Metachromatic leukodystrophy (MLD) is a neurodegenerative disorder with autosomal recessive inheritance, in which cerebroside sulphate (sulphatide) accumulates in the central and peripheral nervous systems due to a deficiency of arylsulphatase A. This article presents a 2-year-old boy who had occasional shortness of breath, horizontal nystagmus and unstable gait for 3 months prior to the entry. He was admitted to our hospital due to shortness of breath, frequent apnea, generalized hypotonia and conscious disturbance. The lumbar puncture, brain CT scan, serum amino acid analysis, urine organic acid assay and nerve conduction velocity of lower extremities all showed negative findings. The electron microscopic finding of muscle elicited lipid deposition. The auditory brainstem response showed bilateral impairment. The routine EEG revealed diffuse slow waves. The brain MRI showed widespread low signals over the white matter of bilateral frontal and parietotemporal areas of the cerebral hemispheres, as well as the white matter of the bilateral cerebellar hemispheres, and the brain stem in the T1-weighted image corresponding the high signals in T2-weighted image. The blood leukocyte lysosomal enzyme activity test revealed arylsulphatase A deficiency. Rapid progressive neurological deterioration was noted since admission. Unfortunately, the patient expired due to respiratory failure in the final.

Pseudocysts of the pancreas are a rare cause of a mediastinal mass. They are clinically characterized by the combination of thoracic symptoms (shortness of breath, dysphagia, pleural effusions) with complaints in the upper abdominal quadrants and weight loss. The diagnosis is usually made by CT scan or MRI including upper abdominal views. Internal drainage via an abdominal route performed either as cystogastrostomy or cystojejunostomy is the treatment of choice.

We present a rare case of aortitis syndrome associated with dilatation of aorta and coarctation-like effect due to the intraluminal flap formation originated from dissected wall of the aorta. A 31-year-old woman was admitted to our hospital complaining of shortness of breath, palpitation and cough. On admission, her physical status showed congestive heart failure and hypertension of upper extremities and hypotension of lower extremities. Bruits were audible over the neck, the anterior chest and the back. Serological studies showed active inflammation. Chest X-ray film showed upper mediastinal widening, cardiomegaly and pulmonary edema. Aortitis syndrome was strongly suggested by these clinical findings, so that prednisolone therapy was started on 3rd hospital day. Special examinations were performed several days later when inflammatory changes showed a tendency to improve. Chest CT scan, RI angiography and MRI studies showed an aneurysmal dilatation from the ascending aorta to the mid-thoracic aorta. Aortography demonstrated a flap at the terminal portion of this aneurysmal dilatation and grade II (Sellars) aortic regurgitation. There was a pressure difference of 80 mmHg between the parts abutting cranial and caudal sides of the flap. A surgical operation was, then, performed to correct the pressure difference. The dissected wall was extruded toward the aortic lumen creating a flap (2 cm in length). This flap was resected and an artificial graft was inserted. Histologically, the flap consisted of adventitia, media and intima.(ABSTRACT TRUNCATED AT 250 WORDS)

Thymoma with thrombocytopenia has rarely been reported. We recently encountered a case of operated invasive thymoma with thrombocytopenia. A 74-year-old woman was admitted to our hospital with the chief complaint of 'shortness of breath' and general fatigue. Chest X-ray, CT and MRI showed a mass 5 x 5 cm in size at the anterior mediastinum. In hematological test, a significant decrease in platelets count (1.6 x 10(4)/mm3) and a increase in PA-IgG (134.5 ng/10 cells) were found. This finding suggests that thrombocytopenia is due to immunological abnormality. Steroid therapy (prednisolone 60 mg) was begun but was not effective and then, extended thymectomy was performed. After operation, prednisolone (30 mg) therapy was continued. Although prednisolone therapy was gradually decreased and stopped, platelets count was gradually increased 10.8 x 10(4)/mm3. Extended thymectomy and steroid therapy were effective.

We report a case of diaphragmatic paralysis after herpes zoster. A 82-year-old woman developed shortness of breath on effort after about two months of a typical herpes zoster eruptions affecting the C4 and C5 dermatomic areas on the right side. A chest x-ray showed an elevated right diaphragm. The diaphragmatic evoked potential by stimulation of the right phrenic nerve at the posterior border of the sternocleidomastoid muscle was not elicited. Chest CT and cervical MRI were normal. The viral antibody titers of herpes zoster were elevated in the serum. Cervical herpes zoster should be considered as a possible cause of hemidiaphragmatic paralysis.

