Cauda equina syndrome caused by filum terminale lipoma: magnetic resonance imaging features and surgical treatment

DOI: 10.1590/S1679-45082017AI3882 A 36-year-old woman with a sudden history of low back pain radiating into the right lower extremity. The physical examination revealed paraparesis, saddle anesthesia and urinary incontinence. Magnetic resonance imaging revealed lipoma of the filum terminale (hyperintense sign within the filum terminale) (Figure 1). The patient underwent surgery without delay wi...

[Cauda equina syndrome caused by paraganglioma of the filum terminale].

Paragangliomas are neuroendocrine tumors that originate from cells migrating from the neural crest. They have a diverse localizations, and are common in the head, neck, mediastinum or retroperitoneum. Their growth in the filum terminale region is very infrequent. We report the case of a patient who suffered an acute cauda equina syndrome. We give a detailed description of the diagnostic process...

Spontaneous Hemorrhage of a Spinal Ependymoma in the Filum Terminale Presenting with Acute Cauda Equina Syndrome: Case Report

We present a rare case of spontaneous hemorrhage of a spinal ependymoma in the filum terminale presenting with acute cauda equina syndrome. A 16-year-old male presented with a sudden onset of severe back pain that began 10 days before hospitalization. This symptom progressed, followed by development of decreased sensation in the lower extremities, bladder dysfunction, and motor weakness that ad...

Clinical features of cauda equina tumors requiring surgical treatment.

In this study, we evaluated the clinical features of cauda equina tumors requiring surgical treatment. Medical records of 28 patients with cauda equina tumors (13 men and 15 women) undergoing surgical treatment were retrospectively reviewed. The majority of histological diagnoses indicated schwannoma (23 cases, 82%), and the remaining 5 indicated ependymoma, neurofibroma, meningioma, and gangli...
