They comprise approximately 80% of mucinous ovarian tumors and 20-25% of all benign ovarian tumors.. Renal cell carcinomas (RCC) (historically also known as hypernephroma or Grawitz tumor) are primary malignant adenocarcinomas derived from the renal tubular epithelium and are the most common malignant renal tumor.They usually occur in 50-70-year old patients and macroscopic hematuria occurs in 60% of the cases. elongated paraovarian cyst; cystic ovarian neoplasm(s): identification of a separate ovary helps distinguish a hydrosalpinx from a cystic ovarian mass, an important distinction because malignancy is rare with an extraovarian The right lung appears slightly smaller than the left lung on this frontal radiograph. The normal appendix testis is 1 to 4 mm in length, and it is oval or pedunculated Torsion of the appendix testis (occasionally called torsion of the hydatid of Morgagni) is the most common cause of an acute painful hemiscrotum in a child. Patients may present with sudden-onset pelvic pain, pelvic mass, or they may be asymptomatic and the hemorrhagic ovarian cyst is an incidental finding 4..

Neurogenic bladder is a term applied to a dysfunctional urinary bladder that results from any lack of coordination between the central nervous system and the somatic nervous system, 5 including injuries to the central or peripheral nerves that control and regulate urination. Aberrant renal arteries may be present, and may complicate surgical procedures. Accessory renal arteries are a common variant of the renal arteries.They are present in ~25% (range 20-30%) of the population and bilateral in ~10% 1.Accurate identification is of utmost importance for surgical planning prior to live donor transplantation 2,3 and renal artery embolization for various reasons 4,5.. Most hydroceles are acquired and present with progressing painless scrotal mass.During the physical examination, hydrocele characteristically transilluminates when evaluated with a light source. It is seen as a wide spectrum of altered morphology in the female breast from innocuous to those associated with risk of carcinoma.
