The aim of the present study was to demonstrate the incidence of spinal cerebrospinal fluid (CSF) leaks in patients with nontraumatic intracranial subdural hematoma (SDH) and determine clinical parameters favoring such leaks. This retrospective study was approved by the institutional review board. Patients diagnosed with nontraumatic intracranial SDH who underwent computed tomography (CT) myelography between January 2012 and March 2018 were selected. 60 patients (male: female, 39:21; age range, 20–82 years) were enrolled and divided into CSF leak-positive and CSF leak-negative groups according to CT myelography data. Clinical findings were statistically compared between the two groups. Spinal CSF leak was observed in 80% (48/60) of patients, and it was significantly associated with an age of <69 years (p = 0.006). However, patients aged ≥69 years also had a tendency to exhibit spontaneous intracranial hypotension (SIH)-induced nontraumatic intracranial SDH (60.87%; 14/23). Therefore, CT myelography is recommended to be performed for the evaluation of possible SIH in patients with nontraumatic intracranial SDH, particularly those aged <69 years. Patients aged ≥69 years are also good candidates for CT myelography because SIH tends to occur even in this age group.

Object Spontaneous intracranial hypotension is an important cause of headaches and an underlying spinal CSF leak can be demonstrated in most patients. Whether CSF leaks at the level of the skull base can cause spontaneous intracranial hypotension remains a matter of controversy. The authors' aim was to examine the frequency of skull base CSF leaks as the cause of spontaneous intracranial hypotension. Methods Demographic, clinical, and radiological data were collected from a consecutive group of patients evaluated for spontaneous intracranial hypotension during a 9-year period. Results Among 273 patients who met the diagnostic criteria for spontaneous intracranial hypotension and 42 who did not, not a single instance of CSF leak at the skull base was encountered. Clear nasal drainage was reported by 41 patients, but a diagnosis of CSF rhinorrhea could not be established. Four patients underwent exploratory surgery for presumed CSF rhinorrhea. In addition, the authors treated 3 patients who had a postoperative CSF leak at the skull base following the resection of a cerebellopontine angle tumor and developed orthostatic headaches; spinal imaging, however, demonstrated the presence of a spinal source of CSF leakage in all 3 patients. Conclusions There is no evidence for an association between spontaneous intracranial hypotension and CSF leaks at the level of the skull base. Moreover, the authors' study suggests that a spinal source for CSF leakage should even be suspected in patients with orthostatic headaches who have a documented skull base CSF leak.

✓The authors report a case of a recurrent subdural hematoma (SDH) that was caused by a persistent cerebrospinal fluid (CSF) leak from an L1–2 fistula. A 34-year-old man experienced severe headaches due to SDH, and he underwent aspiration of subdural fluid four times due to recurrent collections. Further evaluation with computerized tomography (CT) myelography demonstrated extradural extravasation of contrast through an L1–2 fistula. The patient underwent an L1–2 laminectomy; a small dural defect with CSF leakage at the left nerve root sleeve was found and was repaired. Following the repair, the patient had no further recurrence of SDH. Recurrent SDH, caused by spontaneous CSF leakage through a lumbar CSF fistula, is extremely rare. In cases of recurrent SDH, radiographic workup with spinal CT myelography should be considered.

