Metastasis of invasive carcinoma of the breast to an extradural meningioma of the cranial vault

A case of metastasizing invasive carcinoma of breast to an expanding extradural frontal meningioma is presented. The peculiar tendency of meningioma to be the host tumor for carcinoma is discussed. The literature pertaining to such rare occurrences is reviewed.

The incidence of multiple meningiomas—Do solitary meningiomas exist?

SummarySince the advent of computed tomography (CT) the recognition of the occurrence of multiple intracranial meningiomas (MIM) in the same individual has been on the increase. In our material the incidence of MIM at first assessment of CT films was 20%, with distant multiplicity prevailing over the regional one. This incidence will probably change in the course of time as MIM develop not only concurrently but also consecutively. On the other hand our surgical macroscopic incidence of regional multiplicity alone was 49%. The discrepancy between the CT and surgical findings prompted us to reevaluate the CT studies of 100 consecutive patients. This reevaluation demonstrated: 1. in two cases, small meningiomas were overlooked at first assessment; 2. nineteen cases of solitary globoid meningiomas seemed to be the consequence of the coalescence of adjacent smaller masses. Thus, the CT incidence of MIM increased to 40%, with regional multiplicity prevailing over the distant one.The authors think that the aforesaid findings question the very existence of solitary meningiomas as a pathological entity. They would be the end product of a coalescence of multiple adjacent smaller growths. Accordingly, a more aggressive surgical approach is suggested to include the resection of a generous fringe of dura mater around the main tumour. As this is not always possible, or too risky, a comprehensive complement to surgery like radiotherapy could be given a reasonable randomized trial.

Brain abscess and its surgical management

A series of 56 patients with brain abscesses who were treated over a period of 23 years is reviewed. Patients with posttraumatic infections were not included. The operative mortality was 11%. Aspiration of purulent material, radical excision of the abscess, drainage of pus, or a combination of these procedures was used according to the patients condition and the location of the abscess. The relatively low mortality may be related to the preoperative condition of these patients, who were operated upon in the subacute or chronic stage of their disease. Conservative surgery, especially when functionally important parts of the brain are involved, helps to keep the postoperative neurological deficit as low as possible. Computerized tomography is of primary importance in localizing, diagnosing, and following the evolution of a brain abscess.

Hyperhidrosis and its surgical treatment

Summary111 sections of high thoracic sympathectomies in 60 cases suffering from primary palmar hyperhidrosis are reported. Surgical results and postoperative complications are discussed in detail. Complications were few in number and were of a transitory nature. No mortality occurred in our series. Various surgical and nonsurgical procedures of treatment are reviewed. Surgical intervention remains the treatment of ehoice in essential idiopathic hyperhidrosis.

Spinal cord compression in Paget's disease of bone with reference to sarcomatous degeneration and calcitonin treatment

Four cases of spinal cord compression stemming from Pagets disease of bone tissue are reported. Sarcomatous degeneration was proved in one case and in another one malignancy was deduced by computed tomography (CT) scanning. Clinical and radiologic manifestations as well as surgical management are discussed. The value of CT scanning of the spine as an aid in the evaluation of structural changes and the size of the soft tissue mass in sarcomatous degeneration of the lesion is stressed. After calcitonin administration, alleviation of pain and improvement in neurological status have occurred in two treated patients.

Aneurysmal bone cyst of spine.

SummaryFour patients (aged 5, 7, 18, and 42) suffering from spinal cord involvement due to an aneurysmal bone cyst are reported. In two cases only a preoperative radiological diagnosis was made, one of them by a CT scan. Combined surgical and radiological treatments were done in three cases with a follow-up of 16 years in one patient and 9 years in the other two. In the fourth case, presenting with a C1 lesion, after radical excision and curettage X-ray therapy was not instituted. Pathological and radiological manifestations are discussed. Therapeutic measures are reviewed.

The syndrome of the central L-3-herniated disc with special emphasis on motor involvement.

SummaryLiterature about the clinical characteristics of herniation of the lumbar intervertebral disc is profuse. Due to their predominant frequency, attention was almost entirely devoted to the L-4 and L-5 prolapses. As clinical accuracy still remains a very important target, specially in departments where myelography is not used for the diagnosis of this entity, the authors thought it of interest to describe the clinical picture of the L-3-herniated disc. Special stress is placed on the motor involvement.Fourteen cases form this series. They were all central soft herniations. Cases of spondylotic narrow spinal canal were excluded. The special features were their predominance in people above 50 years old and the compromise of the hip abductors and internal rotator muscle groups making it impossible for the patient to stand on the affected limb (Trendelenburg sign). An abnormal knee jerk was a frequent accompaniment. Contrary to common knowledge the quadriceps muscle strength was almost unaffected. Sensory disturbances were not useful for location. The L-3 section of the lower lumbar spine is the narrowest explaining the reason why 3/4 of the patients had a more or less complete cauda equina syndrome. It was therefore a very dangerous herniation that crippled quidkly, needing usually an emergency operation with all the risks involved in this older age group of patients.
