In a 21-year-old Caucasian women with von Hippel-Lindau disease, norepinephrine-producing adrenal pheochromocytoma was identified as the underlying cause of severe hypertension. She was found to have extremely elevated levels of circulating renin and aldosterone, and she was markedly hypokalemic. Administration of captopril further enhanced renin secretion, while her blood pressure improved. The patient became normokalemic following tumor removal, and her blood pressure decreased to normal levels with reestablishment of normal circadian blood pressure rhythm. This case demonstrates that, in the absence of renovascular or malignant hypertension, pheochromocytoma can be the underlying cause for the clinical syndrome of hypertension associated with severe hypokalemia and hyperreninemic hyperaldosteronism.

A 27-year-old female was referred with an abdominal mass. Examination revealed a non tender firm mass in the right flank and hypertension (200/100 mmHg). An angiomyolipoma was suspected on computed tomography and arteriography and a radical nephrectomy was performed. On cut section, the kidney was occupied by a well-capsulated, grayish tumor measuring 10 x 9 cm. Pathological diagnosis was a renal hemangiopericytoma without involvement of the capsule. Her blood pressure has normalized after the operation. She has no evidence of recurrence after 18 months' follow-up.

Renal ultrasound examination, performed following a urinary tract infection in a 4.5-year-old girl with triple X syndrome, showed multiple echogenic foci at the corticomedullary junction in both kidneys. She was asymptomatic but had hypertension with echocardiographic evidence of left ventricular hypertrophy. Computerised tomographic scan revealed foci of calcification in the kidneys, spleen and pancreas. On biopsy calcification was found in the internal and external elastic laminae of the superficial temporal artery and in the internal elastic lamina of a renal arcuate artery. Intimal fibrosis was mild and focal. No other arterial calcification was demonstrated radiographically or by ultrasound. Biochemical and hormonal profiles revealed no abnormality except hypercalciuria. The aetiology and prognosis of this child's condition are unknown. Although similar ultrasound and histological appearances have been described in pseudoxanthoma elasticum and in idiopathic arterial calcification of infancy, there is no evidence that the child has either of these conditions.

A 39-year-old woman presented with a 2-month history of repeated severe headache, nausea and diplopia. On admission she was obese with bilateral papilledma and abducens weakness. Mass lesion and sinus thrombosis were ruled out by brain CT and angiography. CSF pressure was normal initially. CSF pressure fluctuated with menstrual cycle, sometimes showing over 600 mmH2O with worsening of the symptoms. She was diagnosed as benign intracranial hypertension (BIH). Diuretics did not improve the symptoms, and visual disturbances ensued and deteriorated. A spinal subarachnoid space-peritoneal shunt was inserted to control CSF pressure, showing rapid improvement of headache and diplopia but visual disturbances remained almost unchanged. Optic nerve sheath fenestration was performed without improvement of visual deterioration. We postulated multiple factors such as obesity, menstrual abnormality, iron deficiency anemia and analgesic drugs played important roles to produce BIH in this case. Careful quantitative perimetry should be done to decide a suitable time for surgical treatment in BIH.

A 75-year-old woman suffered from intermittent high-grade fever and hypertension without any focal sign. Serum lactic dehydrogenase (LDH) was markedly elevated. The fever was resistant to antibiotics and temporarily sensitive to prednisolone. She had heart failure and died. Postmortem examination revealed intravascular proliferation of B lymphocytes, indicative of the diagnosis of intravascular lymphomatosis. The clinical diagnosis is usually very difficult because of the absence of pathognomonic clinical manifestations.

Stevens-Johnson syndrome is an acute, inflammatory eruption of the skin and mucous membranes often associated with drug ingestion. A forty-five-year-old woman showed symptoms consistent with Stevens-Johnson syndrome two days after indapamide therapy was begun for the treatment of hypertension. Initial manifestations consisted of headaches, sore throat, cough, and symptoms of conjunctival injection, including redness and swelling. Approximately two weeks later, the patient noted skin eruptions involving the conjunctiva, lips, face, neck, trunk, and extremities. She was treated with cool compresses, antiseptics, ophthalmic antibiotics and steroids, and oral prednisone. Symptoms began to resolve approximately eight days after indapamide was discontinued and treatment was begun. Although rare, Stevens-Johnson syndrome should be considered in the differential diagnosis of a patient with a history of indapamide ingestion who presents with malaise, fever, and skin eruptions.

A phenotypic female presented initially at the age of 17 years with amenorrhoea and delay of sexual development. Karyotype was male, 46 XY, and as gonads were absent, a diagnosis of congenital anorchia was made. The patient was treated with oestrogen. At the age of 23 years, she re-presented with tall stature and hypertension. She then had normal female habitus but absent pubic and axillary hair. Re-investigation showed that sex steroids and cortisol were absent and established the diagnosis as 17 alpha-hydroxylase deficiency. Treatment with hydrocortisone rapidly corrected the hypertension. Ultrasound examination confirmed the absence of gonads but showed that a small uterus was present. Measurement of serum cortisol is important for recognition of such patients, but further measurements of sex steroids, particularly progesterone, are needed to prove the diagnosis. We have found no previous reports of absent gonads in 17 alpha-hydroxylase deficiency. The association remains unexplained.

The cerebral changes are described in a woman of 54 who suffered from Binswanger's encephalopathy: there were no signs or symptoms of chronic arterial hypertension. The disease presented as dementia of about 3 years duration. Computed tomography of the brain 2.5 years before her death showed bilateral widespread hypodense lesions in the cerebral white matter. She died of an asthmatic attack. Autopsy disclosed extensive bilateral degeneration of the central white matter, lacunes and gliosis. Severe obliterative arteriolosclerosis occurred in the meningeal vessels and those supplying the affected parts of the brain. Light microscopy showed that the most severe lesions occurred in the arterioles. Immunohistochemistry demonstrated profound extravasation of plasma proteins chiefly albumin, indicating dysfunction of the blood-brain barrier. Thus, the lesions characteristic of Binswanger's encephalopathy may develop in the absence of chronic arterial hypertension. Additional pathogenic factors, possibly genetic predisposition to vascular injury may play a role in the development of this condition.

A 47-year-old woman with diabetic gastroparesis, on treatment with domperidone, a dopamine-receptor antagonist, was admitted to the hospital in coma, with high blood pressure and nonreactive pupils. She then developed high fever. Her condition progressively worsened for two days, when muscle rigidity was noted and creatine phosphokinase was greater than 2000 U/liter. A diagnosis of neuroleptic malignant syndrome was made, and the patient was given dantrolene with prompt and complete resolution of all signs and symptoms. Subsequent inquiry revealed a distant past history of positive muscle biopsy for malignant hyperthermia, obtained after the diagnosis had been made in a family member. This case suggests that domperidone may induce neuroleptic malignant syndrome and that patients with malignant hyperthermia are at increased risk for this complication.

A 54-year-old woman with pseudoxanthoma elasticum presented with tight mitral stenosis with thickened and restricted mitral valve leaflets. She initially revealed systemic hypertension and moderate mitral regurgitation due to mitral valve prolapse. One year after the start of treatment for hypertension, thickening of the mitral valve gradually progressed and she showed tight mitral stenosis without regurgitation. It was considered that another differential diagnosis must be added to the uncommon causes of mitral stenosis.
