Venous infarction secondary to septic cavernous sinus thrombosis.

A 65-year-old woman with poorly controlled diabetes presented bilateral miosis, bilateral abducens nerve palsy, and left hemiparesis. On MRI, cavernous sinus thrombosis, subdural empyema and hemorrhagic infarction in the frontotemporal lobe were detected. Cerebral angiogram revealed filling defect in the cavernous sinus with venous congestion but no involvement of internal carotid artery. Postmortem examination demonstrated hemorrhagic infarction in the right frontotemporal lobe as well as hemorrhagic necrosis of the pituitary gland. It should be noted that venous congestion due to cavernous sinus thrombosis may cause these complications.

Septic cavernous sinus thrombosis due to Streptococcus constellatus infection.

Adult septic cavernous sinus thrombosis (CST) due to Streptococcus constellatus infection has not been reported. We report a case of CST due to S. constellatus in a 39-year-old man who had typical presentations of septic CST including headache, fever, and ophthalmoplegia, with an evolving course for 10 days before he was sent to our emergency room. Cranial magnetic resonance imaging (MRI) study revealed CST, which was confirmed by cerebral angiography study. Multiple positive blood cultures grew viridans streptococci and further species identification with conventional methods, API-20 STREPT system analysis, and polymerase chain reaction sequencing of bacterial 16S rRNA revealed S. constellatus. The presence of sphenoid sinusitis in this patient was also demonstrated by cranial MRI study, and the presence of meningitis by meningeal irritation signs and inflammatory cerebrospinal fluid (CSF) findings. Chronic alcohol consumption for more than 10 years was the only predisposing condition to this infection. He had a full recovery after 6 weeks of intravenous penicillin G therapy (24 x 10(6) U/day). Almost complete regression of cavernous sinus lesion and resolution of sphenoid sinusitis were shown on follow-up cranial MRI study about 6 months later.

Acute dural venous sinus thrombosis without brain parenchymal abnormality: assessment with cerebral blood volume using dynamic susceptibility contrast magnetic resonance imaging.

We report results applying the dynamic susceptibility contrast (DSC) magnetic resonance (MR) technique to a patient with dural venous sinus thrombosis (DVST) of the right transverse-sigmoid sinus without brain parenchymal abnormality. The DSC-MR technique clearly demonstrated increased regional cerebral blood volume of the right temporo-parieto-occipital region adjacent to a right transverse-sigmoid sinus thrombosis in a patient with DVST without cerebral edema or hemorrhage.

Otogenic lateral sinus thrombosis in children.

INTRODUCTION: The clinical picture of lateral sinus thrombosis (LST) has changed with the advent of antibiotics, as have the utility of various diagnostic tests. LST may appear in children as a complication of acute otitis media, but nowadays it is more frequently encountered in adults with long-standing chronic ear disease. METHOD: A retrospective study of all the pediatric patients with LST between 1982 and 1997. RESULTS: Thirteen cases of LST were diagnosed and treated by our department. In six cases, LST was due to acute otitis media and in the remaining cases it was due to chronic otitis media. Headache, fever, aural discharge and mastoid tenderness were the most frequent findings in these patients and four patients were initially diagnosed with meningitis. In the majority of the patients, LST was accompanied with other intracranial complications, such as perisinus abscess, brain abscess and meningitis. One patient with multiple brain abscesses, unresponsive to several drainage procedures, died. The other patients recovered and have since been followed-up as out-patients. CONCLUSION: LST may be difficult to diagnose due to previous antibiotic treatment and to the overlap of clinical findings with other entities such as meningitis. Despite the value of modern imaging techniques in the investigation of the disease, a high index of suspicion based on the clinical picture is warranted. Our results are consistent with those of other recent studies, who found that mortality of LST has dropped below 10%.

Low-oestrogen oral contraceptives as a major risk factor for cerebral venous and sinus thrombosis: evidence from a clinical series.

