Cerebral venous sinus thrombosis as a complication of primary varicella infection in a child, case report.

ABSTRACT:

Introduction and importance

Chickenpox (Varicella) is a benign illness caused by varicella-zoster virus, predominant in childhood.Chicken pox related neurological complications are seen in less than 1% cases of chickenpox.Cerebral Venous thrombosis due to primary (VZV) infection is very rare, and it may occurs secondary to primary or re-activation the virus.

Case presentation

We report a case of 5-year-old female complained of ataxia, vomiting, headache, and drowsiness 7 days after the onset varicella zoster infection. She had vesicular lesions with scab over the trunk and limbs.

Clinical discussion

Neurological examination revealed left hemiparesis.Her blood counts and metabolic parameters were normal.Computed tomography brain showed hemorrhagic infarct in the left temporo-parietal region. Coagulation profile was normal. Magnetic resonance imaging (MRI) brain revealed hemorrhagic infarct in the same region. Magnetic resonance Venogram showed thrombosis of left transverse sinus and sigmoid sinus and internal jugular vein.VZV- IgG antibody was positive but CSF VZV PCR (Polymerase chain reaction) was found to be negative.Intravenous acyclovir for 15 days, and low-molecular-weight heparin for 3 days overlapped with oral Warfarin for 3months,. After 3 months follow up, the patient experienced a complete recovery. MRI repeated after 3 months showed recanalization of the sinuses.

Conclusion

The pathogenic link of occurrence of CSVT after VZV infection is unclear, but some articles showed that it is related to direct endothelial damage by the virus.Early recognition of this complication of VZV infection and prompt treatment is essential to prevent catastrophic complications.

Project description:BackgroundVascular complications of acute pancreatitis are common. Splanchnic thrombosis accounts for 11% of these complications, whereas extrasplanchnic thrombosis remains a rare entity. These complications are associated with high morbidity and mortality. Diagnosis is established on the basis of clinical and radiological evaluation, especially computed tomography. Renal vein thrombosis has been reported previously, but only in association with thrombosis of the inferior vena cava. To our knowledge, renal vein thrombosis without inferior vena cava thrombosis has never been reported in the literature. We report a case of a woman who developed acute pancreatitis complicated with splanchnic thrombosis and renal vein thrombosis with a patent inferior vena cava.Case presentationA 48-year-old Moroccan woman with no significant past medical history presented to our emergency department with worsening epigastric pain and vomiting. Her physical examination was notable only for moderate epigastric tenderness. She was apyrexic and had no jaundice or any features of liver failure. An initial computed tomographic scan showed Balthazar grade C pancreatitis with multiple splanchnic thromboses involving the portal vein, superior mesenteric vein, and left renal vein and enteromesenteric venous infarct with no signs of bowel perforation. The inferior vena cava was patent. Therapeutic anticoagulation and analgesia were started with resumption of enteral feeding 72?h later. The result of a thrombophilia screen was negative. Two months later, the patient was admitted to the intensive care unit with acute liver failure. Computed tomography of the abdomen showed worsening ischemic liver lesions and no signs of bowel perforation. Biochemical analysis showed acute hepatitis with hepatocellular insufficiency. The clinical evolution was unfavorable, and the patient died 48?h later.ConclusionsAssociation of splanchnic and renal vein thrombosis without inferior vena cava thrombosis as a complication of acute pancreatitis has never been reported before. There are no specific aspects of management of this complication; therapeutic anticoagulation and symptomatic treatment are the main measures used owing to the lack of available organs for liver transplant. The prognosis depends on the consequences of splanchnic thrombosis and their complications.
