Foreign Body Granuloma Caused by Surgical Suture Material Mimicking Lymph Node Recurrence Detected by Delayed Phase FDG-PET/CT Imaging

New face and…tail of gossypiboma

“…Numerous cases of postoperative abdominal granulomas of large sizes are described in the medical literature [13,14,15,16]. Granuloma is formed more commonly due to non-absorbable suture material, such as silk and polyfilament threads [13,14], but also surgical sponges [16]. The clinical importance of their differentiation especially increases in patients who have undergone surgery for neoplasms, because they create imaging findings that may be confused with a malignant lesion recurrence at a previous operative site [15], as occurred in our case.…”

“…Other, at first glance seem less dramatic, manifestations of a reaction to a foreign body, implanted or inadvertently left in the abdominal cavity, include granulomas. Numerous cases of postoperative abdominal granulomas of large sizes are described in the medical literature [13,14,15,16]. Granuloma is formed more commonly due to non-absorbable suture material, such as silk and polyfilament threads [13,14], but also surgical sponges [16].…”

Laparoscopic excision for small intestinal mesenteric tumour diagnosed Schloffer tumour

“…[ 4 ] Another case required pancreaticoduodenectomy after ascending colon cancer because the Schloffer tumour resembled malignancy relapse. [ 5 ] Therefore, distinguishing post-operative recurrence from Schloffer tumours is difficult when a growing mass is observed at the previous surgical site. In fact, there have been no reports of Schloffer tumours being diagnosed before surgery except for the abdominal wall, further highlighting the difficulty of pre-operative diagnosis.…”

Intra-abdominal suture granulomas masquerading as colon carcinoma: a case report

“…[23][24][25][26][27] Intra-abdominal suture granulomas radiologically are mainly mistaken as a primary malignancy or as the recurrence of the previously diagnosed cancer as mentioned by various researchers. 3,4,[28][29][30][31] Therefore, its definite diagnosis is only made after the surgical excision of the lesion followed by histopathological examination. Histopathology shows a granulomatous response marked by histiocytes and foreign body type giant cells surrounding and engulfing the suture material.…”