As many as 10% to 20% of patients with disseminated hemangiomas involving vital organs fail to respond to conventional treatment with steroids, radiotherapy, laser or cyclophosphamide. For the last years, interferon-alpha-2 has been successfully used to treat complicated giant hemangiomas, because of its ability to inhibit endothelial cell proliferation. We report the case of a 3-months-old infant presenting with a giant cervicofacial hemangioma with extension to the chest wall and larynx, causing episodes of severe respiratory distress. CT scan and MRI revealed a second vascular lesion measuring 24 x 16 mm in the liver. Initial treatment with corticosteroids (prednisolone at a dose of 1-3 mg/kg/daily) and endoscopic laser barely improved the symptoms and the patient presented more episodes of shortness of breath requiring admission to the ICU. Interferon therapy was started at a dose of 3 million units/m2/every other day and was continued for 9 months. At the completion of the therapy, there was complete regression of the hemangioma. Four months later, the patient is asymptomatic. No side-effects were presented for hyperthermia when the treatment was started resolved with antithermics. Blood tests were always within the normal range.

Pheochromocytoma is a rare entity. When it presents during pregnancy, rapid recognition and diagnosis are crucial in order to avoid the maternal and fetal morbidity and mortality associated with severe, uncontrolled hypertension. Difficulties arise from the differential diagnosis of pre-eclampsia. We report two patients operated on for pheochromocytoma during pregnancy. The first patient developed new-onset hypertension in early pregnancy. Prior to presentation, there had been non-specific signs of endocrine disorder, namely a mild diabetes, but no hypertension requiring medication. The second patient sought medical care for irregular heartbeat, shortness of breath, and fatigue during the 6th week of pregnancy. She was found to be hypertensive; diagnostic evaluation revealed substantially increased catecholamine levels. The diagnosis was made by elevated urinary catecholamines and by MRI scan as well as ultrasonography, both of which demonstrated an adrenal mass. Both patients underwent surgical extirpation of the affected adrenal gland. The procedure was performed laparoscopically in the case of the second patient. Pre-operatively, both patients were pre-treated with alpha-blockade followed by secondary beta-blockade. Patient two also received methyldopa for control of hypertension. Both patients were readily weaned from antihypertensive medications post-operatively, with complete resolution of hypertension within a few hours. Each pregnancy progressed normally to term.

A 43-year-old man presented with fluctuating symptoms of weight gain, shortness of breath, pretibial oedema, associated with anxiety and memory disturbances. Laboratory investigation revealed an adrenocorticotropin (ACTH)-dependent cyclical Cushing's syndrome characterised by remarkable variations in urinary cortisol excretions ranging from 27 to 28,050 nmol/ 24 h. Magnetic resonance imaging (MRI ) of the pituitary was normal and ectopic ACTH production was suspected. A tumour in the right anterior mediastinum was revealed on octreotide receptor scintigraphy, which had initially been overlooked on computed tomography (CT) scanning. A thymic carcinoid tumour was suspected, which was supported by increased levels of urinary serotonin, while platelet serotonin and urinary 5-hydroxyindoleacetic acid levels were normal. The tumour was removed surgically and histological examination revealed an atypical thymic carcinoid tumour. Postoperatively, the patient's symptoms disappeared rapidly. He underwent external radiotherapy and is still free of symptoms after almost two years of follow-up. For clinical practice, a cyclical Cushing's syndrome should be suspected in any patient with clinical signs of Cushing's syndrome but normal biochemistry. Repeated measurement of urinary cortisol excretion is then required to establish or rule out the diagnosis.

The objective of this study was to evaluate the clinical safety of intravenous gadolinium-based contrast media used in patients who underwent MRI at a single institution. Acute adverse reactions to intravenous gadolinium-based contrast media used for MRI at the Princess Margaret Hospital, Hong Kong, SAR, from January 1999 to November 2004 were recorded in an incidence log book. The medical records of patients' demographics were retrospectively reviewed and the nature, frequency and severity of the adverse reactions were investigated and documented. The incidence of acute adverse reactions to intravenous gadolinium-based contrast media was 0.48% (45 patients with 46 adverse reactions). The severity of these adverse reactions were 96% mild, 2% moderate (one patient developed shortness of breath that required oxygen supplementation and intravenous steroidal management) and 2% severe (one patient developed an anaphylactoid reaction, but successfully recovered through timely resuscitation). No patients were recorded as having contrast extravasation and none died as a result of any adverse reaction. Among the 45 patients who developed adverse reactions, three patients (6.7%) had prior adverse reactions to iodinated contrast media, three (6.7%) had prior reactions to a different gadolinium-based contrast agent, one (2%) had asthma and nine (20%) had a history of drug/food allergy. Overall, 41% of the adverse reactions were not documented in the final MRI report or the clinical medical records. Gadolinium-based contrast media are safe and well tolerated by the vast majority of patients. In our study, the adverse reaction rate (0.48%) and the incidence of severe anaphylactoid reaction (0.01%) concur with those reported in the literature. Although most of the symptoms are mild and transient, these adverse reactions must be accurately documented and managed.
