High-flow priapism caused by a pseudoaneurysm and an arteriocavernosal fistula: clinical and radiological approach of 3 cases.

OBJECTIVE: We report three cases of high-flow priapism in three young patients who presented erectile dysfunction after perineal trauma. METHODS: Complete clinical evaluation, blood tests, color Doppler ultrasonography (US), arteriography and selective embolization were performed. RESULTS: The clinical history and physical assessment were compatible with high-flow priapism. Color Doppler US showed a pseudoaneurysm and an arteriocavernosal fistula, which was confirmed and embolized using arteriography. CONCLUSIONS: High-flow priapism has a characteristic clinical presentation and physical examination. The radiologist has an important role in the diagnosis and treatment of this pathology. Color Doppler US and arteriography are essential in the diagnosis and allow embolization of the vascular injury. Prognosis is usually good.

Priapismo arterial por pseudoaneurisma y fístula arteriocavernosa: manejo clínico y radiológico de tres casos / High-flow priapism caused by a pseudoaneurysm and an arteriocavernosal fistula: clinical and radiological approach of 3 cases

OBJETIVO: Describir tres casos de priapismo arterial en pacientes jóvenes que presentaban disfunción eréctil e historia de traumatismo previo. MÉTODOS: Se realizó historia clínica, analítica, ecografía doppler color de cuerpos cavernosos, arteriografía y embolización selectiva lesional. RESULTADOS: La historia y exploración clínicas eran concordantes con un priapismo arterial. En la ecografía doppler color de los tres casos se identificó un pseudoaneurisma y una fístula arteriocavernosa que se confirmó y embolizó mediante arteriografía. CONCLUSIONES: El priapismo de tipo arterial tiene una historia y exploración clínicas características. El papel del radiólogo en el diagnóstico y tratamiento de esta patología es fundamental. La ecografía doppler color y la arteriografía son pruebas diagnósticas de primer orden y permite la embolización selectiva de la lesión vascular de base. El pronóstico generalmente es bueno

Adrenal cavernous hemangioma: is presurgical diagnosis with imaging test possible.

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.

Estudio radiológico de un caso de pseudotumor sarcoideo renal bilateral / Bilateral kidney pseudotumor due to sarcoidosis: a radiological study case

OBJETIVO: Describir un caso de pseudotumor renal bilateral secundario a sarcoidosis en un paciente de 75 años en seguimiento por carcinoma de próstata y con historia de paquimeningitis hipertrófica. MÉTODOS: Se realizó ecografía-doppler abdominal, TC tóraco-abdomino-pélvico y biopsia renal guiada por TC, estudios analíticos, determinación de ECA y tratamiento de prueba con esteroides. RESULTADOS: En las pruebas de imagen se identificaron masa renales bilaterales y adenopatías mediastínicas calcificadas, insuficiencia renal y aumento de la ECA en la analítica y granulomas no caseificantes en la biopsia renal. Tanto la clínica neurológica como la función renal mejoraron con esteroides. CONCLUSIONES: La afectación renal pseudotumoral por sarcoidosis es una patología rara que debe incluirse en el diagnóstico diferencial de las masas renales, principalmente en pacientes con sospecha de enfermedad inflamatoria/autoinmune. Los hallazgos radiológicos del "sarcoide renal" son inespecíficos. Puede obtenerse biopsia guiada por TC/ecografía para diagnóstico histológico a partir de las masas renales(AU)

OBJECTIVE: To report one case of bilateral kidney pseudotumor due to sarcoidosis in a 75 year-old man with prostatic carcinoma and hypertrophic pachymeningitis. METHODS: Renal Doppler, body CT, CT-guided renal biopsy, blood analysis including angiotensin converting enzyme (ACE), blood levels and test-treatment (corticosteroid response) were performed. RESULTS: The radiological studies performed showed bilateral kidney masses and pulmonary calcified hilar adenopathies. Blood analysis showed renal failure and increased ACE levels. Renal biopsy showed non-caseating granulomas. Neurological symptoms and renal failure improved with corticosteroid therapy. CONCLUSION: Bilateral kidney pseudotumor due to sarcoidosis is a rare pathology. Sarcoidosis must be included in the differential diagnosis work up of patients with inflammatory or autoimmune disease and bilateral kidney pseudotumors. Radiological findings of kidney sarcoidosis are quite unspecific. Histological diagnosis with CT guided biopsy or US guided biopsy of kidney masses may be performed(AU)

