Thunderclap headache attributed to reversible cerebral vasoconstriction (THARCV) is a syndrome observed in a number of reported cases. In this article we reviewed this new headache entity (idiopathic form) using the clinical-radiological findings of 25 reported patients. In this series of patients 72% were women, the mean age at the onset of first headache episode was 39.4 +/- 2.3 years. In addition to the sine qua non condition of being abrupt and severe (thunderclap) at the onset, the headache was usually described as being explosive, excruciating, or crushing. The feature of pulsatility, accompanied or not by nausea was described by 80% of the patients. Forty percent of the cases manifested vomiting and 24% photophobia. Usually the headache was generalized, and in three cases it was unilateral at least at the onset. In 21 of 25 patients (84%) there was at least one recurrence or a sudden increase in the intensity of the headache. A past history of migraine was present in 52% of the patients. Precipitating factors were identified in 56% of the patients. Sexual intercourse was described by six patients. Of the 25 patients with THARCV syndrome studied, 12 (48%) developed focal neurological signs, transitory ischemic attack (n = 1), or ischemic stroke (n = 11, 44%), and two (8%) of them manifested seizures. The THARCV syndrome is a neurological disturbance perhaps more frequent than expected, preferentially affecting middle aged female migraineurs, and having an unpredictable prognosis, either showing a benign course or leading to stroke.

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cerebrovascular disorder affecting large- and medium-sized arteries, occurring most commonly in young women. Thunderclap headache is the usual primary symptom; seizure is uncommon. During the postpartum period, seizure is a significant concern. The main causes of postpartum seizures are posterior reversible encephalopathy syndrome and cortical venous thrombosis; RCVS-related postpartum seizure is rare. Despite its rarity, its course may be fulminant, resulting in permanent disability or death if the diagnosis is delayed and treatment is not started promptly. We report an unusual case of RCVS presenting as a subarachnoid hemorrhage in a 31-year-old woman admitted for postpartum seizure.
