Meckel's cave.

OBJECTIVE: To review the microsurgical anatomy of Meckel's cave, a detailed knowledge of which is a prerequisite to devising an appropriate surgical strategy and performing successful surgery. METHODS: The microsurgical anatomy of Meckel's cave was studied under an operating microscope in 15 human cadaver heads (30 sides). To understand the meningeal architecture and the cross-sectional anatomy of Meckel's cave, serial histologic sections were made in an additional adult human cadaver specimen. RESULTS: Meckel's cave is a natural mouth-shaped aperture connecting with the posterior fossa that is located in the medial portion of the middle cranial fossa. The cave extends forward similar to an open-ended three-fingered glove and provides a channel for the rootlets of the trigeminal nerve; the trigeminal ganglion; and the ophthalmic (cranial nerve V(1)), maxillary (cranial nerve V(2)), and mandibular (cranial nerve V(3)) divisions until they reach their respective foramina. The average height of this oval mouth was found to be 4.2 mm (range 3-5 mm) and the average width was 7.6 mm (range 6-8 mm). The mouth of Meckel's cave was located 12 mm (range 10-15 mm) superior and medial to the internal acoustic meatus and 6.5 mm (range 5-8 mm) superior and medial to the dural point of entrance of the nervus abducens and 20 mm (range 18-23 mm) medial to the arcuate eminence. CONCLUSIONS: Detailed and sound knowledge of the microsurgical anatomy of Meckel's cave, which borders on surgically important structures, such as the internal carotid artery and cavernous sinus, is essential to performing precise microneurosurgery in this region. This study describes the complex anatomy of Meckel's cave and surrounding structures to provide the knowledge needed to devise a more complete surgical strategy and establish accurate orientation during the surgical procedure.

Effects of prone and jackknife positioning on lumbar disc herniation surgery.

BACKGROUND: Intra-abdominal hypertension due to surgical position increases bleeding at the surgical site. In this study, we evaluated the impact of prone and jackknife position on intra-abdominal pressure (IAP), lung mechanics, blood loss at the surgical site, and duration of the surgical procedure on lumbar disc operations. METHODS: Forty patients operated for single-space lumber disc herniation were included in our study. All patients were ASA I-II and 18 to 70 years old. Patients who had undergone previous spinal surgery, were on anticoagulant or anti-aggregant therapy, had hypertension, cardiac, respiratory, liver, or renal disorders, and were obese (Body Mass Index >35 kg/m²) were excluded. Patients were randomly assigned to either the prone or the jackknife position for surgery. Differences in lung mechanics, IAP, and surgical-site blood loss were calculated in both patient groups. Changes in pulmonary and abdominal pressure levels were measured both in face-up and down positions. RESULTS: Bleeding at the surgical site (prone: 180.0±100.0 mL, jackknife: 100.0±63.6 mL, P=0.018) and IAP (prone: 11.0±3.0 mm Hg, jackknife: 8.0±2.0 mm Hg, P=0.006) were significantly reduced when patients were in the jackknife position. Operating time was approximately 40 minutes shorter in the jackknife position group, although this difference was not significant. CONCLUSIONS: The jackknife position causes less IAP elevation and less surgical site bleeding compared with the prone position. The jackknife position is the preferred choice for single-level lumbar disc surgery in healthy, nonobese patients.

The effects of protein kinase C activator phorbol dibutyrate on traumatic brain edema and aquaporin-4 expression.

BACKGROUND: Aquaporin-4 (AQP4) is the major water channel in the central nervous system. Brain edema emerges from increased AQP4 expression in traumatic brain injury (TBI). Cell line studies have shown that the protein kinase activator phorbol ester exerts a suppressive effect on AQP4 and water permeability. The aim of this study was to investigate the effects of a phorbol ester, phorbol dibutyrate (PDBu), on increased TBI AQP4 expression and accompanying brain edema. METHODS: Fifty-six male Wistar rats were first divided into two groups: the edema group, in which the percentage of water in brain tissue would be evaluated, and the immunohistochemical group, allowing AQP4 expression to be determined. Both groups were further sub-divided into four groups consisting of 7 subjects. These four groups were as follows: sham-operated control group, severe diffuse TBI group, 0.9% saline-treated diffuse TBI group, and the PDBu-treated diffuse TBI group (2300 µg/kg, iv). The results were evaluated statistically. RESULTS: PDBu treatment significantly reduced brain water concentration (p<0.001). Furthermore, PDBu was found to reduce trauma-induced AQP4 upregulation (p<0.05). CONCLUSION: This study showed that traumatic brain edema was prevented by intravenous PDBu administration via AQP4 downregulation, supporting the idea emphasizing the importance of AQP4 expression control in TBI.

