[Neuroradiological pattern of peripartum cerebro vascular disease medicating transfer to determine care unit]

Pregnancy and puerperium are considered a period of a high risk of stroke responsible in a part of the morbidity and mortality in women. Imaging is the pivotal tool to diagnostics and care. To investigate the clinical and imaging features cerebrovascular complications during pregnancy and in post partum period. We report a retrospective analysis of forty four patients [November 2002 - October 2010] admitted in the intensive car department of the national institute of neurology for cerebro-vascular complications during pregnancy and in post partum period. Cerebro-vascular imaging modalities included cerebral computed tomography [CCT] with and without contrast in 94% of cases, magnetic resonance imaging [MRI] in 30.6% of cases completed by venous angiography MRI in 27.2% of cases and angiography MRI of Willis polygon in 11.3% of cases and by cerebral angiography in 13.6% of cases. Posterior reversible encephalopathy syndrome [PRES] is diagnosed in 61.4% of cases followed by meningo-cerebral haemorrhage [MCH] in 29.5% and finally cerebral venous thrombosis [CVT] and arterial ischemia in 4.5% of cases each one. The cerebro-vascular complications are revelled in 86.3% of the cases during the postpartum and were associated with the eclampsia or preeclampsia in 90.9% of the cases [n=40]. CCT showed typical lesions of PRES in 23 patients. It confirms the presence of hematoma in the 13 patients with MCH and find hypodense lesion in one case with ischemic stroke. CCT show direct [delta sign] and indirect signs of CVT. MRI confirms the diagnostic of PRES, when done [11 of 12 cases] and show cortical sub cortical hyper signal on T2 and FLAIR and hypo signal on T1 sequences. MRI was normal in one case. It shows hemorrhagic lesion in the 2 cases of MCH, thrombosis in the cases of CVT and ischemic lesion in the cases of ischemic stroke. CCT and MRI done within 48 hours from admission were decisive for early diagnostic and for fast and adequate care. Early recognition of stroke in peri partum by cerebral imaging is of paramount importance for prompt diagnosis and treatment to improve maternal morbidity and mortality

Hypocalcaemia due to hypoparathyroidism in beta-thalassemia major: a study of a new case

To report a new case of hypoparathyroidism in a child with beta thalassemia major. We report a case of a 17-year-old Tunisian girl with transfusion-dependent thalassemia major presented with paresthesia and pubertal delay. Laboratory investigations showed hypocalcaemia and hyperphosphatemia. Parathyroid hormone level was low [2 ng/1, normal range: 12-72 ng/1] than expected for the degree of hypocalcaemia. Serum ferritin concentration was 1770ng/ml. The patient was started on oral daily calcium supplementation, Alfa calciferol and intensive iron chelation therapy. Follow-up after 6 and 12 months revealed normal Calcium and ECG showed QT intervalwithin normal range. Investigating calcium homeostasis at regular intervals and early management of any abnormality can preclude the occurrence of complications

[Imaging diagnosis of an unilateral painful ophtalmoplegia]

The ophtalmoplegia may be due to several lesions and the diagnosis is made by imaging modalities. We report the case of a giant aneurysm of the right intracavernous internal carotid artery revealed by painful ophtalmoplegia with subarachnoid haemorrhage. The diagnosis was made by magnetic resonance imaging and angiography

liponeurocytome cerebelleux: a propos d'une observation

The cerebellar liponeurocytoma is a rarely and recently described tumour. It may be distinguished on the basis of neuroimaging findings that demonstrate the areas of fat density. Complete surgical removal with postoperative radiation therapy is recommended. It has a relatively more favourable prognosis. We report the case of a 38-year-old woman without particular pathological antecedent with a few months history of headache and dizziness, aggravated since 2 days by signs of increased intracranial pressure and cerebellar dysfunction. The Computerized Tomography practiced in emergency showed a subtentorial space occupying mass, heterogeneous, exhibiting the attenuation values of fatty tissue, with hydrocephalus upstream. The patient has been operated. The histopathological and immunohistochemical studies concluded to a cerebellar liponeurocytoma

[Intradiploic hematoma: report of two cases and review of literature]

Diploic hematoma is an uncommon lesion which develops generally after minor head trauma. Only seven cases have been published so far and we are reporting two new cases of diploic hematoma in infancy. The diagnosis was made by computerized tomography and confirmed by histology. Diploic hematoma should be considered as part of the differential diagnosis in case of with a diploic lesion

cavernome cerebral radio-induit. A propos d'un cas

Recently, there have been several case reports of cavernous angiomas appearing after radiation to the brain, typically in children. The time interval between irradiation and the detection of the cavernous angioma varied from three to nine years and the doses from 24 to 60 grays. We report the appearance of a cavernous malformation in a young girl 3 years after radiation therapy for a brain tumor

Menringocele sacree anterieure associee a une spondylodiscite lombaire. Apport de l'imagerie

Anterior sacral meningocele is a rare congenital anomaly, the authors report one case, association with marked by lumbar spondylodiscitis infectious. The authors emphasize about the role of imaging [US, CT] whose permit in this case to distinguish between this malformation and a collection in relation with the spondylodiscitis
