A 10-year-old Saudi girl was referred from a local hospital with right side weakness, which was of sudden onset, started in the right lower limb, and 2 days later involved the right upper limb. She had a history of 4 months of pallor, and 2 weeks skin bruising prior to the onset. It was not associated with facial weakness, headache, fever, convulsion, visual disturbance, or loss of consciousness, and no history of preceding head trauma. She had a similar attack of left side weakness 5 months earlier, which resolved spontaneously without medical evaluation at a local hospital. Her mother noticed that she is shorter than her other siblings. Her immunization was completed, and her physical, and cognitive development was normal. Her parents were first degree cousin, and had 6 other siblings. Her physical examination revealed a well looking girl, with pallor and skin bruising on lower limbs, with 2x3cm scattered café au lait spots on the back, and inguinal region. Her weight was 25 kg, below 5th centile for her age, and her height was 118 cm, below the 3rd centile for her age. She had right hemiparesis, there were no hepatosplenomegaly, and the examination of other systems were unremarkable.\nHer investigations showed white blood cell count 2600/mm3 (normal value [NV] - 4000-10500/mm3), neutrophil count 500/mm3 (NV - 3000-5000/mm3), hemoglobin 6.3 g/dl (NV - 12.5-16.1 g/dl), and platelet count 33000/mm3 (NV - 150-400/mm3). Her liver and renal profile were within normal limits. Bone marrow aspiration showed hypocellular marrow. Chromosomal analysis confirmed chromosomal breakage. Brain MRI showed a left frontal focal area of acute ischemic infarction, and an area of right parietal periventricular white matter old infarction, with multiple small white matter lacunar infarcts (). The brain MRA showed poor arterial circulation, and a narrow distal internal carotid artery with puff of smoke sign (arrow) on the right side suggestive of moyamoya disease (). The diagnosis was confirmed as FA, with association of moyamoya disease, presenting with right hemiplegia. She was managed initially by supportive care in the form of a blood transfusion, and physical therapy for hemiplegia, later she underwent partial match related donor stem cell transplantation (SCT), but unfortunately, she died after 3 months from post SCT complications.
A 36 year old African American female presented to the Out Patient Office with headache which was on and off for last 4–6 months. The headache presented was of piercing type with moderate intensity not relieved by butalbital, acetaminophen. It was associated with weakness on right hand side for last few days, which evolved into dizziness and speech difficulty. There was no associated fever, night sweats, loss of consciousness, vomiting, ataxia, photophobia, tingling, numbness, difficulty swallowing, difficulty hearing, neck stiffness, vision problems. Her family history was significant for hypertension, diabetes and coronary artery disease. General physical examination showed no abnormalities. She is obese with BMI of 36.4; Vitals include [Heart Rate = 93/min, Blood Pressure = 165/75 mm Hg, Temp. = 36.67°C, Resp. Rate = 18/min]. Neurological examination showed intact 2–12 cranial nerve function, motor strength grossly intact with strength 3/5 on the right side of hand. No pronator drift, normal muscular tone, and gait was normal. Laboratory investigations, complete blood count, electroencephalogram and echocardiogram were normal.\nA CT angiogram head with contrast shows one sagittal [\n] and two axial views [\n,\n] at the level of the lateral ventricle and Circle of Willis, demonstrate mild proliferation of collateral vessels emanating from the distal internal carotid artery particularly on the left side. In addition, the visualized portion of the distal internal carotid artery and M1 segment of the left middle cerebral arteries appeared somewhat diminutive in caliber. Findings were generally compatible with progressive vascular occlusive process which can be seen in Moyamoya disease.\nSince the patient was refractory to the pain medications, surgical revascularization was done and the procedure involved left superficial temporal artery-left middle cerebral artery bypass without any complications. Following surgery, she was prescribed 81mg aspirin and discharged home and was followed up initially after surgery once every three months for one year followed by every 6 months for next four years. She did not complain of any headaches or focal neurological symptoms.
