Pulmonary hypertension in rheumatoid arthritis.

Using Doppler echocardiography (DE), we measured pulmonary arterial systolic pressure (PASP) in rheumatoid arthritis (RA) patients without coexisting cardiopulmonary diseases. Accepting the normal upper limit of PASP as 30 mmHg, we found elevated PASP in 11 out of 40 (27.5%) RA patients, values being mostly 30-40 mmHg, indicating mild pulmonary hypertension (PHT). Although estimation of PASP by DE is not as reliable as cardiac catheterisation, it is possible that mild elevations in PASP may contribute to the high incidence of cardiovascular events not explained by traditional cardiac risk factors in patients with RA. Long-term follow-up will be obviously necessary to ascertain the impact of mild PHT on the prognosis and mortality rate of RA patients.

Proton MR spectroscopy in the diagnosis and differentiation of encephalitis from other mimicking lesions.

In this study, proton magnetic resonance spectroscopy (1H MRS) findings of encephalitis were reported. For comparison, other lesions mimicking encephalitis on conventional magnetic resonance (MR) imaging were included in the study. These lesions consisted of acute infarctions and low grade infiltrative gliomas. The 1H MRS findings of encephalitis and gliomas were almost the same whereas infarctions revealed high lactate levels differentiating the disorder from other two pathologies. The differentiation of encephalitis and gliomas based on MR findings could reliably made with short time follow up MR examinations where gliomas tend to grow in contrast to encephalitis which showed regression.

Isolated pontine infarction due to rhinocerebral mucormycosis.

We report a patient with rhinocerebral mucormycosis whose initial central nervous system involvement was isolated pontine infarction due to basilar arteritis caused by the fungus. The patient was diagnosed and followed by MRI and CT and basilar arteritis was demonstrated well on MRI studies. Involvement of the skull base was shown on CT in the later stage of the disease. The unusual initial presentation of the infection is discussed.

Varix of the inferior pulmonary vein: computed tomography and magnetic resonance angiography findings.

A 37-yr-old male presented with a 2-week history of intermittent episodes of mild haemoptysis. Computed tomography and magnetic resonance imaging revealed a varix of the inferior pulmonary vein. The diagnosis was confirmed using magnetic resonance angiography and conventional angiography. This condition is relatively rare, and few cases have previously been demonstrated by means of magnetic resonance imaging and angiography.

Deep calcarine sulcus and prominent calcar avis.

MR imaging examinations of the brain 100 consecutive patients, ages ranging from 1 year to 66 years, were evaluated in order to investigate the frequency of a deep calcarine sulcus and prominent calcar avis. Twenty-four cases (24%) were found with a deep calcarine sulcus and prominent calcar avis. These were bilateral in four patients, and unilateral in twenty. Fifteen of the unilateral cases demonstrated a right-sided involvement, and remaining five were left-sided. A deep calcarine sulcus and prominent calcar avis should be distinguished from disorders of neuronal migration and organization such as schizencephaly and heterotopia. Also, based on our findings in this study, we speculate that it is the deep calcarine sulcus and prominent calcar avis which creates the appearance of the so-called accessory occipital ventricle.

Isolated oculomotor nerve paralysis in Lyme disease: MRI.

Lyme disease is a cause of illness involving multiple organ systems, including, in 10-15 % of cases, the nervous system. Peripheral radiculoneuritis, cranial neuritis, encephalitis and myelitis are among the neurological manifestations found in the second and third stages. We present the MRI findings in isolated oculomotor nerve involvement by Lyme disease and discuss the differential diagnosis.

Prominent occipitotemporal vein: an association with temporal lobe epilepsy?

Eight patients with a prominent occipitotemporal vein on MR imaging, and ipsilateral temporal lobe epilepsy are reported. The ages of the patients ranged from 2 months to 12 yr. There were five males and three females. Abnormal electroencephalographic (EEG) findings were evident in all the patients, and they had focal seizures. MR images revealed prominent (4 mm or more in width) occipitotemporal veins in the ipsilateral sides, and otherwise unremarkable findings. Three similar patients have previously been reported in the literature. We speculate that a prominent occipitotemporal vein may represent a consequence or a cause of a certain type of temporal lope epilepsy. Further clinicoradiologic studies are required to clarify the question raised by these observations.

Hypoplastic lumbar pedicle in association with conjoined nerve root MRI demonstration.

We report a case of aberrant hypoplastic pedicle of the fourth lumbar vertebra and ipsilateral conjoined nerve root. Ipsilateral retroisthmic laminar defect, dysplastic lamina and transverse process, enlargement of neural foramen, hypoplasia of superior and inferior articular facet were present as associated with other neural arch anomalies. The extent of these anomalies was well demonstrated by MR imaging.

Spinal cord compression due to costal Echinococcus multilocularis.

We present computerized tomography (CT) and magnetic resonance imaging (MRI) findings of a costal hydatid cyst (Echinococcus multilocularis) causing spinal cord compression. The hydatid disease was proved histologically. MRI was not only very useful for determining the spinal extension of the disease by its multiplanar imaging capability, but also gave important information about the texture of the cyst, thus aiding the preoperative diagnosis.
