“…Therefore, abdominal CT and U/S, barium enema, and colonoscopy are essential investigations for the recognition of invagination [ 1 – 4 , 10 – 13 ]. U/S has a 60% diagnostic accuracy for bowel obstruction, and it increases significantly in the presence of a palpable mass [ 2 , 21 , 22 ]. A barium enema was used as a diagnostic tool in several studies, with a diagnostic accuracy of 25% to 45% [ 3 ].…”

Patient: Female, 65-year-old Final Diagnosis: Intussusception Symptoms: Diarrhea • fatigue Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual clinical course Background: Intussusception is a rare pathological entity in adults and remains a diagnostic challenge for clinicians, as it shares many clinical signs and symptoms with other morbid conditions (including appendicitis, abdominal hernias, colic, volvulus, and Meckel diverticulum). High clinical suspicion and use of appropriate imaging techniques are essential for early diagnosis and treatment of intussusception. Surgical intervention is the treatment of choice in cases of sustained and persistent invagination. Case Report: We present the case of a 65-year-old woman with a medical history of Crohn’s disease, diabetes mellitus type II, hypertension, and rheumatoid arthritis. She was hospitalized for diarrhea, fatigue, and anemia. Computerized tomography of the abdomen and a colonoscopy revealed telescoping of the ileum, ileocecal valve, and part of the ascending colon inside the terminal segment of the ascending colon. The antegrade ileocolic intussusception was treated by performing a right hemicolectomy. The pathologic examination of the excised intestine showed mucosal lesions compatible with Crohn’s disease, an inflammatory fibroid polyp at the terminal section of the ileum, and a low-grade appendiceal mucinous neoplasm. Conclusions: Regardless of the etiology, when the normal motility of the intestine is altered, it can lead to invagination. Although intussusception is rare, it must always be part of the differential diagnosis for a patient presenting with constant abdominal pain.

“…Pseudokidney sign (PKS) is a characteristic sonographic finding of an abnormal mass resembling a normal kidney (Figure 1) with a reniform appearance and a hyperechoic center surrounded by a hypoechoic area [3,4]. The sign was first reported in colorectal carcinoma [4], and since then it has been documented in many other bowel disorders such as intussusception, necrotizing enterocolitis, midgut volvulus, sigmoid volvulus, diverticulitis, regional enteritis, small bowel lymphoma, and small bowel ischemia [3][4][5][6]. However, the sign is not pathognomonic for bowel pathology because it has been seldom reported in gastric cancer [4,6].…”

Pseudokidney sign (PKS) is a characteristic sonographic finding of an abnormal mass with a reniform appearance, and a hyperechoic central region surrounded by a hypoechoic area. It has been seldom documented in gastric cancer. A 75-year-old male patient presented with a palpable abdominal resistance in the left upper abdominal quadrant and ultrasound evaluation revealed a well-vascularized mass presenting with PKS. Regional lymphadenopathy was also found, and the working diagnosis of gastric cancer was established. The suspected diagnosis was later verified endoscopically and on pathohistological examinations as gastric adenocarcinoma. Computed tomography staging also revealed distant metastases to the lungs, liver, and adrenal glands and abdominal lymphadenopathy. The PKS often indicates gastrointestinal pathology, and it may be seen in benign and malignant conditions due to gastrointestinal wall thickening. Therefore, additional diagnostic examinations are advised for a more definite diagnosis.
