“…Occasionally, the intradiploic cysts may attain an enormous size and extend into the sphenoid sinus, orbits, infratemporal fossa, pterygomaxillary region, nasal cavity, and nasopharynx [1] , [2] , [6] . There are rare case reports in the literature that show different clinical manifestations and imaging findings of symptomatic intradiploic cysts.…”

“…There are rare case reports in the literature that show different clinical manifestations and imaging findings of symptomatic intradiploic cysts. Large intracranial arachnoid cysts rarely extend into the sphenoid sinus, causing clinical manifestations of proptosis, headache, and nasal symptoms and imaging appearance of the sphenoid mucocele [1] , [2] , [8] , [9] . The smaller nontraumatic asymptomatic intraosseous arachnoid cysts do not require surgical management unlike the large or growing lesions with significant clinical implications [5] , [6] , [10] .…”

“…Intracranial arachnoid cysts are benign cerebrospinal fluid (CSF)-containing cysts that are generally developmental in nature and are rarely post-traumatic or posthemorrhagic [1] , [2] . These cysts most commonly occur in the middle cranial fossa and can occasionally be symptomatic.…”

The intradiploic arachnoid cysts are rare radiological entities which are generally post-traumatic in nature and occur mostly in occipital region. We present a rare case of non-traumatic, asymptomatic intradiploic cyst of the greater wing of sphenoid in an elderly patient. The CT and MR imaging confirmed an intraosseous multiloculated cystic lesion which showed communication with the cerebrospinal fluid in anterior temporal fossa, through the small bony defects.

“…They are thought to result from head injury, hemorrhage, meningitis, tumors, or skull base surgery. 10,11 These conditions can cause tearing of the dura, whereas increased intracranial pressure causes the arachnoid membrane to invaginate in an osseous defect, causing a posttraumatic intraosseous arachnoid cyst. 5 In such cases, there is obviously no relationship between the arachnoid cyst and the natural foramen of the skull base.…”

We present a rare finding of the arachnoid matter invaginating into the base of middle cranial fossa and creating an abnormal space. Presented entity was incidentally found in head CT scan of 12-year-old male. Based on the radiological characteristics in CT scans and MR images, the diagnosis of intradiploic arachnoid cyst (AC) was suggested. After surgical intervention and histopathological analysis of the specimen, the diagnosis was confirmed. We assume this is the first description of large intrasphenoid AC without any traumatic or iatrogenic cause. The literature provides many different terms for the phenomenon. We are proposing the term intradiploic arachnoid diverticulum as the more accurate for capturing the essence of the phenomenon. It provides clear differentiation of the entities from classical arachnoid cysts since they are of different anatomical localization (intradural vs. extradural) and etiopathogenesis. Management with arachnoid diverticulum is not yet established, but observation with serial imaging studies should be recommended as primary management in case of asymptomatic cyst. When cyst is symptomatic, surgical treatment may be required.
