We present a very rare case of a 29-month-old boy with acute onset right abducens nerve palsy complicated by inferior petrosal sinus septic thrombosis due to mastoiditis without petrous apicitis. Four months after mastoidectomy, the patient fully recovered from an esotropia of 30 prism diopters and an abduction limitation (-4) in his right eye.

OBJECTIVETo explore the effect of urokinase and low molecular weight heparin in children with nephrotic syndrome complicated with intracranial venous thrombosis.

METHODSUrokinase and low molecular weight heparin were administered to the 5 patients intravenously. The initial dose of urokinase was 2000 - 4000 U/(kg.d), the initial pulse dose was 20 000 - 40 000 U given within 15 - 30 minutes, and the left was infused by using a pump, from the second day 2000 U/(kg.d) urokinase was infused daily for 3 to 7 days. During the treatment thrombin time (TT), activated partial thromboplastin time (APTT) were tested 3 times every week, with particular attention to bleeding. Low molecular weight heparin 100 - 120 AXaIU/kg, 1 or 2 times per day was hypodermally injected for a course of two weeks. Anti-platelet drugs: long-term oral administration of dipyridamole 3 - 5 mg/(kg.d) was applied 2 - 3 times every day for 3 months.

RESULTSThe clinical symptoms disappeared after one month of the combined therapy of urokinase, low molecular weight heparin and dipyridamole in 5 cases of nephrotic syndrome complicated with intracranial venous thrombosis in children, the plasma viscosity returned to normal in 1 month, activated partial thromboplastin time, prothrombin time, fibrinogen degradation products returned to normal in 1 to 2 months, venous thrombosis disappeared after 1 to 3 months in head CT or MRI examination, showing the cerebral venous sinus thrombosis complete recanalization without relapse cases in follow-up.

CONCLUSIONThe early application of urokinase and low molecular heparin and anti-platelet coagulation drugs was effective. The early diagnosis, treatment and prevention of intracranial vein thrombosis in patients with nephrotic syndrome is important.

Skull base osteomyelitis (SBO) is difficult to diagnose when a patient presents with multiple cranial nerve palsies but no obvious infectious focus. There is no report about SBO with septic pulmonary embolism. A 51-yr-old man presented to our hospital with headache, hoarseness, dysphagia, frequent choking, fever, cough, and sputum production. He was diagnosed of having masked mastoiditis complicated by SBO with multiple cranial nerve palsies, sigmoid sinus thrombosis, and septic pulmonary embolism. We successfully treated him with antibiotics and anticoagulants alone, with no surgical intervention. His neurologic deficits were completely recovered. Decrease of pulmonary nodules and thrombus in the sinus was evident on the follow-up imaging one month later. In selected cases of intracranial complications of SBO and septic pulmonary embolism, secondary to mastoiditis with early response to antibiotic therapy, conservative treatment may be considered and surgical intervention may be withheld.

The onset of pregnancy may predispose women to a variety of neurological diseases due to changes in their hemodynamics, hormonal effects, and complications associated with childbirth. The spectrum of neurological disorders associated with pregnancy and childbirth include hypertensive intracerebral hemorrhaging, posterior reversible encephalopathy syndrome (PRES) (secondary to eclampsia), Wernicke encephalopathy, cerebral venous sinus thrombosis, Sheehan's syndrome, hypoxic ischemic encephalopathy (secondary to pulmonary amniotic fluid embolism), multifocal infarctions, and extra-potine myelinolysis. The recognition of the various imaging findings of these diseases, along with the clinical presentations, should aid in their early diagnosis and prompt treatment. The purpose of this pictorial assay is to describe the characteristic CT and MR findings of these diseases with a literature review to explain the mechanisms and clinical symptoms.
