“…Some of these cysts are quiescent throughout life and some remain dormant for decades before manifesting clinically. 3,4,6 Arachnoid cysts involving the cervical region, as in our case, are also extremely rare. 2,10 Our patient is the third case report of a symptomatic spinal intramedullary arachnoid cyst and the second in the pediatric age group.…”

The authors report their experience in successfully treating a 4-year-old girl who presented with sudden onset of quadriparesis that lasted for 20 days. Magnetic resonance (MR) imaging of the spine revealed an intramedullary cystic lesion extending from C-4 to C-6. A C4-6 laminectomy was performed followed by a median myelotomy. The cyst was decompressed and most of the cyst wall was excised. The histopathological findings were consistent with those of an arachnoid cyst. By postoperative Day 3, power had gradually returned to normal in all her limbs. On follow-up reviews at 2 and 17 months, the results of her neurological examinations remained normal. Follow-up MR imaging of the spine at 17 months revealed an intramedullary residual cystic lesion extending from C-5 to C-6, without any mass effect. An intramedullary arachnoid cyst should be considered in the differential diagnosis of an intramedullary cystic lesion.

“…None of these showed worsening of the preoperative neurological deficits. Instead all the patients presented a clear improvement during the first weeks following the procedure, which was independent from the duration or severity of symptoms [3,4,[6][7][8][9][10][11][13][14][15][16][17][18]. The authors report the only published case of intramedullary adult arachnoid cyst with neurological stability during follow-up (five years), and managed with a wait and scan approach.…”

“…All cases of purely intramedullary arachnoid cysts reported in the literature showed a growth overtime accompanied by sudden neurological deterioration, requiring immediate surgical evacuation [3,4,[6][7][8][9][10][11][13][14][15][16][17][18]. To date, there is no existing literature on a quiescent intramedullary arachnoid cyst detected incidentally in an asymptomatic subject [10].…”

Spinal arachnoid cysts are uncommon benign lesions that occur in the spinal axis, and can cause spinal cord or nerve roots compression and may become clinically relevant.The authors report a 49-year-old woman who presented progressive onset of cervical pain with distal paraesthesia of the upper limbs associated to an intramedullary arachnoid cyst in the mid-cervical spine diagnosed by MRI.From the literature review, only six cases in patients over 18-year-old were found, all with thoracic location and one with cervical extension, and all were submitted to decompressive surgery.The authors described the first intramedullary arachnoid cyst with a wait and scan approach.
