Pseudocyst in ectopic pancreas: diagnosis and percutaneous treatment guided by MDCT

Duodenal Heterotopic Pancreas with a Large Retention Cyst: A Case Report and Literature Review

“…However, the present case was asymptomatic, although the cystic diameter increased from 3 to 6 cm from the time of the initial examination to the time of surgery 1 year later, which may have made the preoperative diagnosis more difficult. A preoperative diagnosis was possible in one case of jejunum HP (23) and five cases of gastric HP. Pancreatic juice and acinar cells were collected and diagnosed by EUS-guided fine-needle aspiration (20,24), and cyst excision was performed by endoscopic submucosal dissection (17).…”

“…A definitive diagnosis of HP with retention cyst should be accurately rendered considering the following characteristic criteria: HP presents with a CT density similar to that of the normal pancreas (22); HP is physiologically located in the gastric antrum, which is a favorable site for HP development (8,22); the retention cyst wall shows thickness (29); and the cyst category can be confirmed by performing a safe puncture and analyzing the pancreatic enzymes from the fluid content (20,23,24). However, a preoperative diagnosis is usually difficult because the HP parenchyma must present with a relevant volume to enable the HP diagnosis by imaging.…”

Tomographic findings in Meckel’s diverticulitis

“…Because it is difficult to diagnose, MD continues to be a major challenge in medical practice (4) . Various conditions can mimic MD and its complications, such conditions including appendicitis, diverticula in other intestinal segments, ureterolithiasis, intussusception, duplication cysts, angiodysplasia, and hemorrhagic tumors (5)(6)(7)(8)(9) . Taken together with the clinical manifestations, the results of some imaging examinations, such as ultrasound and CT, aid in making the correct diagnosis.…”
