“…[1][2][3][4][5] The pathology can also be incidentally detected on various nuclear medicine scans performed for different reasons. [6][7][8][9][10][11][12] It is recognized that Meckel diverticulum scintigraphy can incidentally detect a variety of malignant [13][14][15][16] or benign [17][18][19][20][21][22] processes, including pelvic crossed fused renal ectopia. 23 Our case shows that horseshoe kidney can be added to this list.…”

An 8-year-old male patient with history of bloody stools underwent a Meckel diverticulum scintigraphy to evaluate for ectopic gastric mucosa. The static images showed 2 abnormal foci of radiotracer accumulation in the mid-abdomen. Contrary to the renal activity, the foci appeared more prominent on the anterior view and localized anteriorly to the expected kidneys location on the left lateral view. Carefully reviewed dynamic acquisition revealed faint catenary-shaped activity in this region on earlier images, gradually evolving into 2 prominent foci on later images. A horseshoe kidney was suspected, the pathology being confirmed by abdominal ultrasonography.

“…As mentioned previously, the 99mTc-pertechnetate scan is the initial test of choice for detecting MD but may produce misleading results, especially in the adult population. 42,78 Summers et al 78 reported a case in which a 47-year-old male presented with bloody diarrhea, fatigue, nausea, and vomiting. A 99mTc-pertechnetate scan produced noticeable radiotracer uptake in the mid-abdomen.…”

Meckel’s diverticulum: misdiagnosis and late presentation

Meckel's diverticulum (MD) is a congenital anomaly of the gastrointestinal (GI) tract, occurring due to the incomplete obliteration of the omphalomesenteric duct during embryogenesis. Depending on the patient's age and symptomatology at presentation, scintigraphy is often the initial test of choice to detect MD. However, an increased incidence of false positive and negative tests has made MD difficult to diagnose in older children as well as in adults. MD can present in the older population with symptoms such as GI bleeding and anemia, which may mimic other GI pathologies, such as appendicitis, Crohn's disease, and Littré's hernia. Early diagnosis and appropriate management of symptomatic diverticula are vital to the prevention of complications, such as malignancy. The management of symptomatic MD is accomplished through diverticulectomy. Robijn et al proposed a scoring system based on the evaluation of the risk of complications of a nonresected MD against the complications that arise from resection. They suggested that patients with an asymptomatic MD and a risk score , 6 should be left alone, while a risk score. 6 indicates the need for resection. The aim of this study was to provide a review of the literature on MD, with an emphasis on the late presentation and misdiagnosis of this congenital anomaly.

Meckel’s Scan: Pitfall in Patients With Active Small Bowel Bleeding

Potential for a false-positive Meckel's scan is highlighted in this patient with intermittent, low-volume small bowel bleeding. Meckel's scan showed late appearance of focal activity mimicking a positive diverticulum finding. This was secondary to extravasated tracer during a coincidental bleeding as shown by a Tc-99m tagged red blood cell scan obtained 2 days earlier. Inaccurate diagnosis of Meckel diverticulum was avoided by: 1) noticing the late appearance in relationship to the gastric uptake, and 2) showing motility of the focus on delayed dynamic imaging that confirmed transit of extravasated tracer along the small bowel with peristalsis. Subsequent capsule endoscopy showed a bleeding ulcer in the ileum.
