Abstract: Greater omental torsion is a rare entity that can cause acute abdominal pain, may
mimick other abdominal pathologies, and is difficult to be diagnosed preoperatively. We

present a case of a male patient with greater omental torsion mimicking the symptoms of

acute appendicitis. A 31-year-old male patient presented with right scrotal pain, initially treated
by the urologists, however, 24 h later, he presented right lower quadrant pain, with
characteristics of acute appendicitis. After finding in ischemic inflammatory mass on

McBurney incision, an exploratory laparotomy was performed, revealing torsion of the greater
omentum. Torsion of the greater omentum can be a cause of acute abdomen and could be

misdiagnosed with acute appendicitis. Preoperative diagnosis is not easy and resection of the
affected tissue is the preferred treatment of choice.

Abstract: Anaplastic thyroid carcinoma is a rare tumor, consisting 1-2% of all thyroid
malignancies and presenting a high mortality rate. Median survival for patients undergoing

primary surgery is approximately 6.6 months. We present a case of a patient treated with R0
resection, including total thyroidectomy and lymphadenectomy of levels III, IV, VI and VII after

cervical lymph node mapping, oral 131I administration, and radiotherapy. Proper preoperative
research, R0 resection and relatively early diagnosis, led to good prognosis, as the patient is

currently totally disease-free, twelve months postoperatively.