Estudio clínico-radiológico de tres casos de linfomas testiculares de curso agresivo / Clinical and radiological study of three cases of aggressive course testicular lymphomas

OBJETIVO: Describir las características clínico-radiológicas y las pruebas de imagen en el diagnóstico y extensión/seguimiento del linfoma testicular (LT).MÉTODOS: Se realizó ecografía-doppler color testicular, inguinal, estadiaje con Tomografía Computarizada Multidetector (TCMD); y ecografía-doppler y TCMD en una metástasis cutánea.RESULTADOS: Caso 1: Paciente de 65 años con LT hace 11 años, recidiva en el testículo contralateral 5 años después, metástasis orbitaria a los 8 años y actualmente recidiva con infiltración del nervio cubital. Caso 2: Paciente de 44 años con LT y adenopatías inguinales metastásicas. Caso 3: Paciente de 85 años con LT, adenopatías retroperitoneales y uropatía obstructiva.Histología: LNH difuso B.CONCLUSIONES: El LT suele cursar de forma agresiva, con afectación testicular contralateral, extensión extratesticular o a distancia. Las principales técnicas radiológicas son la ecografía-doppler para el estudio de la enfermedad primaria y el TCMD en la extensión. El diagnóstico es histológico y el tratamiento quirúrgico asociado a radioterapia o quimioterapia, siendo el pronóstico malo(AU)

OBJECTIVE: To describe the clinical and radiological features, and the role of imaging in diagnosis and extension study of testicular lymphoma (TL).METHODS: Testicular and inguinal color Doppler ultrasound, extension-study Multidetector Computed Tomography (MDCT), and Doppler ultrasound and MDCT in an upper extermity metastasis were performed.RESULTS: Case 1: A 65-year-old man with TL 11 years ago, recurrence in the contralateral testis 5 years later, orbital involvement at 8 years and currently recurrence in the arm with ulnar nerve infiltration. Case 2: A 44-year-old man with TL and metastatic inguinal lymphadenopathy. Case 3: An 85 year-old man with TL, retroperitoneal lymph nodes and obstructive uropathy. Histological subtype: B-cell non-Hodgkin´s lymphoma.CONCLUSIONS: TL typically presents as an aggressive disease with contralateral testicular involvement and spreading to regional lymph nodes and non-contiguous extranodal sites. The main radiological techniques are Doppler ultrasound for the study of the primary disease and MDCT in the evaluation of disease extension. Diagnosis is usually obtained after orchiectomy by histological study, and despite the aggressive treatment modalities (surgery associated with radiotherapy or chemotherapy) prognosis remains poor(AU)

Adenocarcinoma de uraco con metástasis cerebrales tardías / Urachal adenocarcinoma with late brain metastases

OBJETIVO: Describir un caso de adenocarcinoma uracal con metástasis cerebrales tardías en un paciente de 61 años que consultó por molestias abdominales y hematuria de 6 meses de evolución.MÉTODO: Con la sospecha clínica de tumoración vesical se realizaron pruebas diagnósticas (citología seriada de orina, cistoscopia, ecografía abdominal y TAC abdominopélvico). Se indicó tratamiento quirúrgico.RESULTADOS: La citología de orina fué negativa. En la cistoscopia se observó una lesión infiltrante en la cúpula vesical. En la ecografía y la TAC se apreció una lesión redondeada de 5 cm, con densidad intermedia, ecos internos ycalcificaciones en la línea media supravesical anterior, que infiltraba la vejiga. El estudio de extensión no mostró hallazgos. Se realizó cistectomía parcial y linfadenectomía. El diagnóstico histopatológico fué adenocarcinoma uracal mucosecretor. Tras 5 años libre de enfermedad el paciente desarrolló metástasis pulmonar y cerebrales.CONCLUSIONES: El adenocarcinoma de uraco es un tumor que debe distinguirse del adenocarcinoma primario vesical. El tipo mucosecretor puede asociar calcificaciones detectables en las pruebas de imagen que deben hacer sospechar el diagnóstico. La presencia de metástasis tardías (tras 5 años libre de enfermedad) y sin signos de recidiva local es un hecho clinicopatológico infrecuente(AU)

