Chronic spontaneous epidural hematoma in the lumbar spine with cauda equina syndrome and severe vertebral scalloping mimicking a spinal tumor: a case report.

BACKGROUND: Chronic spinal epidural hematomas (SEHs) are rare clinical entities. SEH with vertebral scalloping is extremely rare, with only a few cases having been reported to date. We report a unique case of spontaneous chronic SEH in the lumbar spine with severe vertebral scalloping mimicking an epidural tumor. CASE PRESENTATION: A 71-year-old man presented with a 2-month history of lumbar pain and a 3-week history of paresthesia and pain in the right lower extremity, hypesthesia in the perineal and perianal regions, and bladder dysfunction. Computed tomography following myelography revealed an epidural mass lesion on the right side that compressed the dural sac and was associated with severe bony scalloping on the posterior wall of the L4 vertebral body. Magnetic resonance imaging (MRI) on T1- and T2-weighted images revealed a space-occupying lesion with heterogeneous intensity, and T1-gadolinium images showed an intralesional heterogeneous enhancement effect. A tumoral lesion in the spinal canal was suspected, based on preoperative imaging; therefore, a total spinal tumor resection was planned. Intraoperative findings revealed that the brownish lesion adhered to the dura and epidural tissues in the spinal canal, and the space-occupying mass in the scalloped cavity of the posterior wall of the L4 vertebra was encapsulated in red-brownish soft tissues. The lesion was totally resected in a piecemeal fashion, and pathological examination revealed a mixture of tissues that contained a relatively new hematoma with hemoglobin, as well as an obsolete hematoma with hemosiderin and amyloid deposits. The mass was diagnosed as a chronic epidural hematoma with recurrent hemorrhage. The postoperative course was uneventful, and the preoperative neurological symptoms immediately improved. CONCLUSIONS: The preoperative diagnosis of chronic SEHs is challenging, as MRI results may not be conclusive, particularly in patients with scalloping of bony structures. Thus, chronic SEHs should be considered as a differential diagnosis in cases of suspected tumoral lesions in the spinal canal. To the best of our knowledge, this is the first reported case of acute exacerbation of chronic SEH with cauda equina syndrome and severe vertebral scalloping.

A different aspect of the unexpected death of Mozart at the age of 35 years.

The cause of the early death of Wolfgang Amadeus Mozart (1756-1791) at the age of 35 has been the source of much discussion in the medical community. Investigators attributed to Mozart nearly 150 different medical diagnoses. However, the neurosurgical aspect of the early death of Mozart has yet to be well-analyzed, and this subject was investigated herein. The key words "Mozart" and "Mozart's death" were searched in PubMed as well as the libraries of universities. The main source was the archive and website of Internationale Stiftung MOZARTEUM/Salzburg (www.mozarteum.at) and the cranium stored in the Internationale Stiftung Mozarteum in Salzburg/Austria. The linear fracture of the cranium is important, since it shows the neurosurgical aspect of the early death of Mozart. Mozart's disease was most likely a neurotraumatologic one. His fracture likely occurred several months before his death, as evidenced by signs of healing. Intense headaches and declining musical performance in his last year may have been influenced by intracranial hemorrhage induced by the linear fracture. His final disease therefore may have been chronic postconcussion syndrome depending on chronic calcified epidural hematoma.

Ossification of Cranial Epidural Hematomas: A Systematic Review of Management Strategies and Presentation of an Illustrative Case.

The presence of a calcified or ossified chronic cranial epidural hematoma (EDH) is rare and has been described in only a few case reports in the literature. Consequently, clear treatment strategies remain elusive and may entail conservative and surgical approaches. In this study, we performed a systematic review of reported cases to evaluate the clinical course and treatment options for these patients. A comprehensive systematic search of two databases was performed, and information on patient characteristics, symptomatology, and treatment was extracted from eligible articles. A total of 56 cases were included in our analyses. Forty patients were male, 16 were female, with an average age of 21.38 years at the time of diagnosis. Assumed etiology was previous trauma in 35 cases, previous cranial surgery in 17 patients, and birth trauma and epidural bleeding after the utilization of the Mayfield clamp in 1 case each. The origin remained unclear in two cases. The time between trauma or surgery and diagnostics ranged between one and a half weeks and 50 years, with a median of 4 years (SD 9.8 years). The symptoms were very heterogeneous, ranging from acute neurological deterioration to chronic symptoms. In 15 cases, patients were asymptomatic, and cranial imaging was performed as part of a new trauma or a screening for other disease. Forty-one patients received surgical treatment by craniotomy and hematoma evacuation, and 13 patients were treated conservatively. In two cases, the liquid hematoma portion was aspirated through a burr hole. The localization of calcified or ossified EDH was mainly supratentorial. Young male patients most commonly present with calcified or ossified EDH after trauma, according to the epidemiological trend of acute EDH. Clinical presentation varies from asymptomatic to severe neurological deficits and signs of increased intracranial pressure. There is no standardized treatment; decisions must be made on an individual basis.

