Schwannoma in and around the porta hepatis: radiological features in eight cases and literature review

Benign hepatic schwannoma in a patient with chronic hepatitis B infection: A case report

“…The nerves responsible for the bile duct system emanate from the hepatic nerve plexus. Schwannoma of the liver can arise from several sympathetic and parasympathetic nerves that run along the hepatic artery and interlobular connective tissue [ 10 ]. When observed under an optical microscope, they are divided into Antoni A and Antoni B areas with different characteristics.…”

CT features of schwannoma in the hepatoduodenal ligament with portal vein compression: A case report

“…CT typically reveals a hepatoduodenal ligament mass in patients with schwannomas in this ligament. It has been noted that different components (such as the Antoni A and B sections) inside schwannomas exhibit different attenuations and signals on CT and MRI scans [1] . Tumor extension along the hepatoduodenal ligament, compressing IVC without obstruction, was suggestive of a slow-growing benign behavior.…”

“…The tumor was growing along the hepatoduodenal ligament, compressing the bile ducts and blood vessels without obstruction, which suggests that it has an extrahepatic origin and is slow-growing and benign. It has been reported that both CT and MRI show variable attenuations and internal signals based on the Antoni A and B regions within the schwannoma [1] . The case shows target-like gradually increasing enhancement that suggestive of Antoni A histology, The appears of the mass are different from other reported.…”

“…Schwannomas are benign, encapsulated tumors that originate from Schwann cells in the nerve sheath. Schwannomas arise from aberrant division and proliferation of Schwann cell [1] . Tumors are most commonly found in the lower limbs, but can be found in any part of the body, abdominal schwannomas are rare [2] .…”

Case Report: Upper limb dysfunction may be caused by chest wall mass excision: An enlightenment from a special case

“…A schwannoma is a tumor originating from Schwann cells of the nerve sheath ( 14 ). It can affect all body parts, but it is most localized in the head and neck, and in the flexor aspect of the limbs, it can also localize, where many nerves are distributed ( 15 , 16 ). Chest walls with adjacent axillary schwannomas are extremely uncommon.…”
