A 16-year old man with an intradural extramedullary arachnoid cyst in the spine: a rare case

Background: Spinal intramedullary cysts present a radiological dilemma. We present a rare case of a conus intramedullary arachnoid cyst and report on its differentiating features and management. Case Description: We report a case of a 30-month-old child who presented with decreased gluteal sensation and urinary dribbling for 6 months. Apart from some slowness in walking, the power was normal in all four limbs. Imaging showed a non-enhancing, T2-weighted hyperintense 12 × 8 mm conus intramedullary cyst without any edema. A T12-L1 laminotomy followed by marsupialization of the cyst was done. Histopathology was suggestive of an arachnoid cyst. The postoperative course was uneventful with improvement in muscle strength and achievement of regular milestones. We also present the pertinent review of the literature to date. Conclusion: Intramedullary arachnoid cysts are a rare entity and should form the differential diagnosis for cysts presenting in the conus medullaris. Simple decompressive options may suffice for symptomatic cases and radical excision may be avoided. A high index of suspicion is essential considering the subtle nature of presenting symptoms.

Abstract OBJECTIVE A rare case of cerebellopontine angle arachnoid cyst manifesting as hemifacial spasm (HFS) is reported. The patient is a 42-year-old woman with 10-month history of left HFS. A preoperative magnetic resonance imaging scan showed a well-demarcated area, hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging, in the left cerebellopontine angle, without contrast enhancement, resembling an arachnoid cyst. METHODS The cyst was excised with microneurosurgical technique and the facial, vestibular, and acoustic nerves were completely decompressed from the arachnoid wall. RESULTS The postoperative course was uneventful, and the left HFS disappeared immediately. Histologically, the cyst wall was a typical arachnoidal membrane. Ten months after surgery, the patient is symptom free. CONCLUSION It is well-known that in approximately 10% of cases, trigeminal neuralgia can be caused by a space-occupying mass. However, the fact that HFS can also be caused by organic lesions as well as neurovascular compression is less well-known. Although the occurrence of tumor compression causing HFS has been previously recognized, cerebellopontine angle cysts have very rarely been described. The observation of a patient with a cerebellopontine angle arachnoid cyst causing HFS prompted us to review the literature relative to HFS caused by an organic lesion rather than neurovascular compression.

The intraspinal enterogenous cyst, also called an neurenteric cyst, is a rare congenital disease. It was reported to be local to the C1 to L2 spinal segments, with the majority located in the cervicothoracic region. Most patients present with symptoms of progressive focal pain, myelopathic signs or radicular symptoms. We report a rare case of thoracic spinal intradural extramedullary enterogenous cyst with rapidly progressive weakness of both lower extremities. Additionally, we analysed the literature concerning the clinical features, diagnosis and prognosis of this disease.

Suprasellar Arachnoid Cyst

Abstract The arachnoid cyst is a lesion commonly encountered in neurosurgery, especially in pediatric pathology. We are presenting the case of an adult patient with a suprasellar arachnoid cyst with giant perimesencephalic and mesial temporal extension discovered incidentally, where there is a discrepancy between the spectacular neuroimaging and the non-specific symptomatology. Some of the physiopathological mechanisms which led to the evolution of the cyst will also be presented.