Chronic epidural hematoma with frontal skull-base destruction mimicking osteogenic tumor, associated with coagulopathy due to chronic hepatitis C.

Background: Intracranial epidural hematoma is generally evoked by acute coup-injury. Though rare, it has a chronic clinical course and can be a non-traumatic event. Case Description: The patient was A thirty-five-year-old man with a complaint of one-year history of hand tremor. He was suspected diagnosis of osteogenic tumor with differential diagnosis of epidural tumor, or abscess in the right frontal skull base bone, associated with chronic type C hepatitis because of his plain CT and MRI. Results: Results of examinations and surgery, the extradural mass was chronic epidural hematoma without skull fracture. We diagnosis he is the rare case of chronic epidural hematoma caused by coagulopathy due to chronic hepatitis C. Conclusion: We reported a rare case of chronic epidural hematoma caused by coagulopathy due to chronic hepatitis C. The repeated spontaneous hemorrhage in the epidural space formed the capsule and destruction of skull base bone, just mimicking skull base tumor.

The uncommon delayed neurological deficit in posterior fossa chronic epidural hematoma: A case report.

BACKGROUND: Chronic epidural hematoma (CEDH) is uncommon and therefore, less well characterized. The incidence of CEDH ranges from 3.9 % to 30 % of all epidural hematomas. Posterior fossa epidural hematomas represent a rare clinical entity. It has been reported in only 4-7 % of all extradural hematomas. This rare condition may present with rapid clinical deterioration by quick increase in size that may cause brain stem compression. This study aims to provide a case of chronic epidural hematoma with uncommon sign of delayed neurological deficits, specifically in the posterior fossa region. CASE PRESENTATION: We report a case of a 34-years-old male with left upper and lower extremities weakness for 3 days before admission. The patient had a history of falling from a height of approximately 3 m about 3 weeks ago. Craniotomy epidural hematoma evacuation was performed on the patient. CONCLUSION: Chronic epidural hematoma is uncommon and therefore, less well characterized. The results of surgical care of symptomatic chronic posterior fossa EDH are often excellent. Early diagnosis and emergent evacuation provide better outcome.

Chronic epidural hematoma presenting with diplopia.

BACKGROUND: Epidural hematomas are common intracranial pathologies secondary to traumatic brain injuries and are associated with overlying skull fractures up to 85% of the time. Although many require immediate surgical evacuation, some are observed for stability and followed up conservatively with serial imaging or enlarge slowly overtime, similar to chronic subdural hematomas. Those in the latter category may present with vague symptoms such as diplopia or headache and are often found on routine outpatient evaluation. When concerning findings such as significant mass effect are present, surgical evacuation is necessary. CASE DESCRIPTION: Here, we present the case of a 32-year-old man who presented with diplopia 6 weeks after experiencing head trauma and was found to have a chronic epidural hematoma. On resection, thick, inflammatory tissue was observed and carefully resected, revealing normal dura underneath. Six weeks after evacuation of the hematoma, the patient had near-complete resolution of his diplopia and complete resolution of his epidural hematoma. CONCLUSION: Given the consistency and nature of the fibrous material observed intraoperatively in this case, near-complete resection of the tissue was likely necessary to help facilitate adequate reexpansion of brain parenchyma and improve clinical outcomes.

Chronic Epidural Hematoma Caused by Traumatic Intracranial Pseudoaneurysm of the Middle Meningeal Artery: Review of the Literature with a Focus on this Unique Entity.