Analyses of clinical prognostic factors in operated traumatic acute subdural hematomas.

BACKGROUND: Traumatic acute subdural hematoma is the most lethal of all head injuries. METHODS: In this study, 113 patients with the diagnosis of posttraumatic acute subdural hematoma, who were operated between 1998 and 2006, were reviewed retrospectively. Statistical analysis was performed to detect any effects of the variables of age, Glasgow Coma Scale (GCS) score on admission, time interval between the trauma and operation, and abnormality in the pupil reaction on the disease mortality and morbidity. RESULTS: Results obtained in the study are discussed and compared with the related current literature. The overall mortality in 113 patients was 56.6%. CONCLUSION: According to the results, the most important determinants of the prognosis are GCS score of the patient on admission, abnormality in pupil reaction, timing of the operation, and the patient's age.

The effects of tibolone on the human primary glioblastoma multiforme cell culture and the rat C6 glioma model.

OBJECTIVES: In the light of recent advances in tumor biology and genetics, we hypothesized that tibolone, an estrogen receptor agonist, may have antiproliferative effects on primary human glioblastoma cells and rat C6 malignant glioma cell lines. We thought that tibolone should exert its antiproliferative effects by augmenting glial cell differentiation through the naive, nonhypermethylated estrogen receptors in the glioma cells. METHODS: Human primary glioblastoma multiforme (GBM) cells were acquired perioperatively from ten patients aged between 45 and 69 years, diagnosed clinically and radiologically with GBM. The diagnosis was confirmed using immunohistochemical assays. Human GBM and rat C6 malignant glioma cells were cultivated in vitro to obtain monolayer cell cultures. Tibolone was then applied to these cultures in wells, each containing 500,000 tumor cells. RESULTS: Tibolone significantly decreased the number of human GBM cells at the concentrations of 10 and 100 mg/ml. For tibolone, a strong dose-dependent correlation in tumor inhibition was found (p=0.001). This antiproliferative effect of tibolone in human GBM cells was not observed in rat C6 malignant glioma cells. Tibolone demonstrated differential effects on human GBM and rat C6 glioma cells. DISCUSSION: In vitro antiproliferative effects of tibolone on human GBM need to be investigated further in in vivo works.

[Epidemiological study in head injury patients]. / Kafa travmali hastalarda epidemiyolojik çalisma.

BACKGROUND: The aim of this study was to determine the hospital-based epidemiological data of the head injury patients who admitted to our Emergency Surgery Department. METHODS: The records of the patients (284 males [66%], 146 females [34%]; mean age 30+/-19) with head injury who admitted to our Emergency Surgery Department between 01.01.2006 - 31.12.2006 were analyzed retrospectively. RESULTS: Among the age groups, most head injuries occurred in children (22%) and young adults (30%). The most common trauma types were due to falls (40%) and motor vehicle accidents (37%). The mortality rate in head injury patients was 11%, serious morbidity was 2%, and the rate of deaths from head injury among all deaths in 2006 was 30%. CONCLUSION: According to these data, the most common causes of death in head-injured patients are falls (0-16 years of age) and outside vehicle traffic accidents and cranial gunshot wounds (16-35 years of age), especially for males. Admission Glasgow Coma Score is an important prognostic factor in head-injured patients. Primary precautions for head injury must be taken according to each age group. Further development of the diagnosis and treatment options will help to lower the mortality and morbidity of patients with traumatic brain injury.

Carotid endarterectomy with regional anesthesia: an audit of 71 cases.

