Follicular Thyroid Carcinoma Metastases on Round Ligament of Liver.

ABSTRACT: We describe a case of a 69-year-old woman with follicular thyroid cancer of long evolution, with thyroidectomy 20 years before, who had remained clinically stable until now, when she started to present abnormal levels of serum thyroglobulin. An 123I whole-body scan showed a high uptake in the upper right half of her abdomen, and an 18F-FDG PET/CT located this focus at the liver's round ligament. Pathology findings after surgery showed the focus to be a differentiated thyroid cancer metastasis. This is an unusual presentation of differentiated thyroid cancer metastasis.

Spatial anatomy of the round ligament, gallbladder, and intrahepatic vessels in patients with right-sided round ligament of the liver.

PURPOSE: To analyze the vascular structure of the liver in patients with a right-sided round ligament. METHODS: We reviewed 16 patients with a right-sided round ligament and 3 polysplenia and situs inversus patients with a left-sided round ligament who underwent multidetector row CT with contrast media. The patient population consisted of 13 men and 6 women (mean 62 years). We analyzed the axial and volume-rendered images for the location of the round ligament, gallbladder, portal veins, hepatic veins, and hepatic artery. The following imaging findings for the patients with polysplenia and situs inversus were horizontally reversed. RESULTS: The prevalence of a right-sided round ligament with and without polysplenia was 75 and 0.11 %, respectively. The gallbladder was located to the right, below, and left of the round ligament in 27.7, 38.8 and 33.3 %, respectively. Independent branching of the right posterior portal vein was noted in 57.8 %. PV4 was difficult to identify in 36.8 %. The middle hepatic vein was located to the left of the round ligament. Two branching patterns for the lateral and medial branches of the right anterior hepatic artery were noted: the common (44.4 %) and separated types (55.5 %). Both of the right anterior hepatic artery and portal vein ramified into two segments; the lateral segment with many branches and the medial segment with a few branches. CONCLUSIONS: The right-sided round ligament divided the right anterior section into the lateral and medial segments based on the portal vein and hepatic artery anatomy.

Hemangiomas are benign vascular tumors, whose origin comes from the embryonic mesodermal tissue remains. The liver is the most common location. Its location in the teres ligament is extremely rare. This is a 59 years old male admitted because of episodes of epigastric pain for six months. A CT scan and MRI demostrated a 2 cm diameter lesion located near the Teres ligament. Laparoscopic resection was performed. Hemangiomas are the most common benign solid tumors located in the liver. They represents 73% of all benign liver tumors. MRI is the imaging of greater certainty for diagnosis. The Teres ligament (ligamentum teres hepatis) is a fibrous cord resulting in obliteration of the umbilical vein. The location of hemangiomas in this region is extremely rare but should be considered and should make the differential diagnosis with a pedicled hepatic hemangioma or gastointestinal stromal tumors.
