Pediatric septic thrombosis of intracranial venous sinuses: from diagnosis to discharge. Twenty years of experience. / Trombosis séptica pediátrica de senos venosos intracraneales: del diagnóstico al alta. Veinte años de experiencia.

INTRODUCTION: Septic thrombosis of intracranial venous sinuses (STSV) is a rare and severe complication of cranial infections. MATERIALS AND METHODS: The main objective of this paper is to describe the clinical data, diagnostic procedures, treatment and evolution of a series of cases of STSV. In addition, the current literature is reviewed. Observational retrospective study by review of medical histories (January 1995-December 2016). The data collected were: clinical, analytical, epidemiological, microbiological, radiological, management and follow-up. A descriptive and statistical analysis of the data was done. RESULTS: Twelve children were included (86,832 admissions studied). They have a median age of 4.5 years (range 1-13) with a median time of symptoms of 6 days (range 1-25). At admission, the clinical data were: fever (11/12), vomiting (9/12) and headache (8/12). They also showed bad general status 12/12, 7/12 acute otitis media and 5/12 VI cranial nerve paresis. The lumbar puncture was pathological in 4/12. The most frequently microorganism isolated was Streptococcus sp. Prothrombotic mutations were confirmed on 2/12. Cranial computed tomography allowed diagnosis in 9/12; the magnetic resonance imaging achieves that in 12/12. Previous neurological signs or time to diagnosis did not influence the appearance of other image complications. All received antibiotic treatment, heparin 10/12 and 11/12 surgery. There were no sequels. CONCLUSION: In our series otitis, headache, vomiting and fever were prevalent. Complementary tests allowed the suspect but the definitive diagnosis was obtained by neuroimaging. There were no sequels and the therapies were mainly wide broad-spectrum antibiotics, heparin, and surgical.

Cryptococcal meningoencephalitis presenting as cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) is characterized by its variety of neurological manifestations and difficulty in diagnosis. In subacute cases, the main symptoms are secondary to increased intracranial pressure. This condition is associated with an extensive range of medical disorders, but only 2% are caused by a CNS infection in recent series. We report a 45-year-old patient, with no previous medical history, who developed a syndrome of increased intracranial pressure as the presentation of a cryptococcal meningoencephalitis (CM) complicated with a CVT. The patient was first diagnosed of a CVT, and later on, the VIH infection and the CM diagnosis were made. Despite being treated with anticoagulation, liposomal amphotericin B, and a therapeutic lumbar puncture, the patient continued to deteriorate and suffered a respiratory arrest secondary to the increased intracranial pressure, with subsequent brain death. Cryptococcus is an infrequent cause of CNS infection in developed countries, despite being the most frequent cause of meningits in adults in several countries with high rates of HIV infection. CVT is a very rare complication of CM which can contribute to worsen the increased intracranial pressure and in consequence, its prognosis and outcome. A high level of suspicion is needed for diagnosing CM as the underlying cause of CVT and the subsequent increased intracranial pressure should be managed exhaustively.

A nine-day-old girl with fever. / En ni dager gammel jente med feber.

Nowadays severe illness in neonates is fortunately rare in Norway. However, newborns present with non-specific symptoms, making diagnostics in this age group challenging, and neonatologists need to think broadly in order not to overlook serious illness. We present the case of a nine-day-old who was severely ill when she arrived at hospital. She was born in gestational week 37 after a normal pregnancy. The birth was complicated by shoulder dystocia, rupture of the umbilical cord and fracture of the clavicle. Thereafter she had a normal stay in the maternity ward for three days. At home she appeared healthy and gained weight until she returned to hospital after thirteen hours of poor feeding, irritability and fever. The symptoms turned out to be caused by bacterial meningitis. During the first week of hospitalisation she developed ventriculitis, brain abscesses and sinus vein thrombosis. It was later discovered that she had severely impaired hearing, and thereafter she developed hydrocephalus requiring surgical drainage. The mortality from neonatal bacterial meningitis has dropped from almost 50 % in the 1970s to less than 10 % today, but the morbidity has remained unchanged. It is crucial that clinicians are alert to this diagnosis, as delayed treatment can worsen the prognosis.

Neurobrucellosis and cerebral venous sinus thrombosis: a case report.

OBJECTIVES: To present a case of co-occurrence of neurobrucellosis and cerebral venous sinus thrombosis. METHODS: Case report. CLINICAL PRESENTATION:  We presented 49-year-old Caucasian domicile female-farmer with a history of headache, weakness, and vomiting for a period of three months. Also, she had significant papilledema. We diagnosed rare co-morbidity of neurobrucellosis (confirmed after ELISA-test in serum samples and CSF analysis of pleocytosis/increase in protein/decrease in glucose level) in the setting of cerebral venous thrombosis developed in left sigmoid/left transverse sinus (confirmed after MRV of brain). Favorable outcome was achieved by applying protracted polymicrobial antibiotic therapy and heparin. DISCUSSION: It may be challenging to diagnose neurobrucellosis, especially in patients with atypical presentation and abortive clinical forms. The co-morbidity of neurobrucellosis and cerebral venous sinus thrombosis is uncommon. However, it provides a possibility of brucella-colonization in cerebral venous sinuses as a potential hidden link between them. CONCLUSION: Patients with severe and persistent headache, as well as other neurological symptoms/signs should be considered for neurobrucellosis in endemic, but also in brucella non-endemic regions due to migrations. According to literature survey, this co-occurrence of neurobrucellosis and cerebral venous sinus thrombosis is third one reported from Europe.