AIM: The aim of carotid endarterectomy (CEA) is the successful removal of the atherosclerotic plaque and meticulous anatomical and physiological reconstruction of the carotid artery without any perioperative complications. Endarterectomy can also be carried out with regional anesthesia, which allows monitoring of the neurological status. This study reviews patients who underwent CEA with regional anesthesia. MATERIAL AND METHODS: A total of 71 consecutive patients were planned to undergo carotid endarterectomy under regional anesthesia between 2000 and 2006. All of these patients, assessed by our neurovascular team, were recruited prospectively and the data was analyzed retrospectively. RESULTS: The study group consisted of 23 women and 48 men with a mean age of 62 (range 37-79). 67 patients (94,4%) had symptomatic, and 4 (5,6%) had asymptomatic (5.6%) carotid stenosis. Six patients (8.45%) were intolerant to carotid clamping (8,45%). The stroke morbidity rate was 1.4% and the mortality rate was 1.4%. The mean hospitalization time was 2.07 (range 1-10) days. CONCLUSION: Carotid endarterectomy performed under regional anesthesia can be a safe method which may lead to better neurological outcome. This method offers several advantages including monitorization of the cerebral ischemia during surgery, usage of selective shunting, decreased need for intensive care and shorter hospitalization time.

Effect of magnesium, MK-801 and combination of magnesium and MK-801 on blood-brain barrier permeability and brain edema after experimental traumatic diffuse brain injury.

OBJECTIVE: Glutamate antagonists are very attractive drugs in laboratory works to protect neural tissue against ischemia. In this work, the effects of magnesium, MK-801 and combination of magnesium and MK-801 on blood-brain barrier (BBB) and brain edema after experimentally induced traumatic brain injury are evaluated. METHODS: A standard closed head injury was induced on the rats by a controlled impact device using a 450-g free falling mass from a height of 2 m onto a metallic disc fixed to the intact skull. One of the following was injected to animals intraperitoneally 30 minutes after injury: saline, magnesium, MK-801 and magnesium plus MK-801. To quantify the brain edema, the specific gravity of the brain tissue was determined. To demonstrate the alteration of the BBB permeability, Evans blue dye was used as a tracer. RESULTS: In all treatment groups, the specific gravity of brain tissue values was significantly higher compared with the control group. Evans blue dye content in the brain tissue was significantly reduced in all three treatment groups with respect to the control group. There was no significant difference of effect between the groups of magnesium alone and MK-801 alone when compared with each other and when compared with their combination. CONCLUSION: The present data demonstrate that treatment with magnesium, MK-801 and combination of magnesium and MK-801 can reduce formation of brain edema and can help restore BBB permeability after experimental diffuse brain injury.

The microsurgical anatomy of the hypoglossal canal.

BACKGROUND: The hypoglossal canal (HC) is a region of the skull base whose involvement in many pathological entities is often ignored. Adequate knowledge of the anatomy of the HC and its related bony, neural, and vascular structures is essential for surgery of lesions involving this area. METHODS: Ten adult human cadaver heads from a US source fixed by formalin (20 sides) and 20 dry human skulls from Indian sources (40 sides) were used in this study. Various aspects of the anatomy of this region including the size, course and variation of the hypoglossal nerve and its relationship to the adjacent and canalicular course were recorded. RESULTS: The left HC was located at 10 o'clock and the right HC at the 2 o'clock position with respect to the foramen magnum. The canal was surrounded superiorly by the jugular tubercle, superolaterally by the jugular foramen, laterally by the sigmoid sinus and inferiorly by the occipital condyle. All dry skulls were drilled in the horizontal plane at an axis of about 45 degrees and directed slightly upwards. CONCLUSIONS: Detailed knowledge of the microsurgical anatomy of the region of the HC is crucial when performing surgery for lesions of the condylar region, the lower clivus, and ventral brain stem. This study provides the knowledge required to achieve accurate orientation and effective maneuvers during surgical procedures for treatment of the patient without injuring the vital neural and bony structures.

The first Anatolian contribution to treatment of sciatica by Serefeddin Sabuncuoglu in the 15th century.

Serefeddin Sabuncuoglu was an early 15th century surgeon in Anatolia. His masterpiece entitled Cerrahiyetül Haniye (Imperial Surgery) is the first illustrated surgical textbook in the Turkish Islamic literature of the Ottoman era Anatolia. It is the first written medical-surgical work in Anatolian history and it covers the treatment of more than 40 illnesses, which range from hydrocephalus to sciatica. This study aims to investigate the contribution of Anatolia to neurosurgery through Sabuncuoglu's treatment of sciatica, a problematic and common illness.

Effects of arterial and venous wall homogenates, arterial and venous blood, and different combinations to the cerebral vasospasm in an experimental model.

