RESUMEN
While germ cell testicular cancer is rare and only accounts for 1% of cancers in males, it is the most common solid malignancy among men between 14 and 44 years of age. Testicular cancer can be surgically excised by orchiectomy and is highly responsive to both chemotherapy and radiation therapy. Therefore, testicular tumors generally have the best cancer prognoses, especially since the majority are localized in the initial stage. However, long-term outcome depends on the potential for germ cell testicular cancer to metastasize, both proximal to the testicles and distally throughout the body. Germ cell testicular cancer metastasis to soft tissue, including the trunk, and extremities, appears to be exceedingly rare, as reflected in the extremely limited number of published cases (total of seven patients reported in literature). Vague symptomatology, delayed medical attention, and inconsistent treatment compliance may contribute to testicular soft tissue metastasis and underreporting of these tumors. Here, we report a case of metastatic non-seminomatous germ cell testicular cancer with a large necrotizing, ulcerative mass in the left Iliopsoas muscle and posterior abdominal wall.
RESUMEN
Acute appendicitis is a surgical emergency. However, the presence of vermiform appendix in a hernial sac is rare. It is even rarer to find inflamed appendix in an hernial sac. The most common site is right groin hernia (Inguinal > Femoral). There is low incidence of an incisional hernia following renal transplantation, as compared to patients with laparotomy. Appendicitis in hernial sac masquerades clinical presentation of an incarcerated hernia. Computed tomography plays a pivotal role in early diagnosis, demonstrating a dilated appendix with wall thickening and peri-appendiceal fat stranding. Patients are managed with appendectomy. The management of appendiceal hernias without inflammation remains controversial, with few reported cases managed with hernia sac repair or appendectomy. In this report were described a case of appendicitis in an incisional hernia following renal transplantation which was managed with appendectomy.
RESUMEN
While ingestion of a foreign body by children is common, diagnosis is often challenging, especially when the consumption by a young child is unwitnessed and presenting symptoms mimic other medical conditions. If the foreign body does not pass spontaneously, radiological imaging studies are typically performed, but visualization and identification of the ingested foreign object can be inconclusive, especially when an unidentified mass is radio translucent. Under this circumstance, physicians often have to go on a "fishing expedition", using exploratory endoscopy and/or surgery to identify and extract the object that became lodged. In this report we discuss a case of a 3 year-old boy who presented with abdominal pain and signs of bowel obstruction. Imaging revealed an ingested "radiolucent" foreign body, masqueraded as soft-tissue mass and enteric duplication cyst, delaying the diagnosis. Systematic shape and density reanalysis of CT and US imaging suggested a hollow object lodged at the terminal ileum. The patient underwent exploratory laparotomy with extraction of a hollow toy "fish". There is a dearth of literature regarding hollow ingested objects. This case report highlights the importance of systematic density and shape imaging analyses in order to identify and locate hollow ingested objects.
RESUMEN
BACKGROUND: Current literature supports the use of the three-view plain-radiograph series supplemented, when necessary, with helical computed tomography to evaluate the cervical spine in patients who have sustained trauma injury. The purpose of this study was to determine if helical computed tomography alone can be used to evaluate the cervical spine for acute osseous injury following high-energy trauma, thus eliminating the need to make radiographs. METHODS: Patients were prospectively evaluated with helical computed tomography scanning of the cervical spine and standard three-view plain radiography. At a later date, the plain radiographs and computed tomography scans were independently reviewed by two radiologists who were blinded to both the initial interpretation and the interpretation of the corresponding study. The radiologists documented whether the plain radiographs were adequate and whether they showed an acute process. The findings in the study were compared with the initial findings and, when necessary, with the discharge summaries to determine if an injury had been identified. The accuracy of the plain radiographs, of the plain radiographs that had been deemed adequate, and of helical computed tomography used alone was ascertained. RESULTS: Plain radiographs and helical computed tomography scans were made for 407 patients, and traumatic injuries were identified in fifty-eight of them. Plain radiographs alone were adequate for 194 (48%) of the 407 patients. Plain radiographs had a sensitivity of 45%, a specificity of 97%, a positive predictive value of 74%, and a negative predictive value of 91%. Adequate plain radiographs had a sensitivity of 52%, a specificity of 98%, a positive predictive value of 81%, and a negative predictive value of 93%. Helical computed tomography had a sensitivity and specificity of 98%, a positive predictive value of 89%, and a negative predictive value of >99%. The sensitivity, positive predictive value, and negative predictive value of adequate plain radiographs differed significantly from those of helical computed tomography alone (p < 0.001). Twelve (48%) of twenty-five adequate plain radiographs of patients in whom an injury had been identified on computed tomography missed that injury. Helical computed tomography alone missed one (2%) of the fifty-eight injuries. CONCLUSIONS: Although helical computed tomography has a limited ability to detect pure ligamentous injury, it can be safely used without plain radiographs to evaluate the cervical spine for osseous abnormalities such as fractures and dislocations after high-energy trauma.