✓ Spinal cerebrospinal fluid (CSF) leaks are often implicated as the cause of the syndrome of spontaneous intracranial hypotension, but they have rarely been demonstrated radiographically or surgically. The authors reviewed their experience with documented cases of spinal CSF leaks of spontaneous onset in 11 patients including their surgical observations in four of the patients. The mean age of the six women and five men included in the study was 38 years (range 22–51 years). All patients presented with a postural headache; however, most had additional symptoms, including nausea, emesis, sixth cranial-nerve paresis, or local back pain at the level of the CSF leak. All patients underwent indium-111 radionucleotide cisternography or computerized tomographic (CT) myelography. The location of the spontaneous CSF leak was in the cervical spine in two patients, the cervicothoracic junction in three patients, the thoracic spine in five patients, and the lumbar spine in one patient. The false negative rate for radionucleotide cisternography was high (30%). Subdural fluid collections, meningeal enhancement, and downward displacement of the cerebellum, resembling a Chiari I malformation, were commonly found on cranial imaging studies. In most patients, the symptoms resolved in response to supportive measures or an epidural blood patch. Leaking meningeal diverticula were found to be the cause of the CSF leak in four patients who underwent surgery. In three patients these diverticula could be ligated with good result but in one patient an extensive complex of meningeal diverticula was found to be inoperable. Two patients had an unusual body habitus and joint hypermobility, and two other patients had suffered a spontaneous retinal detachment at a young age. In conclusion, spontaneous spinal CSF leaks are uncommon, but they are increasingly recognized as a cause of spontaneous intracranial hypotension. Most spinal CSF leaks are located at the cervicothoracic junction or in the thoracic spine, and they may be associated with meningeal diverticula. The radiographic study of choice is CT myelography. The disease is usually self-limiting, but in selected cases our experience with surgical ligation of leaking meningeal diverticula has been satisfactory. An underlying connective tissue disorder may be present in some patients with a spontaneous spinal CSF leak.

Objective The objective of this report is to compare computed tomography (CT) and magnetic resonance (MR) myelography with radioisotope cisternography (RC) for detection of spinal cerebrospinal (CSF) leaks. Methods We retrospectively reviewed 12 spontaneous intracranial hypotension (SIH) patients; CT and RC were performed simultaneously. Three patients had MR myelography. Results CT and/or MR myelography identified CSF leaks in four of 12 patients. RC detected spinal leaks in all three patients confirmed by CT myelography; RC identified the CSF leak location in two of three cases, and these were due to osteophytic spicules and/or discs. RC showed only enlarged perineural activity. Only intrathecal gadolinium MR myelography clearly identified a slow leak from a perineural cyst. In eight remaining cases, the leak site was unknown; however, two of these showed indirect signs of CSF leak on RC. CSF slow leaks from perineural cysts were the most common presumed etiology; and the cysts were best visualized on myelography. Conclusion RC is comparable to CT myelography but has spatial limitations and should be limited to atypical cases.

Object Spontaneous and medically induced CSF leaks are uncommonly associated with pituitary adenomas. The aim of this study was to further characterize the clinical scenarios most closely associated with this phenomenon. Methods A review of the literature was conducted to identify all cases of nonsurgical CSF leaks associated with pituitary adenomas. The authors aimed to identify associated risk factors and management strategies used to treat these tumors and repair the CSF leak site. Results Fifty-two patients with spontaneous or medically induced CSF leaks in the setting of a pituitary adenoma were identified from 29 articles published from 1980 through 2011. In 38 patients (73%), CSF rhinorrhea developed following initiation of medical therapy, whereas spontaneous CSF leakage developed as the presenting symptom in 14 patients (27%). The patients' mean age was 42.8 years (range 23–68 years). There were 35 males and 17 females. Forty-two patients (81%) had a prolactinoma, with the remaining patients having the following tumors: nonfunctioning pituitary adenoma (6 patients), growth hormone–secreting adenoma (2 patients), mammosomatotroph cell adenoma (1 patient), and ACTH-secreting adenoma (1 patient). Infrasellar tumor invasion into the paranasal sinuses was specifically reported in 56% of patients. The medical agents associated with CSF leakage were dopamine agonists (97%) and somatostatin analogs (3%). The average time from initialization of medical treatment to onset of rhinorrhea was 3.3 months (range 3 days–17 months). Nonsurgical management was successful in 4 patients, including 1 who had successful resolution with a temporary lumbar drain. Forty-six patients (88%) underwent surgical intervention to treat the CSF leak and/or resect the tumor. In 2 patients, surgery was not performed due to medical contraindications or patient preference. Conclusions Nonsurgical development of CSF rhinorrhea may occur in the setting of pituitary adenomas, especially following favorable response of invasive prolactinomas to initiation of dopamine agonist therapy. Additional cases have been reported as the presenting symptom of a pituitary adenoma and are likely to be related to decreased tumor volume due to intrinsic infarction or hemorrhage, ongoing invasion, and/or increases in intracranial pressure. Surgical repair, preferentially via a transsphenoidal approach, is the recommended initial treatment for definitive repair of the CSF leak and achievement of maximal tumor resection.

