Background: Nerve sheath myxoma is a rare benign soft tissue tumor. Intraspinal nerve sheath myxomas are rare. Only 8 cases of intraspinal nerve sheath myxoma have been reported to date, and no case of nerve sheath myxoma has been reported in the cervical spinal canal. Herein, we reported the first case of intradural extramedullary nerve sheath myxoma in the cervical spinal canal of a 57-year-old man, including its complete clinical course and radiological findings.Case Presentation: A 57-year-old male patient presented with numbness in his left finger without any obvious inducement for 3 years. CT and contrast-enhanced magnetic resonance imaging (MRI) of the spine were performed. Based on the radiological examinations, a diagnosis of schwannoma was initially made. However, nerve sheath myxoma was finally confirmed by histopathological and immunohistochemical examinations. Complete tumor excision at the C1-2 level was performed. Then, the patient recovered well, and the numbness of his left finger disappeared during the later follow-up after the surgery.Conclusion: Nerve sheath myxoma should receive diagnostic consideration for an extramedullary subdural lesion that is a clear boundary mass characterized by isointensity on T1-weighted images, heterogeneous intensity on T2-weighted images, obvious peripheral enhancement, and a growing tendency toward the intervertebral foramen.

Objective.To evaluate the forward shifting of cervical spinal cords in different segments of patients with Hirayama disease to determine whether the disease is self-limiting.Methods.This study was performed on 11 healthy subjects and 64 patients. According to the duration, the patients were divided into 5 groups (≤1 year, 1-2 years, 2-3 years, 3-4 years, and ≥4 years). Cervical magnetic resonance imaging (MRI) of flexion and conventional position was performed. The distances between the posterior edge of the spinal cord and the cervical spinal canal (X), the anterior and posterior wall of the cervical spinal canal (Y), and the anterior-posterior (A) and the transverse diameter (B) of spinal cord cross sections were measured at different cervical spinal segments (C4 to T1).Results.In cervical flexion position, a significant increase inX/Yof C4-5 segments was found in groups 2–5, the C5-6 and C6-7 segments in groups 1–5, and the C7-T1 segments in group 5 (P<0.05). The degree of the increasedX/Yand cervical flexionX/Yof C5-6 segments were different among the 5 groups (P<0.05), which was likely due to rapid increases inX/Yduring the course of Hirayama’s disease.Conclusion.TheX/Ychange progression indicates that Hirayama disease may not be self-limiting.

Abstract Aim: Ependymomas compose the majority of all intradural intramedullary spinal lesions. Filum terminale lesions are rarely associated with syringomyelia. Here we describe a case of extramedullary myxopapillary ependymoma associated with extensive syringomyelia located in the filum terminale. Material and Methods: A 34-year-old man admitted to our clinic with complaints of bilateral leg weakness, back pain and urinary dysfunction. The magnetic resonance imaging (MRI) of the patient showed us a contrast enhanced intraspinal mass at the level of L2 with a syringomyelia extending from L2 level to Th7 level. Results: The patient was operated via lumbar laminoplasty and tumor was totally resected. Conclusion: The removal of tumor is also sufficient for the resolution of syringomyelia and no additional procedure is essential for the treatment of syringomyelia in such cases. This is the first case of extramedullary tumors of the cauda equine with extensive syringomyelia.

Sclerosing lipogranuloma is a rare benign disease, representing a peculiar granulomatous reaction of fatty tissue. The majority of cases are secondary to injection of exogenous foreign bodies, such as silicone, paraffin, mineral, or vegetable oils. To the best of our knowledge, we present the first case of a silicone-induced penile lipogranuloma in a 52-year-old man evaluated with a multiparametric magnetic resonance imaging (MRI) protocol, including diffusion-weighted imaging, magnetization transfer imaging, and dynamic contrast-enhanced MRI. MRI of the penis by combining both conventional and functional information represents an important imaging tool in the preoperative workup of silicone-induced penile lipogranuloma.

Craniopharyngiomas (CPs) are rare benign epithelial tumours. Brain arteriovenous malformations (AVMs) are also rare lesions occurring in young adults. The appearance of both these lesions in the same patient is rare. A 42-year-old patient presented with headaches for 3 months and a progressive decrease in his visual acuity. Bitemporal hemianopsia was detected in the visual field. Magnetic resonance imaging (MRI) revealed a tumour with cystic and solid components located in the suprasellar region and AVM in the right temporal lobe. AVM (Martin–Spetzler grade III) was visualised using digital subtract angiography (DSA), which was fed from the right middle cerebral artery and drained through the sigmoid sinus via the inferior petrosal sinus. The patient was operated with enlarged right frontotemporal craniotomy. AVM nidus was totally removed at the first operation. Embolisation was not preferred before the AVM surgery. After 3 days, sylvian dissection was performed using the same craniotomy. The tumour was completely removed via the carotid cistern by making sharp dissection from the infundibulum. Post-operatively, the patient showed normal neurological examination and significant improvement in his visual field examination. There was no residual/recurrent tumour or AVM on contrast-enhanced MRI and DSA at post-operative 6 months. Histopathological examination revealed AVM in the first operative material and papillary-type CP in the second.  The coexistence of these two rare pathologies has previously been reported in only one patient. This is the first case of surgical resection of CP and AVM using the same craniotomy.

ABSTRACT Introduction Yellow-colored cerebrospinal fluid (CSF) suggestive of xanthochromia can be due to elevated CSF protein and can be one of the causes of papilledema. Observation We observed a 55-year-old lady with papilledema with yellow-colored CSF which was hypercoagulable along with elevated CSF protein and no cells. Her systemic and nervous system examination was unremarkable except for the eye findings. Her contrast-enhanced brain magnetic resonance imaging (MRI) showed multiple meningiomas, and on imaging of the spine, she had multiple contrast-enchancing intradural, extramedullary lesions. Her eye findings were attributed to Froin syndrome found in patients with spinal tumors. Conclusion Our case stresses the need to keep the possibility of Froin syndrome in mind while evaluating patients with papilledema and it may be pertinent to perform a spinal imaging, especially when no apparent cause for papilledema is found.

Intradural Extramedullary Tumour

Tumour excision and laminoplasty are commonly performed as surgical treatment of extra vertebral extension of cervical schwannoma. It is worth knowing that the conventional technique of multilevel laminectomy may hinder younger patients in the long-term. This article reports a 30-year old man with an intradural-extramedullary tumour which extended from C4 to T1 that underwent modified laminoplasty.  This modified technique is preferable in maintaining the anteroposterior diameter of spinal canal as well as reducing the displacement of guttered laminae

Abstract Background Mature presacral (retrorectal) teratoma is very rare. We report a case in which a mature retrorectal teratoma in an adult was successfully treated with laparoscopic surgery. Case presentation A 44-year-old woman was diagnosed with a presacral tumor during a physical examination. Endoscopic ultrasonography (EUS) revealed a multilocular cystic lesion; the lesion was on the left side of the posterior rectum and measured approximately 30 mm in diameter on both contrast-enhanced pelvic computed tomography (CT) and magnetic resonance imaging (MRI). The presumptive diagnosis was tailgut cyst. However, the histopathological diagnosis after laparoscopic resection was mature teratoma. It is still difficult to preoperatively diagnose mature retrorectal teratomas. Conclusions Laparoscopic resection of mature retrorectal teratomas is a feasible and promising method that is less invasive and can be adapted without extending the skin incision.
