[Hematuria as the first sign of pelvic chondrosarcoma]. / Hematuria como primer signo del condrosarcoma de pelvis.

Chondrosarcoma is a malignant tumor which often affects the pelvic ring and its symptomathology is non-specific and insidious. We display a case of a right iliopubic branch chondrosarcoma in a 62-year-old male whose first sing was a four-year history of sporadic macroscopic haematuria, related to efforts. After being studied by the Urology Department by cystoscopy and biopsy of bladder tumor, chondral cells were appreciated. Further study with imaging tests diagnosed low-grade chondrosarcoma with bladder infringement. The case is assessed by Musculoskeletal Tumors Committee and a multidisciplinary approach is carried out through en bloc resection and pelvic floor reconstruction. Currently the patient remains asymptomatic.

El condrosarcoma es un tumor maligno que afecta con frecuencia la pelvis y su sintomatología es inespecífica e insidiosa. Describimos el caso de un condrosarcoma de la rama iliopubiana derecha en un varón de 62 años cuyo primer signo de aparición fue una hematuria macroscópica esporádica, relacionada con esfuerzos y de cuatro meses de evolución. Tras ser estudiado por el servicio de urología mediante cistoscopía con biopsia de tumoración en pared vesical se aprecian células de estirpe condral. Tras posterior estudio con pruebas de imagen se diagnostica condrosarcoma de bajo grado con invasión de la vejiga, por lo que es valorado en el comité de tumores musculoesqueléticos y se realiza un abordaje multidisciplinar mediante exéresis en bloque y reconstrucción del suelo pélvico. Actualmente el paciente continúa asintomático.

Subcutaneous lymphoid follicular hyperplasia secondary to vaccination: correlation of ultrasound findings with clinical and histological findings. / Hiperplasia folicular linfoide subcutánea secundaria a vacunas: descripción de los hallazgos ecográficos y correlación clínico-patológica.

In recent years, the use of vaccines has been standardized within vaccination programs. Adverse effects at the puncture site are usually mild and transient. Nevertheless, in some cases, persistence subcutaneous nodules can develop; these are often underdiagnosed because they are so rare and because of the long time that can transpire between the vaccination and their appearance. Histologically, they consist of a lymphoid follicular hyperplasia that occurs as a reaction to the aluminum particles usually used as an adjuvant in some vaccines. We were unable to find any reference in the radiological literature to these soft-tissue nodules secondary to vaccination. We report the characteristic ultrasound findings that will enable radiologists to identify or strongly suspect these lesions and thereby avoid unnecessary imaging tests that might lead to confusion and inadequate management of these patients.

Varices en el ligamento redondo / Varices in the round ligament

Las varices del ligamento redondo son una entidad muy poco frecuente que sólo se ha descrito en mujeres embarazadas como una masa inguinal, normalmente en el tercer trimestre de gestación.La ecografía en modo B y Doppler color constituyen una herramienta diagnóstica fundamental, ya que permiten realizar un diagnóstico radiológico de certeza, excluyendo otras posibilidades clínicas de masa inguinal.Dado que el tratamiento es conservador, es imprescindible que el radiólogo conozca esta entidad y sus características ecográficas, lo que permitirá la realización de un diagnóstico correcto que evitará una exploración quirúrgica innecesaria (AU)

Varices in the round ligament are very rare and have only been reported in pregnant women as an inguinal mass normally detected in the third trimester of gestation.AbstractB-mode and Doppler color ultrasonography are fundamental tools in the diagnosis, because they make it possible to reach a conclusive diagnosis and to rule out other clinically possible inguinal masses.AbstractGiven that the treatment is conservative, it is essential for the radiologist to be familiar with this condition and its ultrasonographic characteristics to enable the correct diagnosis and avoid unnecessary surgical exploration (AU)

[Tumors of the oral cavity: the usefulness of dynamic CT]. / Neoplasias de la cavidad oral. Aportaciones del estudio de tomografía axial computarizada dinámica.

OBJECTIVE: To demonstrate the usefulness and importance of including "puffed-cheek" dynamic CT (PCCT) in the protocol for the diagnosis and staging of tumors of the oral cavity. MATERIAL AND METHODS: This is a prospective study of 62 (38 male and 24 female) patients with epidermoid carcinoma of the oral cavity diagnosed and treated at our hospital during an 18-month period. The site of the primary tumor was the tongue (n=19), floor of the mouth (n=3), lip (n=3), gums (n=6), retromolar trigone (n=7), buccal mucosa (n=8), and a combination of the last three locations (n=16). In addition to conventional CT examination, all patients underwent dynamic CT of the oral cavity while maintaining their cheeks puffed out. RESULTS: PCCT provided additional information in 39 patients (63%), giving a better view of the tumor, its extension, or both. PCCT detected eight lesions (17%) that were not visible on the conventional CT study; these lesions were located in the tongue (n=3), retromolar trigone (n=1), buccal mucosa (n=3), and upper gum (n=1). PCCT was especially useful for evaluating lesions with superficial extension, in particular those in the buccal mucosa, retromolar trigone, and gums. PCCT provided no additional information about the tumors on the floor of the mouth. CONCLUSIONS: The habitual contact between the mucosal surfaces of the oral cavity makes some clinically obvious lesions difficult to identify at CT. The interposition of air acts as a natural contrast, separating the gums from the mucosa of the buccomaseteric region; PCCT provides relevant information and should be included in the imaging workup in patients with tumors of the oral cavity.

Neoplasias de la cavidad oral. Aportaciones del estudio de tomografía axial computarizada dinámica / Tumors of the oral cavity: the usefulness of dynamic CT

Objetivos. Demostrar las aportaciones y la importancia en el diagnóstico y la estadificación de las neoplasias de cavidad oral de una tomografía computarizada dinámica hinchando los carrillos (TCHC) incluida en el protocolo de estudio. Material y métodos. Estudio prospectivo de 62 pacientes con carcinoma epidermoide de cavidad oral, diagnosticados y tratados en nuestro hospital en un periodo de 18 meses. Las localizaciones de la lesión tumoral primaria fueron: lengua (n = 19), suelo de la boca (n = 3), labio (n = 3), encía (n = 6), trígono retromolar (n = 7), mucosa bucal (n = 8) y una combinación de las tres últimas localizaciones (n = 16). En estos pacientes al estudio de TC convencional se añadió una TC dinámica restringida a la cavidad oral, en la que el paciente mantenía hinchados los carrillos. Resultados. Con la TCHC se obtuvo información adicional en 39 pacientes (63%), mejorando la visualización del tumor y/o su extensión. Se detectaron 8 lesiones (17%) no visibles en el estudio estándar (lengua [n = 3], trígono retro-molar [n = 1], mucosa bucal [n = 3] y encía superior [n = 1]). La maniobra fue de especial utilidad para evaluar lesiones con extensión superficial, especialmente en los tumores de la mucosa bucal, el trígono retromolar y la encía. No obtuvimos información adicional en las neoplasias del suelo de la boca. Conclusiones. El contacto habitual entre las superficies mucosas de la cavidad oral dificulta la identificación de algunas lesiones. La interposición de aire como contraste natural, separando la mucosa de la encía de la región bucomasetérica, aporta información relevante, por lo que hemos incluido la TCHC como exploración rutinaria adicional en el protocolo de estudio de los pacientes con neoplasia de la cavidad oral
