Hemangioma of the temporal muscle.

BACKGROUND: Hemangiomas are benign vascular tumors. Because less than 1% of all hemangiomas are intramuscular, only 8 cases of temporal muscle hemangioma have been described to date. This is a case study of a 13-year-old girl who was referred to our institution because of a soft swelling located in the left temple that has enlarged progressively since birth. METHODS: CT scan, angiography and MRI showed a tumor mass lying in the temporal muscle, with homogeneous contrast enhancement. No tumor blush or feeding arteries were detected. At surgical exploration, the tumor appeared to be well demarcated. It was totally excised, sparing the surrounding temporal muscle, which did not present any sign of infiltration. Histopathologic examination showed the lesion to be a cavernous hemangioma. RESULTS: The cosmetic result was excellent, and MRI after 1 month and 2 years showed complete absence of the lesion and no evidence of recurrence. CONCLUSIONS: Although this type of tumor may be treated by various methods surgical excision yields the best results in the short and the long term. The surrounding tissue is spared as much as possible when no signs of infiltration are noted at operation, especially when involving small and functionally important muscles, as in our case.

Intrasellar paraganglioma with suprasellar extension: case report.

Paragangliomas are usually benign tumors which can be found in many sites of the body, from the base of the skull down to the pelvic floor. In the central nervous system the sellar region is very rarely involved; only three well studied cases have been reported to date. We present the cytological, histological, histochemical, immunocytochemical and ultrastructural features of an intrasellar and suprasellar paraganglioma in an 84-year-old man.

Accuracy of the analysis of multiple small fragments of glial tumors obtained by stereotactic biopsy.

To examine the reliability of the diagnoses reached on multiple small fragments of cerebral glial tumors obtained via stereotactic biopsy, samples obtained from 100 consecutive glial tumors (during real or simulated biopsy) were studied by cytology and histology. In comparison to the definitive diagnosis made on the whole tumor, a correct positive diagnosis on the biopsy sample was made by histology in 96% of cases and by cytology in 93% of the cases (with 96% correct results when combining both methods). A correct identification of the tumor type and grade was achieved by histology in 82% of cases and by cytology in 80% of the cases (with 85% correct results when combining both methods). The limits of stereotactic biopsy are related to the difficulty of identifying all of the typical tumor features on tiny tissue fragments of a pleomorphic neoplasm, such as a glioma. This study demonstrates that better results may be obtained by using both cytology and histology to study multiple stereotactic biopsy samples from glial tumors.

Solitary osteochondroma of the pedicle of L4 causing root compression. Case report.

Osteochondroma is about 50% of benign bone neoplasms and up to 15% of all primary tumours of the skeleton; metaphysis of long bones are more frequently involved with the spine being interested in 2.5-5% of all cases, usually pertaining to multiple osteochondromatosis, in which many areas of the skeleton are affected. A solitary osteochondroma of the right pedicle of L4 causing sciatalgic pain and difficulty warling and treated by surgery is presented. Only two other cases of solitary osteochondroma involving the lumbar spine have been previously reported.

Percutaneous retrogasserian glycerol rhizolysis. Observations and results about 50 cases.

Fifty patients complaining of trigeminal neuralgia have been treated by Percutaneous Retrogasserian Glycerol Rhizotomy (PRGR) from September 1983 to December 1985. In 94% of cases the procedure was successful in relieving pain with minor facial sensory loss, in 29 cases confined to the affected divisions, in 13 cases extending in an adjacent division. A herpes eruption occurred in 39 patients. A partial relapse (not requiring re-operation) verified in 12 patients. Even it firm conclusions cannot be reached as to the efficacy of this therapy, till when longer duration follow-up studies will not available, it seems to offer a manageable and very efficient way of treating trigeminal pain, constituting a valid alternative to other percutaneous techniques of trigeminal rhizolysis.

Treatment of chronic cancer pain by means of continuous intrathecal low dose morphine administration with a totally implantable subcutaneous pump. Case report.

A 59 year old man suffering from intractable chronic pain from sacral coccygeal relapsing neoplasia with pelvic invasion, operated and irradiated more than once, after a first partial success with subarachnoid intermittent morphine infusion by means of a subcutaneous reservoir, refilled transcutaneously, has been treated with continuous intrathecal low-dose morphine infusion with a totally implantable pump. This device not only greatly resolves many of the problems connected to spinal administration of morphine, but it also allows to obtain constant concentrations of the drug, so that an efficacious therapeutic action is already present at low doses, reducing the risks of overdose and supraspinal redistribution as well as the development of tolerance. This case represents the first example in Italy of the use of a completely implantable pump for this purpose.

[Neurinomas of the acoustic nerve and surgery with the suboccipital approach. A study of 70 cases].

The Authors report 70 cases of medium and large size acoustic neuromas, operated on using the suboccipital approach, the only one which allows their total extirpation. Total extirpation was performed in 77% of the patients. The Authors analyze the clinical picture, the neuroradiological diagnostic procedures and the surgical techniques used in the treatment of these lesions.
