“…According to the medical literature, cases of arachnoid cysts have run in families (Familial cases) suggesting that a genetic predisposition may play a role in the development of arachnoid cysts in some individuals. 3 Most arachnoid cysts are found incidentally and remain constant in size, leading many physicians to recommend conservative treatment. When no symptoms are present, no treatment may be necessary and affected individuals may be periodically monitored.…”

“…MRI is the most preferred imaging modality in the diagnosis of arachnoid cysts [1,4,7,10]. In addition, kinematic MRI may be helpful in detecting the presence of communications between the cyst and the subarachnoid space [1]. Arachnoid cysts demonstrate, as seen in our case, a homogeneous signal pattern like that of cerebrospinal fluid signal intensity on T 1 - and T 2 -weighted images, and without contrast enhancement on T 1 -weighted postcontrast images.…”

Noncommunicating spinal intradural extramedullary arachnoid cysts are an extremely rare cause of spinal cord compression. An 8-year-old boy presented with progressive paraparesis. Magnetic resonance imaging revealed a posterior intradural extramedullary arachnoid cyst extending from T₁₁ to L₃ vertebral bodies. The multilevel noncommunicating cyst was totally removed by simple delivery without rupture through a single-level laminoplasty. To our knowledge, no such case has been reported in the literature.

“…Intradural SACs may be intramedullary or extramedullary. SACs are usually located at the thoracolumbar region 1. They are generally asymptomatic.…”

SUMMARYA 38-year-old woman presented with a 12-month history of subjective weakness and pain in her legs. Thoracolumbar MRI revealed two spinal intradural cystic lesions at T5-6 and T11 levels, respectively. The lesion located at the T5-6 level was heterogeneously hyperintense on T2-weighted images and heterogeneously hypointense on T1-weighted images. This lesion showed high signal intensity on diffusion weighted MRI (DWI) and low signal intensity on apparent diffusion coefficient images (ADC). According to the MRI findings, we reported this tumour as a spinal epidermoid cyst. The pathology result suggested that the lesion was an epidermoid cyst. The second intradural lesion, at the T11 level, showed a hypointense signal on T1 and hyperintense signal on T2 images. However, in contrast to the superior lesion, this lesion was hypointense on DWI and hyperintense on ADC. We evaluated the second lesion as an arachnoid cyst according to the MRI findings. BACKGROUND
