Solitary aneurysm of the filum terminale artery: A case report and review of the literature

چکیده
BACKGROUND We report a rare case of aneurysmal dilatation of filum terminale artery after resection of filum terminal myxopapillary ependymoma. CASE DESCRIPTION The authors report a rare aneurysmal dilatation of the filum terminale artery following removal of a filum terminal myxopapillary ependymoma in a 10-year-old male. The patient presented with 6-month history of increasing back pain without a focal neurological deficit. Magnetic resonance (MR) showed an intradural filum terminale lesion that was completely excised. Three months later, the MR again revealed a lesion involving the filum terminale. During the second surgery, however, an aneurysmal dilation of the filum artery was found, which was coagulated and resected. Following the secondary surgery, the patient's symptoms gradually resolved, and he remains intact. CONCLUSION Although rare, a true aneurysm after spinal surgery should be considered among the differential diagnostic consideration in the region of the filum terminale.

Giant Cell Ependymoma of The Filum Terminale: A Case Report
Ependymomas accounts for about 2%–6% of CNS and 60%–70% of spinal cord tumors. Several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. In spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. This report presents a case of giant cell ependym...

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that most commonly arises from the visceral or parietal pleura. Solitary fibrous tumor with a primary site in the filum terminale has not been reported previously in the literature. Here we report a case of SFT occurring in the filum terminale. The characteristic imaging feature of this tumor is hypointensity on T2-weighted images. Even tho...

Hepatic artery aneurysms are a rare cause of upper gastrointestinal hemorrhage and may represent significant problems in both diagnosis and management. We report a 70 year old patient with gastrointestinal bleeding from a fistula between a 7 cm hepatic artery aneurysm and the duodenum. He underwent successful surgical management with endoaneurysmorrhaphy and duodenal wall repair.
