ABSTRACT
Abnormalities in renal fusion represent a subset of congenital anomalies of the kidneys and urinary tract (CAKUT). Horseshoe kidneys (HSKs) are the fusion of kidneys at their lower poles. It is the most common form of CAKUT. Symptoms are usually subtle. The diagnosis is usually made incidentally during childhood. Rarely does an HSK become symptomatic later in life. We present the case of an 88-year-old female with a history of HSK who presented to the emergency department (ED) with a three-week history of left-sided flank pain, intermittent nausea, and reduced urine output. Her inpatient workup included imaging that revealed an HSK and bilateral hydronephrosis, which was more prominent on the left. The onset of symptoms for an HSK late in life is extremely rare.
ABSTRACT
The origin of endometriosis has multiple theories, with controversy over which may demonstrate the prominent pathophysiology. The most common extra-pelvic organ system affected by endometriosis is the gastrointestinal tract. Gastrointestinal endometriosis (GE) accounts for 3 to 37% of all endometriosis cases, and appendiceal endometriosis is present in around 3% of GE cases, therefore constituting less than 1% of all endometriosis cases. In this report, we present a 24-year-old female with a past medical history significant for endometriosis status post two excisional laparoscopies who presented with eight months' duration of right lower quadrant pain, constant and stabbing, with rebound tenderness. Appendectomy and histopathology demonstrated focal endometriosis, diffuse serosal fibrovascular adhesions involving the appendiceal serosa/subserosa, as well as a dilated lumen filled with hemorrhagic content. When the appendix is not considered in endometriosis pathology, patients are at increased risk for unresolved pain and further laparoscopic procedures. Prophylactic appendectomy appears to be a worthwhile consideration in patients with chronic pelvic pain, given the high frequency of appendiceal pathology.
