“…3,8,9,21,26,29,50,59 In our own practice, 38 we have observed that patients with symptomatic AC-associated subdural hygromas will frequently experience a complete and lasting spontaneous resolution of their neurological symptoms if managed without surgery, even in cases with transient symptoms of elevated intracranial pressure. For this reason, we suggest that the decision to surgically treat symptomatic hygromas associated with ACs should be made carefully and only after the generally benign natural history of this condition is considered.…”

OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

“…Some authors have suggested that surgical treatment of subdural hygromas associated with arachnoid cysts is always or almost always necessary, 3,7,8,28,29,59,72 with some going so far as to call nonsurgical management inappropriate. 20 Others have even suggested that hygromas, since they have symptoms of elevated ICP, should be considered potentially life threatening.…”

“…3,6,9,11,12,15,18,23,26,28,42,58,62,68,82 Most prior reports have advocated surgical treatment for arachnoid cyst-associated subdural hygromas. 3,7,8,20,28,29,59,72 We have observed that patients with a symptomatic subdural hygroma associated with an arachnoid cyst will frequently experience complete and lasting spontaneous resolution of their neurological symptoms if managed without surgery. We report our recent experience with managing arachnoid cyst-associated subdural hygromas without surgery and suggest that the often benign natural history of this condition should be considered when making treatment decisions.…”

Object Arachnoid cysts may occasionally be associated with subdural hygromas. The management of these concurrent findings is controversial. Methods The authors reviewed their experience with arachnoid cysts and identified 8 patients with intracranial arachnoid cysts and an associated subdural hygroma. The medical records and images for these patients were also examined. Results In total, 8 patients presented with concurrent subdural hygroma and arachnoid cyst. Of these 8 patients, 6 presented with headaches and 4 had nausea and vomiting. Six patients had a history of trauma. One patient was treated surgically at the time of initial presentation, and 7 patients were managed without surgery. All patients experienced complete resolution of their presenting signs and symptoms. Conclusions Subdural hygroma may lead to symptomatic presentation for otherwise asymptomatic arachnoid cysts. The natural course of cyst-associated subdural hygromas, even when symptomatic, is generally benign, and symptom resolution can be expected in most cases. The authors suggest that symptomatic hygroma is not an absolute indication for surgical treatment and that expectant management can result in good outcomes in many cases.

“…The number of patients with ACs tends to decrease with age [4,30] . This fact suggests that the cyst wall may rupture by minor head injury, excessive breathing, coughing, or sport activities [31] . This resolution may occur silently during a lifetime or could be symptomatic [5] .…”

Arachnoid cysts (ACs) are frequently encountered in pediatric neurosurgical practice. Their natural history and optimum treatment are not well determined. The authors describe a resolution of asymptomatic middle fossa AC after trivial head trauma in a 7-year-old child. Intracystic bleeding was noticed on interval MRI. Serial MRI follow-up demonstrates stages of resolution of the AC that did not require surgical intervention. Few cases of nonsurgical AC disappearance have been reported, much fewer with trauma as a triggering factor. Here, we present the stages of resolution in images.
