Alexia without Agraphia in a Musician after Transcallosal Removal of a Left Intraventricular Meningioma

Abstract After a meningioma situated in the trigone of the left lateral ventricle was excised by the transcallosal approach of Kempe and Blaylock, a right-handed musician with a right hemianopsia developed alexia without agraphia. In contrast to previously reported cases of this syndrome arising from other etiologies, he was unable to read single letters or numbers. Neuropsychological studies at 42 and 126 days after operation also disclosed an inability to associate auditory or tactile stimuli with visually perceived material, whereas speech and verbal comprehension were intact. Although the alexia extended to musical notes, he could interpret other musical symbols (e.g., treble clef). Appreciation of rhythm and expressive musical ability were relatively preserved, although judgment of other musical features (including discrimination of pitch, duration, and loudness) was compromised. The findings suggest that alexia may occur as a consequence of the transcallosal procedure when a right hemianopsia is present. However, other linguistic abilities may be better preserved by the transcallosal approach to the ventricle than by a transcortical operation.

Background:Metastatic renal cell carcinoma to the choroid plexus is a rare condition and can be easily confused with meningioma.Methods:A 61-year-old female presented with progressive neurologic deterioration and MRI findings of obstructive hydrocephalus and a homogeneously contrast enhancing 3 cm oval mass in the trigone of the left lateral ventricle.Results:Despite radiologic, intraoperative gross features, and frozen pathology all consistent with meningioma, the final pathology revealed metastatic renal cell carcinoma.Conclusion:Renal cell carcinoma metastatic to the choroid plexus can mimic intraventricular meningioma. We present a review of the literature and comparison of the radiological features of meningiomas and metastatic renal cell carcinoma. We also discuss the use of an under-utilized technique, the contralateral transcallosal approach, in the surgical treatment of this intraventricular lesion.

The aim in reporting this case was to discuss the pathophysiology and treatment issues in an infant with a giant syringobulbia associated with a right cerebellopontine angle (CPA) arachnoid cyst causing noncommunicating hydrocephalus. This 7-month-old infant presented to the hospital with a history of delayed milestones and an abnormal increase in head circumference. Magnetic resonance images and CT scans of the brain showed a large CSF cavity involving the entire brainstem and a right CPA arachnoid cyst causing obstruction of the fourth ventricle and dilation of the lateral and third ventricles. Cerebrospinal fluid diversion was performed by direct communication from the syringobulbia cavity to the left lateral ventricle and from the left lateral ventricle through another ventricular catheter; external ventricular drainage was performed temporarily for 5 days. Communication between the syrinx and arachnoid cyst was confirmed. Clinically, there was a reduction in head circumference, and serial MR imaging of the brain showed a decrease in the size of the syrinx cavity and the ventricle along with opening of the normal CSF pathways. The postoperative course was uneventful, and no further intervention was necessary. On follow-up of the child at 3 years, his developmental milestones were normal. Surgical intervention for this condition is mandatory. The appropriate type of surgery should be performed on the basis of the pathophysiology of the developing syringobulbia.

✓The authors report a case of inflammatory pseudotumor that developed in the choroid plexus of the lateral ventricle. The patient was a 73-year-old man who had undergone surgery for rectal cancer at another hospital 5 years earlier. He was referred to the authors' department, with his chief symptoms consisting of disorientation, right hemiparesis, and gait disorder that had gradually developed during the preceding month. On computed tomography and magnetic resonance imaging, a well-demarcated and homogeneously contrasted tumorous lesion was noted in the region from the trigone to the medial wall of the inferior horn of the left lateral ventricle. Expansion of the inferior horn was also evident. Intraoperative findings showed that the tumor originated from the choroid plexus of the lateral ventricle, and the histopathological diagnosis was inflammatory pseudotumor. There are only 4 previously reported cases of inflammatory pseudotumor that developed in the choroid plexus; the authors review the literature and discuss the clinicopathological characteristics of the condition.

Abstract BACKGROUND Intracranial dermoid cysts (DC) are rare congenital non-neoplastic lesions that account for 0.04 – 0.6% of all intracranial tumors. They are formed by a fibrous capsule composed of epidermal and dermal derivatives (hair follicles, sebaceous and sweat glands), enclosing a viscous fluid. Intradural DC often arise in the midline and are more common in infratentorial locations. CASE REPORT: A 14-year-old male patient presented with headache, partial motor seizures and behavioral changes. Neurological examination and endocrine workup revealed no abnormalities. Brain magnetic resonance imaging showed a lesion that was 4.4cm x 2.2cm x 4.4cm in size, located at supraselar region, and extended superiorly to the left lateral ventricle and anterolaterally to the left orbitofrontal lobe, associated with hyperintense fat droplets in the right lateral ventricle. We performed a left transventricular microsurgical approach. The tumor capsule was coagulated and opened and a subtotal resection with peacemeal removal of the the lesion was obtained: it had gelatinous consistency, composed of droplets of fat and hair and keratinized scamous epihelium content. A total removal of the DC capsule was not possible due to its firm adherence to optic chiasm and to hypothalamus. Histological examination revealed dermoid cyst. CONCLUSION Surgery is the only effective treatment, and its goal should be the radical resection of the lesion to avoid recurrence. Whenever radical resection is not possible, because of the adhesions of the cyst capsule to surrounding tissues, a subtotal resection with piecemeal removal may be a satisfactory option in such cases to avoid high morbidity.

✓ Except for villous hypertrophy of the choroid plexus that may not be true tumors, multiple choroid plexus papillomas are extremely rare. The authors report a case involving multiple choroid plexus papillomas that were distinct from villous hypertrophy. These lesions were localized, one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. A review of the literature revealed that this case represented the first reported case of true multiple choroid plexus papillomas documented by findings on magnetic resonance imaging.

Abstract Introduction: Tumors of the lateral ventricle are rare lesions including a large variety of benign or malignant tumors. These tumors could originate in the ventricular wall or arising and expanding within the lateral ventricle from the surrounding neural structures. The purpose of this study is to discuss postoperative results and factors that affected the preference for transcallosal or transcortical approach. Material and methods : We performed a retrospective study, lasted between 2005- 2013, that comprised 26 consecutive patients who underwent operation for lateral ventricle tumors. The main clinical symptoms and signs were associated with the localization and size of the tumors. Cerebral computed tomography and magnetic resonance imaging were used to determine the location and expansion of each tumor. The transcortical approach was used in 17 patients and the transcallosal approach was used in 9 patients. Results : Total tumor resection was achieved in 73% of cases (19 patients). Most frequent histological tumor’s type was glioblastoma, choroid plexus papilloma, ependymoma and meningioma. Signs of increased intracranial pressure were most dominant. One patient died because of postoperative intraventricular hemorrhage. Additional neurological deficits were seen in 3 patients and postoperative seizure occurred in three patients. One patient with preoperative hydrocephalus required ventriculoperitoneal shunting after tumor’s resection. Two patients developed postoperative epidural hematoma and one required reoperation. 15 of 26 patients received postoperative radiotherapy and 6 of them received adjuvant chemotherapy. The mean duration of postoperative evaluation was 24,32 (range 5-92). Excepting the cases with subtotal resection, two patients were reoperated for recurrences. Conclusions : The nature, size, location and vascularization of intraventricular tumors are the most important elements influencing the choice of surgical approach. Surgeons must evaluate all these factors and prefer the short and safe way to remove the tumor.