BACKGROUND: Pseudoaneurysms of the middle meningeal artery represent fewer than 1% of all intracranial aneurysms; it can be associated with different patterns of intracranial hemorrhages. A chronic epidural hematoma (CEDH) caused by post-traumatic pseudoaneurysm of the middle meningeal artery (MMA) has not yet been reported. CASE DESCRIPTION: A 17-year-old male patient was referred to our unit after a car accident, with head trauma and presented motor and language deficits. After a brain computed tomography scan that revealed a left temporal epidural hematoma, the patient underwent surgery with complete hematoma drainage and recovery. After 5 months, he developed a chronic epidural hematoma secondary to a pseudoaneurysm of the MMA, as shown by cerebral angiography. We also reviewed the literature to evaluate the state of the art concerning the diagnosis and management of patients affected by CEDH. CONCLUSIONS: Pseudoaneurysms are considered unstable because of the poor support of the aneurysmal wall. They tend to progressively increase in size and ultimately rupture, leading to delayed intracranial bleeding. A univocal definition of the interval of time between the acute head trauma and the diagnosis to classify the CEDH is still debated. To our knowledge, this is the first case described of a CEDH secondary to a pseudoaneurysm of the MMA. In our study we suggest defining CEDHs as extradural hematomas diagnosed and/or treated 21 days or more after a head injury.

Neurosurgery and Music; Effect of Wolfgang Amadeus Mozart.

BACKGROUND: The nervous system works like a great orchestra. Specifically, the music of Mozart with its "Mozart effect" is appropriate to use in neurosurgery. We investigated the relationship between Mozart's music and neurosurgery. MATERIAL AND METHODS: We used digital catalogs like "PubMed" and the libraries of universities. Key words were "Wolfgang Amadeus Mozart" and "neurosurgery and music." RESULTS: In the first half of the 20th century, performing neurosurgery on some musicians, such as Maurice Ravel, Josef Hassid, and George Gershwin, resulted in a fatal outcome. The cause of this is probably that neurosurgery had not been developed yet in the first half of the 20th century. In the past 3 decades, the neurosurgical operations of musicians show that musicians have rich associations among auditory, somatic, and sensorial systems. CONCLUSION: It is clear that we have much to learn from studies about music and brain function that derive from our surgical experiences with patients. The neuronal plasticity of musicians' brains may be different from that of nonmusicians' brains. Musicians with enhanced motor skills have greater capacity for plasticity because of enriched interhemispheric connections. Listening to music and the effect of Mozart in neurosurgical practice, intensive care, or rehabilitation were documented in many studies. As authors, we mean something different: Its effectiveness should be studied. We concluded that in current neurosurgical practice, Mozart has an effect. More research and clinical studies are needed.

Full-endoscopic interlaminar removal of chronic lumbar epidural hematoma after spinal manipulation.

BACKGROUND: Spinal manipulation is widely used for low back pain treatments. Complications associated with spinal manipulation are seen. Lumbar epidural hematoma (EDH) is one of the complications reported in the literature. If lumbar chronic EDH symptoms are present, which are similar to those of a herniated nucleus pulposus, surgery may be considered if medical treatment fails. Percutaneous endoscopic discectomy utilizing an interlaminar approach can be successfully applied to those with herniated nucleus pulposus. We use the same technique to remove the lumbar chronic EDH, which is the first documented report in the related literature. METHODS: We present a case with chronic lumbar EDH associated with spinal manipulation. Neurologic deficits were noted on physical examination. We arranged for a full-endoscopic interlaminar approach to remove the hematoma for the patient with the rigid endoscopy (Vertebris system; Richard Wolf, Knittlingen, Germany). RESULTS: After surgery, the patient's radiculopathy immediately began to disappear. Magnetic resonance imaging (MRI) follow-up 10 days after the surgery revealed no residual hematoma. No complications were noted during the outpatient department follow up. CONCLUSIONS: Lumbar EDH is a possible complication of spinal manipulation. Patient experiencing rapidly progressive neurologic deficit require early surgical evacuation, while conservative treatment may only be applied to those with mild symptoms. A percutaneous full-endoscopic interlaminar approach may be a viable alternative for the treatment of those with chronic EDH with progressive neurologic deficits.