BACKGROUND: Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality and morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations differ from each other. This variability has not been completely explained by blood and blood degradation products. Therefore, metabolites released from the damaged vessel wall during the bleeding are thought to play an important role in vasospasm. METHOD: To test this hypothesis, we used 46 male Wistar rats that were divided into 7 groups and administered one of the following to cisterna magna: venous blood, arterial blood, arterial wall homogenate, venous wall homogenate, combined mixture of arterial blood and artery wall homogenate, or combined mixture of venous blood and venous wall homogenate. Brainstems of the rats were excised, and the basilar arteries were harvested for morphometric measurements. RESULT: There were significant differences between the degree of vasospasm caused by arterial and venous blood (P < .0001). The intraluminal area of the basilar artery was significantly narrower after application of arterial blood, artery wall homogenate, or their combination (49% +/- 1%) than after venous groups (30% +/- 1.9%) (P < .0001). CONCLUSION: The results of this experiment demonstrated that metabolites from vessel walls play as important roles in the pathophysiology of vasospasm as blood and blood degradation products. Further investigation of these metabolites will improve our understanding of vasospasm, pathophysiology, and its treatment.

Microvascular decompression as a surgical management for trigeminal neuralgia: long-term follow-up and review of the literature.

This retrospective study summarizes our experience based on treating 62 patients with trigeminal neuralgia treated with microvascular decompression. All patients had typical trigeminal neuralgia symptoms, with 24 of them (38%) having failed to benefit from other previous treatment paradigms. We excluded subjects with atypical and/or secondary forms of trigeminal neuralgia. Follow-up duration ranged from 5 months to 10 years 6 months, with recurrence being identified in three patients (4.8%).We found that the superior cerebellar artery is the leading offending vessel in our cases (33.9%; 21 patients). Interestingly, seven patients (11.3%) underwent an early reoperation 12-48 h later after the first operation was deemed ineffective. This subgroup recovered satisfactorily following isolation of the pathogenic vessels. Overall, no mortality was observed in our patients, and the only permanent morbidity outcome was a case of facial nerve palsy (1.6%). We conclude that microvascular decompression and its reapplicaiton for patients who showed no pain relief immediately after the first decompression are safe and effective treatments for trigeminal neuralgia.

Surgical outcome in hippocampal sclerosis following selective amygdalo-hippocampectomy.

OBJECTIVES: Temporal lobe epilepsy is the most common form of intractable partial epilepsy in adults with hippocampal sclerosis accounting for the majority of cases. Selective amygdalo-hippocampectomy (SEAH) is suggested as a safe and effective surgical procedure with the advantage of a better cognitive outcome. METHODS: We prospectively documented 56 consecutive patients with medically refractory medial temporal lob epilepsy. Candidates for surgery were determined as those with characteristic clinical and imaging findings, ictal recordings, and neuropsychological evaluation. A standard SEAH was performed and hippocampal sclerosis was histologically confirmed. RESULTS: In our study 76.7% of patients were classified as Engel I and 62.2% as ILAE I at their last follow up. Overall, at the last follow-up, 51.8% of patients were seizure-free since surgery (Engel 1a and ILAE 1a), 25% had stopped antiepileptic treatment, and another 52% had decreased either the dosage or number of antiepileptic drugs. 86.3% of the patients with abnormality on neurocognitive tasks showed improvement at the end of the 6 months post surgery. CONCLUSION: SEAH is a safe and effective surgical procedure without the necessity of a larger resection and further invasive methods.

Surgical anatomy of the cervical sympathetic trunk during anterolateral approach to cervical spine.