Neurobrucellosis and venous sinus thrombosis: an uncommon association.

Brucellosis is a commonly diagnosed zoonosis and neurological involvement is rare. A 30-year-old woman presented with a pulsatile headache that was exacerbated by the Valsalva maneuver and refractory to analgesic therapy. The patient also had nausea, cough, and coryza that evolved over 7 days. The neurological examination was unremarkable. Thrombosis of the lateral and sigmoid sinus and ipsilateral internal jugular vein were diagnosed and anticoagulation therapy was started. Brucella spp was identified in a sample of cerebrospinal fluid (CSF); five months after treatment with rifampicin and doxycycline, CSF was sterile. Cerebral venous thrombosis is a very uncommon sign of brucellosis.

[Cerebral venous thrombosis during tuberculous meningoencephalitis]. / Thromboses veineuses cérébrales au cours de la méningo-encéphalite tuberculeuse.

Cerebral venous thrombosis is a rare disease characterized by its clinical polymorphism and multiplicity of risk factors. Infections represent less than 10% of etiologies. Tuberculosis is not a common etiology, only a few observations are published in the literature. Between January 2005 and March 2015, 61 patients were hospitalized for neuro-meningeal tuberculosis. Among them, three young women had presented one or more cerebral venous sinus thromboses. No clinical feature was observed in these patients; vascular localizations were varied: sagittal sinus (2 cases), lateral sinus (2 cases) and transverse sinus (1 case). With anticoagulant and antituberculosis drugs, the outcome was favorable in all cases. During neuro-meningeal tuberculosis, the existence of consciousness disorders or neurological focal signs is not always the translation of encephalitis, hydrocephalus, tuberculoma or ischemic stroke; cerebral venous sinus thrombosis may be the cause and therefore should be sought.

Actinomycotic mastoiditis complicated by sigmoid sinus thrombosis and labyrinthine fistula.

Actinomyces is a rare pathogen that can be the cause of infections in the digestive and urinary tracts, skin, genitalia, and lungs, which generally have an indolent clinical course. However, in some cases these can be locally destructive and become generalized infections. Actinomyces has been previously implicated in infections of the middle ear, nasopharynx, and sinuses, occasionally causing complications such as chronic mastoiditis. Here we describe the case of a 10-year-old-male presenting with nausea, vomiting, and headache who developed intracranial complications of actinomycotic mastoiditis.

A rare presentation of cerebral venous sinus thrombosis associated with tubercular meningitis.

Central nervous system (CNS) tuberculosis may manifest as meningitis, meningoencephalitis, tuberculoma, tubercular abscess, stroke due to tuberculous vasculitis and tuberculous encephalopathy. Occasionally, tubercular meningitis (TBM) can predispose to cerebral venous sinus thrombosis (CVST). We report a young man, who developed CVST as a complication of TBM. Worsening of pre-existing headache, impairment of consciousness and seizures should raise suspicion of CVST in any patient with CNS infection. Early diagnosis and appropriate clinical management are important for good outcome.

Rare but numerous serious complications of acute otitis media in a young child.

Acute otitis media is a very common disease in children. Most children recover with symptomatic therapy like potent analgesics, but occasionally serious complications occur. We present a 3-year-old girl who suffered from acute otitis media for already 2 weeks and presented with fever, abducens nerve palsy of her left eye and vomiting. She was finally diagnosed with an acute otitis media complicated by a mastoiditis, sinus thrombosis, meningitis and cerebellar empyema. Fusobacterium necrophorum was cultured from cerebrospinal fluid. The girl recovered following appropriate antibiotic and anticoagulation treatment.

Decisions regarding intracranial complications from acute mastoiditis in children.

PURPOSE OF REVIEW: To review the clinical findings and treatment algorithms for intracranial complications of acute mastoiditis, such as sigmoid sinus thrombosis, otitic hydrocephalus, intracranial abscess, and otitic meningitis. We also briefly discuss the clinical sequelae of these complications. RECENT FINDINGS: Recent changes in the microbiology and treatment paradigms of otitis media have the potential to influence the rates of intracranial complications of mastoiditis; however, evidence supporting a resultant increase in the rates of these complications is lacking. SUMMARY: Antibiotic therapy and myringotomy with ventilation tube placement, with or without mastoidectomy, are the mainstays of treatment for intracranial complications of acute mastoiditis. Adjunct treatment, such as anticoagulation for sigmoid sinus thrombosis, is often used; however, the rarity of these complications makes establishing appropriate levels of evidence to support their use difficult.

Infection related cerebral venous thrombosis.

