and cytometric examination are essential for diagnostic evaluation.

ABSTRACT

Se presentan los resultados del tratamiento quirúrgico de la tendinopatía rotuliana en 10 rodillas (9 pacientes, uno de ellos con patología bilateral) de las 22 operadas en nuestro servicio. Todos los pacientes intervenidos se incluían en el estadio 3 de BLAZINA de tendinopatías rotulianas (ver clasificación descrita más adelante). Todos ellos eran deportistas varones que fueron tratados inicialmente con medidas conservadoras en las que se incluían antiinflamatorios no esteroideos, programas de rehabilitación y ortesis durante un tiempo mínimo de seis meses. Se excluyen del estudio, aquellos casos en los que los pacientes habían sido sometidos previamente a otra cirugía sobre la misma rodilla o que presentaban patologías añadidas y los que tenían un tiempo de seguimiento inferior a dos años. La edad media era de 25 años (rango entre 14 y 56 años). La duración media de los síntomas fue de 1,8 años (rango de 6 meses a 4 años) antes de la cirugía. El tratamiento quirúrgico consistió en tenotomías longitudinales, perforaciones en el polo inferior de la rótula y extirpación de calcificaciones. El tiempo de seguimiento postquirúrgico fue de 5'8 años (rango de 24 meses a 14'2 años). Se han valorado resultados clínicos y ecográficos postquirúrgicos. En el 80 por ciento de los casos se obtuvieron resultados clínicos excelentes y en el 20 por ciento restante fueron regulares. El tiempo medio para el reinicio de la actividad deportiva fue de 3'2 meses (rango de 1 a 6 meses). La aparición de un 46 por ciento de anormalidad en las ecografías postquirúrgicas realizadas en siete de los diez tendones operados, no se correlacionó con los resultados clínicos obtenidos. Finalmente, concluyendo este estudio nosotros recomendamos el tratamiento quirúrgico en aquellos pacientes con tendinopatía rotuliana crónica que no han mejorado tras someterse de forma seria y supervisada a las medidas conservadoras de tratamiento durante un mínimo de seis meses (AU)