OBJECTIVE: To describe a case of urachal adenocarcinoma with late brain metastases in a sixtyone year old man who presented abdominal discomfort and hematuria during six months.METHODS: The clinical suspicion was bladder tumor and diagnostic studies were performed (urinary cytology, cys-toscopy, abdominal ultrasound and abdominopelvic CT scan). Surgical treatment was performed.RESULTS: Negative urinary cytology. Cystoscopy showed a lesion with infiltration of the bladder dome. Ultrasound and CT scan showed a five centimeter rounded lesion, with intermediate density, internal echoes and calcificatio-ns on the anterior supravesical middle line, that infiltrated the bladder. The extension study had not findings. Partial cystectomy and lymphadenectomy were performed. The histopathologic diagnosis was mucin-secreting urachal adenocarcinoma.After five years without disease the patient suffered lung and brain metastases.CONCLUSIONS: Urachal adenocarcinoma is a tumor which must be distinguished of primary bladder adeno-carcinoma. The mucing-secreting adenocarcinoma can be associated with calcifications that can be demostrated on imaging studies. Late metastases without signs of local recurrence (after five years without disease) are an infrequent clinical-pathologic finding(AU)

[Intratesticular varicocele associated with glandular atrophy and parenchymal ultrasound abnormalities]. / Varicocele intratesticular asociado a atrofia glandular y a alteraciones ecográficas parenquimatosas.

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.

[Seminoma and teratocarcinoma: synchronic unitesticular presentation as independent nodules with different histologies? Ultrasound characteristics]. / Seminoma y teratocarcinoma: presentación sincrónica monotesticular como nódulos independientes con distintas histologías? Caracteres ecográficos.

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.

Varicocele intratesticular asociado a atrofia glandular y a alteraciones ecográficas parenquimatosas / Intratesticular varicocele associated with glandular atrophy and parenchymal ultrasound abnormalities

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)

Seminoma y teratocarcinoma: ¿presentación sincrónica monotesticular como nódulos independientes con distintas histologías? Caracteres ecográficos / Seminoma and teratocarcinoma: synchronic unitesticular presentation as independent nodules with different histologies? Ultrasound characteristics

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)

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 same 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 (AU)

[Synchronic bilateral testicular seminomas. Ultrasound diagnosis]. / Seminomas testiculares bilaterales sincrónicos. Diagnóstico ecográfico.

OBJECTIVES: To report a new case of bilateral synchronic testicular tumors, and to perform a bibliographic review on the topic, emphasizing the ultrasound characteristics and oddity of these presentation, which accounts for less than 1% of germ cell testicular tumors. METHODS/RESULTS: 29-year-old patient consulting because of an increase of the testicular size over one year. Physical examination and ultrasound revealed a synchronic neoplastic involvement of the testicles, suggesting the radiological diagnosis of bilateral "seminomatous tumor", with "non seminomatous" foci in one of them. Histologically, tumors were in accordance with ultrasound working diagnosis (seminomas, showing one of them anaplastic foci). CONCLUSIONS: Synchronic testicular involvement by neoplasias is an unfrequent fact, scarcely reported in the literature, being most cases germ cell tumors, mainly seminomas, and shows a good correlation between ultrasound and histologic diagnosis.

[Renal pseudoaneurysm and arteriovenous fistula: color doppler study of a post-lithotripsy simple cyst]. / Pseudoaneurisma y fístula arteriovenosa renal estudio mediante doppler color de quiste simple post-litotricia.

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.

[Synchronous chromophobe renal carcinoma and centrocytic lymphoma]. / Carcinoma renal cromófobo y linfoma centrocítico sincrónicos.

OBJECTIVES: To report a case of synchronic neoplasia--chromophobe renal cell carcinoma and low grade non Hodgkin lymphoma--in a 38-year-old male patient, because, although association of these two neoplasias is known, the fact of renal neoplasia being a chromophobe carcinoma is rarely referred to in medical bibliography (3 cases described after Med-Line search). METHODS/RESULTS: The diagnostic study included ultrasound and CT scan in a patient presenting with in non specific abdominal symptoms and neck adenopathy; patient underwent left radical nephrectomy and excision of neck adenopathy. Histologic and immuno-histochemical studies revealed the coexistence of chromophobe type renal cell carcinoma and diffuse centrocytic lymphoma. CONCLUSIONS: Column in the association between chromophobe histological type renal cell carcinoma and non Hodgkin lymphoma is very rare. Presence of these two tumors in the same patient may pose problems for clinical staging, prognostic predictions, and treatment. Then, due to the fact that it is not usual and that a local stage renal carcinoma presents with neck adenopathies, when they appear possible coexistence of these tumors should be suspected.