The incidence of cerebral venous thrombosis (CVT) has dropped dramatically in recent years. In the past, before the introduction of antibiotics, infection was the main cause of CVT. But this is no longer true. Recently, the occurance of septic CVT is rare, which leads to an increased chance of misdiagnosis and treatment delay. Early suspicion and recognition is very crucial to improve mortality and morbidity rates of this potentially fatal disease. Intravenous, wide spectrum, antibiotics and early surgical drainage of the primary site of infection whenever possible are essential. Anticoagulation with intravenous heparin infusion and corticosteroids use are of uncertain benefit, although some reports have shown some favorable response.

The changing face of lateral sinus thrombosis.

Lateral sinus thrombosis is a life threatening complication of middle ear disease, the presentation, diagnosis and management of which has seen many changes in recent times. While the introduction of antibiotics has been associated with a reduction in the incidence and associated morbidity/mortality of this complication, their use has also altered the clinical features of presentation, consequently diagnosis requires a high index of suspicion. Radiological advances, in particular magnetic resonance imaging and magnetic resonance venography, have improved our ability to diagnose this complication pre-operatively, and now are the diagnostic investigations of choice. Intraoperative sigmoid sinus exploration and removal of all necrotic clot are essential steps of surgical management together with appropriate antimicrobial treatment, however the role of anticoagulation therapy remains controversial. We present four recent cases of sigmoid sinus thrombosis and discuss the clinical presentation, investigation and management of this disease.

[Rhinocerebral mucormycosis]. / Une mucormycose rhinocérébrale.

INTRODUCTION: Mucormycosis is a rare and acute fungal infection which is frequently lethal. The rhinocerebral form is usually seen in diabetics, but other localizations may occur in severely immunocompromised subjects. OBSERVATION: We report the case of a sphenoidal sinusitis associated with a probable cavernous sinus thrombosis and carotid artery thrombosis with middle cerebral artery territory infarction. Diagnosis was made on histological examination following sphenoidotomy. Early medical and surgical treatment led to a good outcome. CONCLUSION: The diagnosis of rhinocerebral mucormycosis should be considered in the clinical setting of necrotic sinusitis and acute neurologic deficit in diabetic patients. Early diagnosis and treatment are crucial factors leading to a good outcome.

Natural history of sigmoid sinus thrombosis.

To demonstrate the evolution of sigmoid sinus thrombosis, we performed a prospective observational study on a 6-year-old girl who presented with mastoiditis, epidural abscess, and occipital osteomyelitis from multiple drug-resistant Streptococcus pneumoniae. She underwent mastoidectomy and partial occipital craniectomy. This procedure produced a window in the occipital bone that allowed serial ultrasonography of the sigmoid sinus during medical treatment. Computed tomography was performed, followed by weekly Doppler ultrasonography used to monitor resolution of sigmoid sinus thrombosis. The natural history of a treated episode of sigmoid sinus thrombosis was illustrated. Venous occlusion resolved over a 4- to 6-week period without surgical drainage or venous anticoagulants. Collateral flow, reversal of normal venous flow, and ultimate return to normal venous transport characterized the period of resolution. We conclude that an occluded sigmoid sinus from mastoiditis can naturally recanalize. Aberrant venous flow can be demonstrated during the period of resolution. This case supports a conservative approach to management of the occluded sinus and suggests that 4 to 6 weeks of antibiotic therapy after removal of perisinus infection is sufficient for cure.

[Non-infectious thrombosis of the cerebral venous sinuses and veins in adults. A report of five cases]. / Trombosis no infecciosa de los senos y venas cerebrales en adultos. Presentación de cinco casos.

INTRODUCTION: Thrombosis of the veins and venous sinuses is an uncommon condition. In 1947 it was described in adults by Garcin and Pestel. It is a potentially serious disorder, in which there is severe intracranial hypertension which may be fatal or cause serious neurological sequelae. Diagnosis is made, during life, on the clinical condition and neuro-imaging features. We consider that treatment of the underlying condition is essential to improve prognosis, although this is controversial. In Cuba there are no publications reporting series of patients with this condition. CLINICAL CASES: We present five patients, four of whom were women, with a neurological disorder involving focal neurological deficits, headache and severe intracranial hypertension, of subacute onset and with convulsions in 60%. The results of imaging studies were compatible with thrombosis of veins and/or venous sinuses. The diagnosis was conformed at necropsy in two patients. The commonest risk factor was the puerperium, occurring in four cases. The patients were treated symptomatically. Two patients died. The other patients made good progress. CONCLUSIONS: The puerperium is the commonest risk factor in thrombosis of the venous sinuses and the veins draining into them. Headache, neurological focal signs and level of consciousness are the main symptoms and signs. Coma, haemorrhagic infarct and convulsions are of bad prognosis and followed by unsatisfactory progress of the disorder.

Invasive aspergillosis presenting as a cavernous sinus mass in immuno competent individuals; report of 3 cases.

Aspergillosis of the cavernous sinus is rare, especially in immuno competent individuals. We report three such cases secondary to paranasal sinus aspergillosis, with imaging findings.