Csf Leakage

Spontaneous intracranial hypotension (SIH) is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF) results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdural fluid (hematoma/hygroma). When SIH-related subdural hematoma is present only unilaterally with a concomitant midline shift, making an accurate diagnosis may be challenging, and inadvertent hematoma evacuation may result in further neurologic deterioration. We report a 58-year-old woman with an altered mental status who had visited a local hospital and in whom a brain CT showed a unilateral subdural hematoma with a marked midline shift. She was referred to our department because of her neurologic deterioration after hematoma evacuation. A CT myelography revealed a massive CSF leakage in the entire thoracic epidural space. She made a full neurologic recovery following blood patch therapy. Our case is unique and educational because the suspicion for SIH as an underlying cause of subdural hematoma is warranted in nongeriatric patients not only with bilateral but also unilateral lesions. An immediate search for CSF leakage may be important in cases with failed hematoma evacuation surgery.

Csf Leaks

The common denominator of spontaneous intracranial hypotension (SIH), postsurgical cerebral spinal fluid (CSF) leaks, and postpuncture headache (PPH) is a decrease in CSF volume. The typical presentation is orthostatic headaches, but atypical headaches can be difficult to diagnose and challenging to treat. Management is based on clinical suspicion and characterization of the headache, followed by imaging (noninvasive or invasive). Treatment ranges from conservative to different modalities of epidural blood patches, fibrin glue injections, or surgical exploration and repair. We report 5 cases with great variation in clinical and radiological presentations. Two cases of SIH involved difficult diagnosis and treatment, 2 others featured postsurgical high-flow CSF leaks, and one case presented with a low-flow CSF leak that needed closer evaluation in relation to hardware manipulation. In all cases, recommendations for diagnosis and management of intracranial hypotension were followed, even though in 3 cases the mechanism of trauma was not related to spontaneous hypotension. All cases of headache were resolved. The actual recommendations for SIH are very effective for PPH and postsurgical CSF leaks. With this case series, we illustrate how anatomical and clinical considerations are paramount in choosing appropriate imaging modalities and clinical management.

Underlying Mechanisms

The most common cause of spontaneous intracranial hypotension headache is a cerebrospinal fluid (CSF) leakage, but the underlying mechanisms remain unknown. Intracranial hypotension is characterised by diffuse pachymeningeal enhancement on cranial MRI features, low CSF pressure and orthostatic headaches mostly caused by the dural puncture. We report a 31-year-old woman who presented to our services with reports of continuous severe bifrontal headache, which increased on sitting up and resolved on lying down. MRI of the cervical and lumbosacral spine showed signs of CSF leak; hence, patient was diagnosed with spontaneous intracranial hypotension headache. A CT-guided epidural blood patch was done at L4–5 with fibrin glue injected at the site of leak. The patient’s signs and symptoms improved after the procedure.

The Brain

Postural headache due to low intracranial pressure is a well-known entity and is most commonly encountered following lumbar puncture. It may occur as a consequence of a medical condition (dehydratation, uremia, etc.) but in some cases no precipitating event is apparent and the intracranial hypotension is believed to have developed spontaneously. In such cases the underlying cause of the syndrome is rarely established and treatment is non specific. We describe three patients with spontaneous intracranial hypotension examined with MRI of the brain. Women are more commonly affected than men in the third or fourth decades of life. Schaltenbrand (1938) proposed three mechanisms by which spontaneous intracranial hypotension may be explained: diminished CSF production; CSF hyperabsorption, CSF leakage. The defect causing a CSF leak usually remains obscure. Several cases of diffuse meningeal enhancement on MRI have recently been described, probably due to meningeal hyperaemia resulting from the low CSF pressure. Subdural fluid collections have also been detected as a result of rupture of bridging veins due to the decrease in CSF volume and downward displacement of the brain. In our cases, MRI showed a diffuse dural thickening, hyperintense in T2. Spontaneous intracranial hypotension is often a self-limiting disease, responding well to bed rest and a generous intake of oral or parenteral fluid and salt.