Cerebral venous and sinus thrombosis (CVST) is still considered a severe clinical problem that is difficult to diagnose and manage and is linked to a poor prognosis. Nonetheless, conventional cerebral angiography and magnetic resonance imaging (MRI), or more recently, MR angiography allow a more rapid and precise diagnosis, and prognosis has improved with the use of anticoagulant treatment. We report 23 cases of CVST consecutively admitted to the Institute of Neurology of the University of Parma during the period 1990-1997. In all cases diagnosis was confirmed by means of MRI or conventional angiography of brain vessels. Among the patients, 22 were female and 1 was male. In all patients, plasma levels of protein C, protein S, antithrombin III (ATIII) and antiphospholipid antibodies (APA) were evaluated. In 15 of 23 patients, the presence of factor V Leiden mutation was also determined, and found positive in 3 patients (20%). Of the 22 female patients, 15 (68%) were on low-oestrogen (containing less than 50 microg oestrogen) oral contraceptive (OC) treatment. This percentage of OC use by patients with CVST is much higher than that of the rest of the female Italian population. OC use was associated with the presence of factor V Leiden mutation in two cases, with a deficiency of protein C in 1 case and a deficiency of protein S in another.Whether low-oestrogen Ocs may induce cerebral thromboembolic events is an open matter. According to our data, it may be argued that Ocs, even if at low oestrogen content, represent a major risk factor for CVST. The use of Ocs, as is the case for systemic venous thromboembolic events, may further increase the risk of CVST in women carrying the factor V Leiden mutation or other inherited hyperthrombotic conditions.

Coronary sinus thrombosis after cannulation during cardiopulmonary bypass.

Coronary sinus thrombosis was found at autopsy of a boy who had undergone intracardiac repair of tetrology of Fallot. During the operation persistent left superior vena cava was cannulated through the right atrium via the coronary sinus. There was also evidence of myocardial infarction in the region of the interventricular septum.

Dural sinus thrombosis.

The outlook for cerebral venous and sinus thrombosis, once considered a uniformly fatal disorder, has been dramatically improved by the advent of sophisticated neuroradiology and effective management. Many potentially treatable underlying disorders are now recognized. Presentation is often nonspecific and a high index of suspicion is necessary to make an early diagnosis.

MRI findings in a child with sigmoid sinus thrombosis following mastoiditis.

We describe the MRI features of sigmoid sinus thrombosis following mastoiditis in a 3-year-old girl. The features consisted of increased signal from the sinus on T2-weighted images and absence of flow on MR venography. It is concluded that MRI enabled a timely diagnosis of this life-threatening disease. MRI, as a non-invasive technique that does not use ionizing radiation, should be considered the investigation of first choice, especially in young patients.

Septic cavernous sinus thrombosis following transsphenoidal craniotomy. Case report.

The authors present a case of late-onset cavernous sinus thrombosis in a 74-year-old man who had undergone transsphenoidal craniotomy for a pituitary macroadenoma 9 weeks previously. The patient developed headache, rapidly progressive ophthalmoplegia, and signs of orbital congestion. After 2 days of ineffective broad spectrum antibiotic therapy he underwent a second transsphenoidal craniotomy for abscess drainage. Intraoperative cultures grew 4+ non-hemolytic Streptococcus, 4+ Staphylococcus coagulase negative, and 4+ Haemophilus influenzae. The patient was maintained on intravenous antibiotic therapy for the following 6 weeks, resulting in a complete clinical recovery. To the authors' knowledge, this is the first report of a septic cavernous sinus thrombosis following a transsphenoidal craniotomy.

Dural-pial arteriovenous malformation after sinus thrombosis.

BACKGROUND: We report an unusual case of acquired dural-pial arteriovenous malformation (AVM) following sinus thrombosis. CASE DESCRIPTION: Initial angiography performed in a 39-year-old man showed thrombosis of the superior sagittal sinus (SSS) and the right transverse sinus (TS) but no vascular malformations. Follow-up angiography 29 months later revealed recanalization of the SSS and the TS, retrograde cortical venous drainage which suggested that thrombosis of the sinuses probably propagated into the adjacent parietal cortical veins, and development of a dural-pial AVM at or near the site of thrombi in more than one cortical vein. Complete surgical excision of the lesion was accomplished without neurological deterioration. CONCLUSIONS: The present case suggests the possibility that the pial AVM is not only a congenital condition but also may develop as an acquired lesion.

