Pain and osteolysis of the thoracic spine--a case of a rare monostotic fibrous dysplasia manifestation.

We describe a case of a young farmer from Central Macedonia, Greece suffering of a mild back pain more than one year. His medical history included hypercholesterolaemia (IIa type) and two episodes of spontaneous pneumothorax of unknown origin two and three years ago respectively. A full imaging survey revealed a single osteolytic lesion at the seventh thoracic vertebra.

Spontaneous intracranial hypotension: clinical and neuroimaging findings in six cases with literature review.

Spontaneous intracranial hypotension (SIH) is an uncommon but increasingly recognized syndrome. Orthostatic headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Delayed diagnosis of this condition may subject patients to unnecessary procedures and prolong morbidity.

Magnetic resonance imaging in 120 patients with intractable partial seizures: a preoperative assessment.

The aim of this study was to describe magnetic resonance imaging (MRI) findings in patients with medically intractable epilepsy and to compare different magnetic resonance (MR) sequences in order to establish a dedicated and shorter scan time imaging protocol of choice. One hundred and twenty patients with seizures that were refractory to medical treatment were assessed by MRI with spin-echo (SE) T1, fast spin-echo (FSE) T2, fluid-attenuated inversion recovery (FLAIR), inversion recovery (IR) and contrast-enhanced T1 SE sequences. Pathological scans were acquired in 78 patients.

Efficacy of omega-3 fatty acids, atorvastatin and orlistat in non-alcoholic fatty liver disease with dyslipidemia.

Aim: To evaluate the efficacy and safety of three hypolipidemic agents in patients with non-alcoholic fatty liver disease associated with hyperlipidemia.

Methods: Patients with dyslipidemia (Fredrickson type IIb), asymptomatic persistent transaminasemia lasting 24 weeks, and evidence of hepatic fat infiltration on ultrasonography and liver biopsy were studied. Those with predominant hypertriglyceridemia received omega-3 fatty acids (5 mL thrice daily) (Group A), those with predominant hypercholesterolemia received atorvastatin 20 mg/daily (Group B), and overweight patients received orlistat 120 mg thrice daily before meals (Group C).

Cortical laminar necrosis in brain infarcts: serial MRI.

High-signal cortical lesions are observed on T1-weighted images in cases of brain infarct. Histological examination has demonstrated these to be "cortical laminar necrosis", without haemorrhage or calcification. We report serial MRI in this condition in 12 patients with brain infarcts.

CT and MR imaging findings in cerebral toxocaral disease.

We report serial MR findings in a 54-year-old woman with eosinophilic meningoencephalitis due to Toxocara canis infection, a parasitic disease contracted through exposure with soil contaminated by the eggs of the roundworm. MR imaging revealed several enhancing subcortical and white matter lesions in both lobes. Antihelminthic chemotherapy yielded marked improvement of the neurologic deficits and cerebral lesions.

Intradural extramedullary spinal canal secondary neoplasms: MR findings in 30 patients.

The purpose of this study was to describe magnetic resonance findings of intradural spinal canal secondaries and to select the best way of investigating this condition. Thirty patients with a known malignancy [breast carcinoma (n = 14), lung carcinoma (n = 10), other sites (n = 6)] and unexplained neurologic signs were studied with pre- and post-contrast T1-weighted images and T2-weighted images. Cerebrospinal fluid cytology was available in 16 patients and positive in 11 patients.

[Radiosurgical irradiation of 49 cerebral arteriovenous malformations using linear accelerator].

During 1990 we treated 49 cases of arterio-veinous malformations (AVMs) using radiosurgery. We employed 15 MV X-Ray minibeams of a Saturne 43 Linac, eight additional collimators, 6-20 mm, the O Betti armchair and the Talairach stereotactic frame. Irradiation consisted of delivering 25 Gy at the periphery of the nidus corresponding to the 60-70% peripheral isodose range.
