ABSTRACT
The double skull sign (DSS) is a unique image on the outside of the brain that looks like two skulls. Whereas congenital and acquired types of DSS have been reported, the etiology of both of them is calcified hematomas. We encountered a case of a 46-year-old woman with a history of subarachnoid hemorrhage followed by cranioplasty at 43 years old. She developed right hemiparalysis and motor aphasia suddenly. Brain computed tomography and magnetic resonance imaging revealed not only cerebral infarction but also DSS incidentally. After detailed analysis, we concluded that the DSS in this case was not due to calcification of the hematoma but was related to the cranioplasty. In this report, we present an interesting case and discuss etiologies of the development of DSS after cranioplasty.
ABSTRACT
The Withania somnifera, also called Ashwagandha, is available everywhere in the world. We present a rare case of thyrotoxicosis following Ashwagandha administration, specifically painless thyroiditis (PT) in this report. The patient was a 47-year-old previously healthy Japanese man, who started taking Ashwagandha two months before his first visit to our hospital. He visited our hospital for typical thyrotoxicosis symptoms like a sense of fatigue, fever at night, and weight loss followed by diarrhea and headache. Blood tests disclosed thyrotoxicosis. Thyroid ultrasonography showed internal echo heterogeneity and no increase in blood flow. Thyroid scintigraphy revealed a deficiency in thyroid uptake. Based on these findings, he was diagnosed as PT. After stopping the administration of Ashwagandha, both his symptoms and serum thyroid markers were improved. This report may spark important debate about whether ashwagandha is safe among healthy people, especially in thyroid toxicity.
ABSTRACT
Lateral medullary infarction (LMI), or Wallenberg syndrome, can develop various symptoms, but it is rare that ipsilateral axial lateropulsion (or body lateropulsion, BL) or atonic bladder (AB) are caused by LMI. This report describes a case of LMI with both BL and AB. A 77-year-old man, with a history of hypertension and diabetes, developed acute left BL and anuresis. A neurological exam showed right gaze nystagmus, slight dysarthria and dysphagia, right dysesthesia in the trunk, and ataxia in the left limbs and trunk. Horner's syndrome and paralysis were unremarkable. Brain magnetic resonance imaging revealed hyperintensity in the lateral medulla oblongata. Cystometry revealed AB, although the patient had the urge to urinate. Owing to acute therapy, although trunk ataxia was presented for several months, BL and anuresis were recovered on day 15 and day 35, respectively. Here, we describe the potential mechanisms of BL and AB caused by LMI.
