https://www.selleckchem.com/products/acetylcysteine.html Meckel's diverticulum is a remnant of the omphalomesenteric duct, found only in approximately 2% of the population. Although Meckel's diverticulum is often diagnosed in nonsymptomatic patients as incidental radiologic findings, complications of Meckel's diverticulum can also be seen on radiologic evaluation. We present a rare care of perforated Meckel's diverticulum in a geriatric patient demonstrated on contrast computed tomography. This was later confirmed during laparoscopic surgery with pathologic evaluation. © 2020 The Authors.

According to the 2 present cases, and 8 cases previously reported, the distal sides of the sinuses may be connected to internal tissues, such as the subarachnoid, gluteal fissure, peritoneal cavity, or pelvic bone. Since it is difficult to predict the involvement of the distal side of a dermal sinus based on the dermal pit location, ultrasound and magnetic resonance imaging were postulated as a useful modality to aid evaluation. Based on these image findings, complete surgical resection was performed by surgeons. © 2020 The Authors.

A 50-year-old man with RCC measuring 47 mm in diameter. First, we performed transarterial embolization for the tumor, followed by PCA with hydrodissection, which displaced the small intestine from the iceball. The procedure was completed without any complication on the procedural day; however, the patient complained of appetite loss and abdominal pain 2 days after PCA. Computed tomography revealed a bowel injury at the small intestine adjacent to the tumor.
