The "serpent sign"-A classical sign in a nonclassical location: A case report of breast hydatid cyst.

Hydatid cyst is a rare breast pathology; however, it should be included in the differential diagnosis of any breast mass. The history and imaging findings can sometimes raise suspicion of the hydatid nature of the mass. The presence of certain imaging signs specific to hydatid cysts can further indicate this diagnosis. Nevertheless, the definitive diagnosis remains histological, and the treatment is principally surgical. Herein, we present a case of a 38-year-old female who was found to have the "serpent sign" on ultrasonography, which is pathognomonic for ruptured hydatid cysts, as part of the imaging workup for a left breast lump. This case report underscores the importance of characteristic imaging features such as the "serpent sign" in the diagnosis of hydatid disease, especially in unusual sites like the breast where the index of suspicion is particularly low. Recognition of such signs elicits special pre- and intraoperative precautions to minimize complications like local dissemination and anaphylactic shock.

Unilateral renal agenesis, blind-ended ureter and ectopic ureterocele: An incidental finding on abdominal CT scan.

Congenital renal anomalies are among the most common birth defects. They are often detected antenatally. If not, they can manifest in adulthood with variable clinical presentations. Herein, we present a case of a 72-year-old male patient who was incidentally found to have an extremely rare combination of urinary tract defects comprising: right-sided unilateral renal agenesis, blind ureter, and ectopic ureterocele.

Duplex Collecting System With Ectopic Ureter Into the Posterior Urethra: A Case Report.

The ureters are muscular tubes that carry urine from the kidneys to the urinary bladder and are typically implanted in the superolateral angle of the trigone of the urinary bladder. Although renal anomalies are common, especially in the kidneys, ectopia of the ureter is rare. Clinical presentation depends on the insertion of the ectopic ureter, varying from asymptomatic (mostly in males) to recurrent urinary tract infections (UTIs) and incontinence (mostly in females). Radiology is the best diagnostic tool to achieve a diagnosis. Ultrasound (US), intravenous renogram (IVR), micturition cystourethrogram (MCUG), and others are used to diagnose ectopic ureters, with US and MCUG being the gold standard modalities. Treatment depends on the functionality of the part drained by the ectopic ureter. Heminephroureterectomy and ureteroureterostomy are among surgical treatments for ectopic ureter, and it is either open or laparoscopic surgery. Herein, we present a case of a four-year-old female patient who presented with recurrent UTIs and incontinence.