The sympathetic trunk is sometimes damaged during the anterior and anterolateral approach to the cervical spine, resulting in Horner's syndrome. No quantitative regional anatomy in fresh human cadavers describing the course and location of the cervical sympathetic trunk (CST) and its relation to the longus colli muscle (LCM) is available in the literature. The aims of this study are to clearly delineate the surgical anatomy and the anatomical variations of CST with respect to the structures around it and to develop a safer surgical method that will diminish the potential risk of CST injury. In this study, 30 cadavers from the Department of Forensic Medicine were dissected to observe the surgical anatomy of the CST. The cadavers used in this study were fresh cadavers chosen at 12-24 h postmortem. The levels of superior and intermediate ganglions of cervical sympathetic chain were determined. The distance of the sympathetic trunk from the medial border of LCM at C6, the diameter of the CST at C6 and the length and width of the superior and intermediate (middle) cervical ganglion were measured. Cervical sympathetic chain is located posteromedial to carotid sheath and just anterior to the longus muscles. It extends longitudinally from the longus capitis to the longus colli over the muscles and under the prevertebral fascia. The average distance between the CST and medial border of the LCM at C6 is 11.6 +/- 1.6 mm. The average diameter of the CST at C6 is 3.3 +/- 0.6 mm. Superior ganglion of CSC in all dissections was located at the level of C4 vertebra. The length and width of the superior cervical ganglion were 12.5 +/- 1.5 and 5.3 +/- 0.6 mm, respectively. The location of the intermediate (middle) ganglion of CST showed some variations. The length and width of the middle cervical ganglion were 10.5 +/- 1.3 and 6.3 +/- 0.6 mm, respectively. The CST's are at high risk when the LC muscle is cut transversely, or when dissection of the prevertebral fascia is performed. Awareness of the CST's regional anatomy may help the surgeon to identify and preserve it during anterior cervical surgeries.

Ictal singing due to left mesial temporal sclerosis.

Simple ictal or interictal automatisms are commonly seen in epilepsy, whereas complex automatisms are rare. Simple ictal vocalizations or appendicular automatisms have been reported to be due to mesial temporal lobe epilepsy. However, seizure-associated singing and dancing is very rare. We report a seventeen-year-old patient with ictal singing and rhythmic swinging of the arms as a dancing gesture. The video-EEG recording showed ictal left temporal lateralization and neuropathology confirmed left mesial temporal sclerosis.

Localization of cerebrospinal fluid leaks by gadolinium-enhanced magnetic resonance cisternography: a 5-year single-center experience.

OBJECTIVE: Intrathecal gadolinium (Gd)-enhanced magnetic resonance (MR) cisternography is a newly introduced imaging method. Two main objectives of this study were to investigate the sensitivity of Gd-enhanced MR cisternography for presurgical localization of cerebrospinal fluid (CSF) leaks in patients with CSF rhinorrhea and to study the potential long-term adverse effects of intrathecal Gd application. METHODS: Fifty-one patients (19 women; mean age, 36.2 yr) with CSF rhinorrhea were included in the study. A total of 0.5 ml of Gd was injected into the lumbar subarachnoid space. T1-weighted MR cisternographic images were obtained to detect CSF leakage. The patient's neurological states and vital signs were recorded for the first 24 hours after the procedure. Neurological evaluations were repeated 1, 3, and 12 months after the procedure. The patients were followed for at least 3 years with annual neurological examinations. RESULTS: Gd-enhanced MR cisternography demonstrated CSF leaks in 43 of the 51 patients. The sensitivity of Gd-enhanced MR cisternography for localization of CSF leaks was 84%. Forty-four patients underwent surgery to repair dural tears. Surgical findings confirmed the results of Gd-enhanced cisternography in 43 of the 44 patients who underwent surgery (98%). Eight patients with negative Gd-enhanced MR cisternography had no active rhinorrhea at the time of procedure, and seven of them did not need surgery. None of the patients developed an acute adverse reaction that could be attributed to the procedure. None of the patients developed any neurological symptoms or signs caused by intrathecal Gd injection during a mean follow-up period of 4.12 years. CONCLUSION: Gd-enhanced MR cisternography is a sensitive and safe imaging method for detection of CSF leaks in patients with rhinorrhea.

Traumatic epidural hematomas of the posterior cranial fossa.

BACKGROUND: Traumatic EDHs of the posterior cranial fossa are rare and have a higher mortality than supratentorial localizations. Early diagnosis of TEHPCF and prompt surgical evacuation provide excellent recovery. Active use of cranial CT scanning has taken a major role in the diagnosis, surgical indication, close observation, and strategy planning. As a result, better prognosis is achieved. In this study, we represent our results and experiences in the management of TEHPCF. METHODS: Between 1993 and 2006, 65 patients with TEHPCF were treated in Istanbul University Faculty Of Medicine, Neurosurgery and Emergency Surgery Departments. The hospital records of these patients were analyzed retrospectively. RESULTS: Of 65 patients, whose diagnosis and management decisions were determined by cranial CT scans, 53 were treated through surgery and 12 by conservative methods. Of the 53 surgically treated patients, 2 (3%) patients died, and 2 (3%) other patients remained moderately disabled during their discharge. As a result, 61 (94%) of 65 patients had excellent recovery. CONCLUSION: When compared with the literature, our mortality rate was superior to other previously reported studies. In our opinion, this is a result of extensive use of the cranial CT scan together with aggressive surgery. Patients with occipital trauma should be evaluated using cranial CT scans, and those showing mass effect should be immediately treated surgically. The patients that have no mass effect on CT scans can be closely observed by planned serial control CT scans.

