“…The radiological findings suggested a preoperative differential diagnosis which included cavernous malformation and myxopapillary ependymoma. After revising the literature on the association of these pathologies with SS, we have found 13 cases of cavernoma with secondary SS, none of which had a fourth ventricle location,[ 17 18 24 25 29 30 32 35 42 47 49 ] and all 8 cases secondary to myxopapillary ependymoma had an intraspinal location;[ 12 13 14 20 30 38 45 52 ] thus, it would seem that our differential diagnosis was statistically improbable. All four previously published cases of a fourth ventricular hemorrhagic mass and SS have been diagnosed as ependymoma.…”

Background:The association of a hemorrhagic tumor with secondary superficial siderosis (SS) is a relatively rare although well described phenomenon.Case Description:We present the case report of a 35-year-old male with a history of drowsiness, hypoacusia, drop attacks, and multidirectional nystagmus during the last 2 months, who presented with acute obstructive hydrocephalus caused by a fourth ventricle mass displaying radiological signs of repeated intra and extratumoral hemorrhage with SS. He underwent gross surgical removal of the solid component of the tumor. Microscopic examination revealed an ependymoma with atypical features, including prominent angiomatous formations and internal chronic hemorrhages with hemosiderin deposits, resembling a cavernoma. The scarce tumoral component, which extended around these cavernous vessels, lacked the gross typical features of fibrillary stroma or perivascular pseudorosettes.Conclusion:To our knowledge, including the present case, there are 45 published reports of tumors associating secondary SS. Besides ependymoma, no other hemorrhagic lesion, tumoral or vascular, has been previously published associating a fourth ventricle location with secondary SS. The present case represents the fifth with this finding, and we strongly suggest ependymoma as a presumptive diagnosis when this rare association is encountered. In addition, this appears to be the first case reported in the scientific literature of a hemorrhagic fourth ventricle ependymoma mimicking both, radiologically and histologically, a cavernous malformation.

“…Pneumocephalus was de ned as the presence of air in the epidural, subarachnoid, intraparenchymal, or intraventricular space (pneumoventricle) [1][2][3][4]. The pneumoventricle is mainly observed after intracranial surgery, and skull base pathology is complicated by an osteodural defect, which is particularly traumatic, or sometimes spontaneous [5,6].…”

The tension pneumoventricle is a rare subtype of pneumocephalus characterized by intracranial hypertension secondary to pathological accumulation of air in the cerebral ventricles. This rare neurosurgical emergency has a life-threatening course. A delayed posttraumatic tension pneumoventriculus is an extremely rare condition that appears 72 h after head trauma. It can occur following a skull base fracture complicated by an osteodural defect without pneumocephalus or, more rarely, as a complication of simple acute posttraumatic pneumoventricle. This pathology represents a challenge in low-income countries because of limited access to social security and brain imaging and an inefficient health transport system. Its diagnosis and treatment may require multiple brain computed tomography scans in the acute phase of trauma and rapid medical evacuation. Here we report two patients with skull base fractures whose state of consciousness deteriorated after they returned home due to delayed posttraumatic tension pneumoventricle. The patients were rapidly taken to the hospital and treated in the emergency department, and their outcome was generally favorable. These cases underline the importance of regular, high-quality follow-up for skull base trauma patients in low-income countries, even after discharge from the hospital.

Superficial siderosis of the central nervous system: secondary progression despite successful surgical treatment, mimicking amyotrophic lateral sclerosis. Case report and review

2010

View full text Add to dashboard Cite

Superficial siderosis of the central nervous system is a rare disorder with hemosiderin deposition in the spinal and cranial leptomeninges and subpial layer, mostly from repetitive subarachnoid hemorrhage. Progressive sensorineural deafness, cerebellar ataxia, and pyramidal signs comprise the typical clinical presentation. We describe a 47-year-old patient, who showed initial 2-year improvement after successful occlusion of an intradural bleeding source at T4. Secondary progression of symptoms without further bleedings was noted thereafter, with a clinical picture of amyotrophic lateral sclerosis. This case illustrates that the disease may progress secondarily even without re-bleedings, and that secondary progression might be due to a similar pathomechanism as in amyotrophic lateral sclerosis.
