“…It is of interest to note that a meningeal space between the meningeal and periosteal dura, named the interperiosteodural space, part of the extradural neural axis compartment was anatomically demonstrated at the level of the cavernous sinus and its continuity toward the foramen magnum, at the dural folds of the jugular foramen, and the level of the falx cerebri. [ 7 , 9 , 15 , 51 ] A few reports suggest the existence of a transdural passage, and absorption of CSF is observed at the level of the falx cerebri and tentorium. [ 28 , 51 ] This could explain the high physiological prevalence of CSF in subdural collections.…”

Background: Rare cases of biconvex hematomas splitting the convexity dura mater were reported and denominated interdural hematoma (IDH). Due to their rarity, little is known about their radiological characteristics, and in most cases, their invasive management with craniotomy and dural membrane excision is unnecessary. Case Description: We report here a case of single burr-hole endoscopic evacuation of an IDH and its complete resolution after the 6-month follow-up imaging. The literature review reveals 11 reported cases of IDH. Most of them are male and the mean age is 65 years (range 51–90). Most of the reported IDHs were misdiagnosed as epidural hematoma or meningioma, and therefore, they have been managed invasively through craniotomy with dural excision. Diagnosis of the interdural nature was confirmed macroscopically during surgery in all cases and histology was reported for 6 cases. Image analysis found a double dural beak sign and biconvex shape on coronal planes, subarachnoid space enlargement at the collection extremities, and irregular thick inner wall as common radiological aspects of the IDH. Conclusion: IDH is a rarely reported and often misdiagnosed dural hematoma subtype. Its invasive treatment through craniotomy is likely related to its unknown radiological characteristics. We review and raise awareness about potentially unique radiological anatomy that could avoid unnecessary invasive treatment. Moreover, we report the first case of endoscopically evacuated IDH with long-term follow-up imaging showing complete resolution.

“…1,4 The CSF pathways through the dura mater have been reported at other sites of the intracranial cavity with associated pathological conditions. [8][9][10] In human dry skulls, the intracranial surface of the AFF is commonly observed to be rugged to varying degrees, whereas the orbital surface is commonly smooth (Fig. 1).…”

ObjectiveTo date, only limited information regarding the anterior cranial fossa floor (AFF) and the appearance of sites of dehiscence and potential channels has been available. We aimed to evaluate this region with thin section magnetic resonance imaging (MRI).Patients and MethodsA total of 65 patients underwent thin-sliced coronal T2-weighted MRI. The AFF was divided into 3 parts for analysis: the anterior, middle, and posterior.ResultsDehiscences were identified in 84.6% of 65 patients with apparently transmitting channels. In 49.2% of the patients, the dehiscences were located in the anterior part, whereas they were located in the middle and posterior parts in 52.3% and 12.3%, respectively. The morphology and number of these dehiscences were highly variable. In 12.3%, channels in the dehiscences were distributed extradural. Statistically, dehiscences were more frequently identified on the left side in any part of the AFF.ConclusionsWith thin-sliced, coronal T2-weighted MRI, dehiscences were frequently identified in the anterior two-thirds of the AFF. Further study is warranted to determine the role of AFF channels and dehiscences, including possibly for cerebrospinal fluid drainage.