[Craniocerebral civilian gunshot wounds: one hospital's experience]. / Kranyoserebral atesli silah yaralanmalari: bir hastanenin deneyimi.

BACKGROUND: In this study we have discussed the factors that affect our surgical results according to our experience on patients who were admitted to our hospital's Emergency Surgery Department for civilian craniocerebral gunshot wounds between 1997 and 2006. METHODS: The clinical and radiological findings of 82 patients (74 males, 8 females) who were treated for civilian craniocerebral gunshot wounds were retrospectively recorded. Neurological and physical examination, cranial computerized tomography (CCT) findings, trauma types, treatment modalities, prognosis, complications, morbidity and mortality rates were analyzed. RESULTS: Seventy-four (90%) of the patients were male, the mean age was 29.2 year. The Glasgow Coma Scores (GCS) during admission were as following respectively: 3-5 in 35 patients, 6-8 in 9 patients, 9-12 in 19 patients and 13-15 in 19 patients. According to their radiological findings, most commonly subdural hematoma, intracerebral hematoma, multiple contusion, depressed fracture and subarachnoidal hematoma were encountered. Operation or debridement was performed in 51 patients totally. Forty-one patients died and the mortality rate of 82 patients was calculated as 50%. CONCLUSION: The mortality rate of craniocerebral gunshot wound is high. The patients with GCS higher than 8 and with unihemispheric lesions during admission have better prognosis. We concluded that all patients must undergo debridement and the patients that have mass effect must be operated as soon as possible.

Spinal cavernous malformations: a report of 5 cases.

BACKGROUND: This is a report of 5 patients treated surgically for SCMs. METHODS: During the period from 1998 to 2003, 5 patients (4 male and 1 female) harboring SCMs were treated surgically (all of them underwent complete surgical removal). Patients' ages ranged between 22 and 57 years (mean age, 46 years). Median duration of symptoms was 31 months (1-120 months). Diagnosis was made by MRI scan showing lesions in length of 1 to 6 cm in diameter (mean length, 2.9 cm). Three lesions were found in the cervical, one in the upper dorsal, and one in the lower dorsal cord. One of them was located extradurally, one of them intradural extramedullary, and 3 of them intramedullary. RESULTS: An MRI examination showing total removal was performed postoperatively in each patient (the postoperative MRI examinations revealed total removal in all cases). The follow-up period ranged from 1 to 4 years (mean, 27 months). All patients showed clinical improvement, with 3 of them worsening early in the postoperative period but doing better in long-term follow-up (although 3 of 5 patients had worse neurological examinations in the early postoperative period, all recovered in long-term follow-up and clinically improved relative to preoperative status). CONCLUSION: Neurological status of the patients can worsen in the early postoperative period, causing intramedullary operation; but it usually improves relative to preoperative status. Surgical removal seems to be a safe and a promising way of treatment of symptomatic SCMs.

Sporadic multiple cerebral cavernomatosis: report of a case and review of literature.

OBJECTIVE: Cerebral cavernous malformations (CCM) are vascular malformations causing seizures and cerebral hemorrhages. They occur in sporadic and familial forms. Familial cases are associated with a high frequency of multiple lesions, which are less frequently associated with sporadic cases. CASE REPORT: We report a 46-year-old woman presenting with epilepsy with multiple cerebral cavernomatosis on MRI. Because she had had a previous liver transplantation operation, and received immunosuppressants, she was not advised to have a brain operation. However, she had to be operated as a result of a bleeding in one of her cerebral cavernomas. The histologic diagnosis was cavernoma. She has been seizure free after the operation with levetiracetam therapy for the last 17 months. She had no positive family history for both epilepsy and cavernomatosis. CONCLUSION: When multiple cerebral cavernomatosis are identified in a patient, a detailed neurologic family history should be sought despite the possibility of its being a sporadic case. Our main intention is to present a patient who is surgically controversial and to point out the importance of genetic heredity.
