    Abstract Background: Reversible cerebrovascular constriction syndrome (RCVS) presents with thunderclap headache and ischemic neurological deficits due to focal vasoconstrictions in major intracranial arteries. Reversibility of focal vasoconstrictions is the hallmark of RCVS. The commonest conditions associated with RCVS are a post-partum state and administration of vasoactive agents.
    Methods: We describe a series of 3 cases of thrombotic thrombocytopenic purpura (TTP) who presented with thunderclap headache and focal neurological deficits.
    Results: Vascular imaging revealed focal areas of constrictions in multiple intracranial arteries. All cases were treated with plasmapheresis and serial transcranial Doppler (TCD) and magnetic resonance angiography revealed resolution of cerebral vasoconstriction, accompanied by clinical recovery.
    Conclusion: RCVS should be considered in patients with TTP who presented with thunderclap headache. TCD is an important tool for monitoring the course of cerebral vasoconstriction in TTP.

    Abstract Isolated cortical vein thrombosis is an uncommon condition and often difficult to diagnose, both clinically and radiologically. We report a case of a 38 years old man who presented with headache of new onset and clinical examination was unremarkable. The unenhanced brain CT did not reveal any abnormality. In view of unrelenting headache and partial seizures, we performed magnetic resonance imaging (with axial T1, T2 and gradient echo sequences, coronal FLAIR, diffusion weighted imaging as well as Gadolinium contrast-enhanced images) and magnetic resonance venography of the brain that revealed an isolated parietal cortical vein thrombosis with the rarely reported 'cord sign'. We report the clinical and radiological findings in our patient with isolated parietal cortical vein thrombosis.

    Abstract Background: Transcranial Doppler (TCD) is reliable and reproducible for the diagnosis of right-to-left cardiac shunts (RLS).
    Methods: Various factors limiting the performance and diagnostic methods of RLS by TCD are discussed.
    Results: In patients with insufficient temporal acoustic windows, TCD may still be reliably used to monitor the microembolic signals at various alternative sites. Diagnostic yield of TCD may be further improved and better quantitative assessment of the 'functional potential' of the RLS by optimizing the preparation of the 'air-saline-blood' contrast-mixture, injecting the mixture in controlled body positions and using power M-mode TCD.
    Conclusions: TCD may be used reliably for the detection as well as the quantification of RLS even in patients with insufficient temporal acoustic windows.
