[Rhino-cerebral fungal infection successfully treated with supplementary hyperbaric oxygen therapy].

Rhino-cerebral fungal infections are rare and difficult disorders to cure. We report the case of a woman presenting a left trigeminal neuralgia complicated by ophthalmoplegia and blindness. MRI demonstrated a lesion of the left orbital apex with extension into the cavernous sinus. Fungal infiltration (aspergillosis or mucormycosis), was seen on biopsy. High-dose liposomal Amphotericin B (5mg/kg/day) for six weeks was unsuccessful. Adjunctant hyperbaric oxygen therapy led to clinical and radiological improvement. Hyperbaric oxygen therapy is discussed in the medical management of rhino-cerebral yeast abscesses.

A relapsing remitting lymphocytic hypophysitis.

Lymphocytic Hypophysitis is a rare autoimmune disease of the pituitary presenting mainly with features of a mass lesion and loss of pituitary function. Its course is quite unpredictable and its treatment is still controversial as experience in the field remains scarce. We describe a 45 year-old woman with a history of recurrent fever and meningeal symptoms who was referred 3 years later to our department for pituitary insufficiency. Hormonal studies revealed an anterior pituitary deficiency and autoimmune thyroiditis. Pituitary hypertrophy as evidenced by magnetic resonance imaging showed complete regression upon hydrocortisone substitution therapy. Two years later, fever and meningeal symptoms recurred as well as pituitary hypertrophy. Cerebrospinal fluid analysis revealed an aseptic lymphocytic meningitis. Pituitary biopsy confirmed the diagnosis of LH. The patient was started on prednisone 70 mg per day. She improved clinically and radiologically and remained free of symptoms thereafter. At a recent follow up the MRI showed an empty sella turcica. Hereby we illustrate a yet unreported pattern of LH presenting as a recurrent aseptic meningitis. We also describe one of the long-term course of the disease which is still unpredictable.

[Value of of fine-needle aspiration cytology and MRI in parotid gland masses].

INTRODUCTION: The objective of our study was to discuss the valve of fine-needle aspiration cytology (FNAC) and magnetic resonance imaging (MRI) in the diagnosis and treatment of parotid gland masses. MATERIALS AND METHODS: Forty patients were included in the prospective study. They had undergone clinical examination, FNAC and MRI before parotidectomy. The results of these examinations were compared with the corresponding histopathological diagnosis. RESULTS: When it is positive, FNAC is a good examination of malignant tumours (sensitivity 67%, specificity 79%, positive predictive value 86%, negative predictive value 100%). The MRI allows a good assessment of the tumoural mass and its anatomical relationships (sensitivity 55%, specificity 86%, positive predictive value 89%, negative predictive value 75%). If the T2 sequence shows reduced density (p < 0.05) or in case of bad limitation (p = 0.004), a malignant character is strongly suspected. CONCLUSION: In cases of parotid gland mass, where surgical intervention is necessary, there is no need of special investigations: however FNAC and MRI allow us to anticipate what operation will be required.

Reversible posterior leukoencephalopathy syndrome in hepatitis C virus-positive long-term hemodialysis patients.

Chronic hepatitis C virus (HCV) infection is quite prevalent in long-term hemodialysis (HD) patients. Patients who are candidates for renal transplantation might be treated, before grafting, with interferon-alpha (IFN-alpha). Among 39 HCV-positive long-term HD patients treated with IFN-alpha, we observed three cases of reversible posterior leukoencephalopathy syndrome (PLES). PLES included headaches in three patients, confusion in three patients, cortical blindness in two patients, visual hallucinations in one patient, seizures in three patients, and respiratory distress in one patient in a context of fluid overload and severe hypertension in all cases. The three patients were receiving IFN-alpha and recombinant erythropoietin therapies simultaneously for de novo anemia. Contrast-enhanced computed tomography scan or magnetic resonance imaging showed low-density areas in the occipital lobes (in three patients), frontal lobes (in one patient), and temporal lobes (in one patient). After withdrawal of IFN-alpha and recombinant erythropoietin therapies, hemodiafiltration, and symptomatic treatment of seizures and hypertension, PLES was reversible within 1 week in one patient, 10 days in one patient, and 2 months in the third patient. Our case reports show the occurrence of reversible PLES in HCV-positive long-term HD patients treated with IFN-alpha. Physicians caring for HCV-positive long-term HD patients treated with IFN-alpha need to be particularly cautious when these patients receive simultaneously recombinant erythropoietin and when IFN-alpha therapy induces a weight loss, which indicates a reduction in dry weight.
