Intramedullary sclerosing meningioma: operative video

Giada Garufi, Giuseppe Ricciardo, Alfredo Conti, and Salvatore Massimiliano Cardali

Transcript We present here a case of a 66-year-old woman who was admitted to our institution with a 6-month history of progressive extremities weakness, paresthesias of both superior arms, worse on the right side, followed by gait and balance disorders. She has a history of meningiomatosis where a huge convexity meningioma was operated 5 years early without any neurological impairment. At the neurological examination, the patient exhibited a decreased general muscle strength with a 3/5 MRC scale quadriparesis, a bilateral C4–5 territory

Intracanalicular meningioma with normal tomography

Case report

John O. Susac, Albert N. Martins, and Robert A. Whaley

A ccording to “Walsh's Dictum” progressive loss of vision in one eye is due to a compressive lesion of the optic nerve. In a classic paper on this subject, Little, et al. , 2 recommended surgical exploration despite negative neuroradiological procedures. More recently Knight, et al. , 1 stated that with the use of polytomography of the sella and canals, pneumotomography, and selective angiography with magnification and subtraction, even the smallest prechiasmal tumors could be detected. The patient reported here had a meningioma that involved the

Androgen receptor expression in meningiomas

Rona S. Carroll, Jianping Zhang, Kathleen Dashner, Madhabananda Sar, Elizabeth M. Wilson, and Peter McL. Black

T he incidence of meningioma is twice as high in females as in males. 8, 52 In women the growth of meningiomas appears to be accelerated during the luteal phase of the menstrual cycle and during pregnancy. 3, 51 There is also an association between meningioma and breast cancer: three separate studies have demonstrated a positive correlation between these two entities. 18, 44, 55 These observations suggested that meningiomas are a target for gonadal steroids. Numerous studies have been performed that examined the role of steroid receptors in meningioma

Primary optic nerve sheath meningiomas

Report of nine cases

W. Craig Clark, Charles S. Theofilos, and James C. Fleming

P rimary optic nerve sheath meningiomas are generally regarded as rare tumors. There has been some degree of confusion regarding the incidence of these tumors because of their infrequent occurrence, the difficulty in determining the actual site of origin in large tumors, 1, 16 and the confusion between meningiomas and the arachnoid hyperplasia that often accompanies optic gliomas. 2 In Cushing's series of 313 meningiomas, 4 there was only one which arose from the sheath of the optic nerve. Other series of both meningiomas and orbital tumors support this

Recurrent spheno-orbital meningioma

Joseph C. Maroon, John S. Kennerdell, Danko V. Vidovich, Adnan Abla, and Linda Sternau

T he vagaries of diagnosis and treatment of spheno-orbital meningiomas have taxed the ingenuity and surgical expertise of the most skilled neurosurgeons including Cushing, 15 Olivecrona, 40 MacCarty, 32 Guiot, Derome, and colleagues, 16, 17, 23, 24 Basso, et al. , 9 Castellano, et al. , 12 Stern, 46 Dolenc, 18, 19 Jane and colleagues, 27, 28 Al-Mefty and colleagues, 2–7 and others. Their observations and contributions, however, are sometimes overlooked by neurosurgeons and ophthalmologists confronted by these unusual tumors, which are located in

Subdural meningioma of spinal cord

Case Report

David A. Carter, David W. Rowed, and Anthony J. Lewis

E xtensive longitudinal involvement of the spinal subdural space by a tumor without diffuse meningeal origin is unusual. We report a case of meningioma growing in this fashion and suggest methods of radiological recognition of this pattern of tumor growth. Case Report This 23-year-old man was initially examined in the summer of 1983, when he complained of progressive right arm weakness. He had been well until 1977, when he noted episodic bilateral visual blurring. A diagnosis of optic glioma involving the chiasm and both optic nerves was made after

Chordoid meningioma in a child

Case report

Hitoshi Kobata, Akinori Kondo, Koichi Iwasaki, Hirofumi Kusaka, Hidefumi Ito, and Shinji Sawada

U nusual variants of meningioma containing abundant lymphoplasmacellular infiltrates are reported to be frequently associated with hematological abnormalities. The most recent World Health Organization 15 classification includes two subtypes of this entity: lymphoplasmacyte-rich (LPR) and chordoid meningioma. Both are rare variants, and the latter in particular is characterized by its resemblance to chordoma. However, the clinical and pathological features of these tumors are not well characterized because few case reports are available. To the best of our

Meningioma of the anterior part of the third ventricle

Case report

Thomas M. Markwalder, Regula V. Markwalder, and Hans M. Markwalder

I ntraventricular meningiomas are relatively rare. In the Mayo Clinic series, Kaplan 8 found only seven meningiomas in the ventricular system among 1454 cases of intracranial meningiomas (0.5%). Cushing and Eisenhardt 1 cited three meningiomas in the lateral ventricles among 295 cases. Kobayashi, et al., 9 found 11 cases of intraventricular meningioma (10 in the lateral ventricles and one in the fourth ventricle) among all the meningiomas seen at the Mayo Clinic between 1914 and 1967. Thus, even among the rare intraventricular meningiomas, those located in

Metastasis of prostatic carcinoma to intracranial meningioma

Case report

Ronald A. Bernstein, Kenneth A. Grumet, and Nicholas Wetzel

R eports of a tumor metastasizing to an intracranial meningioma are exceedingly infrequent; however, during the past decade their incidence has more than doubled. 1–3, 5, 8, 10, 14, 17, 19, 20, 23, 24, 28, 30, 31, 33–35, 37, 38 While there are two recent autopsy reports of prostatic adenocarcinoma within intracranial meningioma, 5, 8 this report is the first known surgically documented case. A brief review of the literature and discussion follow this case report. Case Report This 55-year-old black man was hospitalized following a 2-week history of

Association of ossified subdural hematomas and a meningioma

Case report

Joseph F. Cusick and Orville T. Bailey

T he scanty literature on calcified and ossified subdural hematomas deals largely with roentgenographic findings and the clinical manifestations of seizures and mental disturbance. Of the 34 recorded cases, 3, 4 there is little mention of the anatomical extent of the hematomas or associated pathological conditions. We are reporting the findings in a patient with massive bilateral ossified hematomas intimately associated with a huge right frontotemporoparietal meningioma. Case Report A 47-year-old woman was admitted in a comatose state. Her family