A case of septic cavernous sinus thrombosis with sequential dynamic angiographic changes. A case report.

A case of intracavernous aneurysm secondary to septic cavernous sinus thrombosis demonstrating sequential dynamic angiographic changes is reported. Serial angiograms of a 32-year-old man with septic cavernous sinus infection revealed a normal study, stenosis, recovery of stenosis, and aneurysmal formation. Superficial temporal-middle cerebral artery anastomosis and internal carotid artery ligation were performed because of progressive ophthalmoplegia. Neurological deficit rapidly disappeared. Anigiographic changes and surgical treatment of septic cavernous sinus thrombosis are discussed.

Superior sagittal sinus thrombosis in steroid-resistant nephrotic syndrome.

An 8(1/2)-year-old-female child with steroid-resistant nephrotic syndrome developed sagittal sinus thrombosis while on pulse therapy with corticosteroids, presenting with recurrent vomiting, headache, and impaired consciousness. The diagnosis was established by cranial computed tomography, magnetic resonance imaging, and magnetic resonance angiography. She gradually recovered without neurologic sequelae while being treated with low-molecular-weight heparin (2 mg/kg/day). Sagittal sinus thrombosis consists of a rare and probably underdiagnosed complication of childhood nephrotic syndrome.

Thalamic stroke secondary to straight sinus thrombosis in a nephrotic child.

A 7-year-old Chinese boy with steroid-resistant nephrotic syndrome developed thalamic stroke secondary to straight sinus thrombosis. He was hospitalized due to status epilepticus and coma. The child recovered after treatment by low-molecular-weight heparin (LMWH) and warfarin. This case highlights the importance of magnetic resonance imaging with venography in the early diagnosis of cerebral sinus thrombosis (CST) in nephrotic children and the effectiveness of anticoagulation therapy in improving the neurological outcome.

[Intracranial venous sinus thrombosis in nephrotic syndrome].

A 3-year old child was admitted for a third relapse of nephrotic syndrome associated with intracranial hypertension related to dural sinus thrombosis (tomodensitometry). The treatment consisted in the association of low dose heparin and fresh frozen plasma. After a 3 year-follow-up, there was no neurologic sequelae, and the nephrotic syndrome was on complete remission. The radiologic features and the management of sinus thrombosis are discussed.

[Dural sinus thrombosis: case report].

We report the case of a 24 year-old pregnant woman, seen at the neurology service by presenting agitation, hallucinations, mental confusion, headache, vision loss, aphasia and seizures. The neuroradiologic exam was compatible with thrombosis in dural sinus and cortical veins. Treatment with abciximab was accomplished and the mechanical lysis of the thrombus was made obtaining restoration of cerebral vein flow. After the procedure, she presented frontal hematoma which was withdrawn surgically. We discuss this infrequent pathology in clinical picture, pathogenesis, image exams and therapeutics.

Cerebral sinus thrombosis as a potential hazard of antifibrinolytic treatment in menorrhagia.

We describe a 42-year-old woman who developed superior sagittal and left transverse sinus thrombosis associated with prolonged epsilon-aminocaproic acid therapy for menorrhagia. This antifibrinolytic agent has been used in women with menorrhagia to promote clotting and reduce blood loss. Although increased risk of thromboembolic disease has been reported during treatment with epsilon-aminocaproic acid, cerebral sinus thrombosis has not been previously described. Careful use of epsilon-aminocaproic acid therapy is recommended.

Septic cavernous sinus thrombosis associated with gingivitis and parapharyngeal abscess.

A 29-year-old previously healthy man died of spread of infection from gingivitis to both parapharyngeal (pharyngomaxillary) spaces and to the cavernous sinus. The diagnosis was delayed because gingival and parapharyngeal sources of cavernous sinus thrombosis were not initially considered, and the ophthalmic congestion was believed at first to represent orbital cellulitis rather than cavernous sinus thrombosis.
