Congenital midline nasal masses are uncommon anomalies including nasal dermoids/epidermoids, nasal glial heterotopias and encephaloceles. These lesions can occur at the nasal bridge, extend intranasally and have intracranial extension with communication to the subarachnoid space. Therefore, accurate diagnosis of these lesions is critically important for presurgical planning and prevention of potentially fatal complications. Neuroimaging is essential in the evaluation of congenital midline nasal masses to identify the specific type of lesion, evaluate for the presence of intracranial extension and allow for appropriate presurgical planning.

Paratesticular metastases are rare entities and a paratesticular metastasis of a mucinous appendiceal adenocarcinoma with peritoneal carcinomatosis has not been reported in the literature in the last 15 years. We present a case of mucinous appendiceal adenocarcinoma that progressed to peritoneal carcinomatosis. Twenty months following surgery and intraperitoneal therapy, the patient presented with testicular pain and swelling. Ultrasound examination raised suspicion for a neoplastic process and pathology confirmed a metastatic mucinous adenocarcinoma of appendiceal origin. Radiologists should be cognizant of potential paratesticular metastases in patients with a known history of malignancy with new testicular pain and swelling.

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.

Gastric adenocarcinoma treatment can include endoscopic mucosal resection, surgery, chemotherapy, radiation, and palliative measures depending on staging. Both invasive and noninvasive staging techniques have been used to dictate the best treatment pathway. Here, we review the current imaging modalities used in gastric cancer as well as novel techniques to accurately stage and screen these patients.

The embryonal male sexual differentiation is driven by testosterone, and Anti-Müllerian hormone (AMH). AMH is responsible for regression of Müllerian ducts in a genetically male fetus. Mutations inactivating AMH or its receptors are responsible for persistent Müllerian duct syndrome (PMDS) in virilized 46, XY males. PMDS is a rare genetic disorder affecting males, with less than 300 cases described in literature. The syndrome is usually recognized early in life with patients present with bilateral undescended testicles, and often decreased testosterone production by Leydig cells later in life. The role of testosterone in the development and progression of prostate cancer is well established, and men with low circulating free testosterone are expected to have a lower risk of developing prostate cancer. Indeed, 2 cases of prostate cancer in patients with PMDS have previously been described. Herein, we are reporting the third of prostate cancer in patient with PMDS.
