Vesicoureteric reflux is the term for abnormal flow of urine from the bladder into the upper urinary tract and is typically a problem encountered in young children.

Urinomas ( Uriniferous fluid collections ) are usually found in  the retroperitoneum, most commonly in  the perirenal space.     As urine extravasates into the retroperitoneum, it can cause lipolysis of the surrounding fat with resultant encapsulation of urine, forming a urinoma.    It can be seen as enhancement of the fluid during the excretory phase of enhancement due to contrast extravasation from the lumen of the genitourinary system.

Lung abscess. A single, contrast-enhanced axial CT scan image of the chest shows a large cavitary lesion in the left lower lobe with a relatively thick wall(black arrows). The cavity has a smooth inner margin and an air-fluid level (white arrow). There is inflammatory reaction in the surrounding lung (yellow arrow). Notice the acute angle the abscess makes with the posterior chest wall.

Rapunzel syndrome is a rare presentation of trichobezoar or gastric ‘hair ball’ where there is a tail like extension of the hair ball into the small bowel through the pylorus causing gastric outlet obstruction.  Human hair (especially the long female hair) is resistant to digestion as well as peristalsis. So they tend to stay in stomach and over a period of time form larger ‘hair ball’.   http://radiopaedia.org/articles/rapunzel-syndrome

Trichobezoars are seen more frequently in pediatric patients and typically occur in young females with emotional problems. The prevalence rate varies from to This patient was operated upon and the stomach was filled by a mass formed fr.

Melanoma is the third most common primary neoplasm that metastasizes to the brain.  MRI  T1: typically hyperintense secondary to hemorrhage or melanin (as above) T2: typically hypointense T1 C+ (Gd): typically enhances in a peripheral rim pattern or a diffusely heterogeneous pattern.  http://radiopaedia.org/articles/intracranial-metastatic-melanoma-2

Insulinomas are the most common endocrine tumours of the pancreas.  These tumours can be relatively small and multiphase contrast enhanced thin slice cross-sectional imaging is ideal.  Most insulinomas are small (2/3rds less than 2cm at presentation) and hyper-vascular. Some contain calcification. Malignant tumours tend to be large.  http://radiopaedia.org/articles/insulinoma

Renal tuberculosis, a subset of genitourinary tuberculosis, accounts for 15-20% of extra-pulmonary tuberculosis and can result in varied and striking radiographic appearances.   Tuberculosis can involve both the renal parenchyma and the collecting system (calyces, renal pelvis, ureter, bladder and urethra) and results in different clinical presentations and radiographic appearances.

This case demonstrates the typical appearances of multiorgan chronic tuberculosis within the abdomen.
