We describe a 44-year-old woman with paresthesia, fatigue, and palpitation, 10 days after human papillomavirus (HPV) vaccination. The quantitative sensory test showed abnormal detection threshold in her foot. Tilt test result indicated postural orthostatic tachycardia syndrome. Symptoms were improved after immunomodulating therapy, pain control drug, and oral beta blocker medication. This is first case report for small fiber neuropathy and autonomic dysfunction after HPV vaccination in Korea.

Neovascular glaucoma is a subtype of secondary glaucoma that is characterized by proliferation of fibrovascular tissue in the anterior chamber angle. This condition may be acutely aggravated by carotid revascularization therapies. There have been few previous reports of acute aggravation of neovascular glaucoma following carotid artery stenting. We report the case history of a patient who had acute exacerbation of neovascular glaucoma following carotid artery stenting and required surgical management.

Cerebellar Hippocampal and Basal Nuclei Transient Edema with Restricted diffusion (CHANTER) syndrome is characterized by an altered mental status. The acute MRI lesions show abnormal restricted diffusion imaging bilaterally and symmetrically in the cerebellum, hippocampus, and basal nuclei. This syndrome is an unknown syndrome and is presumed to be mainly an opioidinduced toxidrome. Here, we present a case study wherein we show that it can also be caused by an antidepressant overdose.

The prognosis for pancreatic cancer patient is very poor. Patients with locally advanced disease have a median survival time of 8 to 12 months, and patients with distant metastases have significantly worse outcomes, with a median survival time of only 3 to 6 months. Approximately 30% of patients with pancreatic cancer present with locally advanced disease defined as unresectable pancreatic cancer without evidence of distant metastatic disease. Primary treatment options in locally advanced pancreatic cancer include chemotherapy and radiotherapy. Here, we reported a patient with locally advanced pancreatic cancer who does not want further chemotherapy because of chemotherapy induced nausea and vomiting. Irreversible electroporation was performed. Irreversible electroporation was well tolerated in this case, and may be a therapeutic modality for selected patients with locally advanced pancreatic cancer.

Intussusception and acute appendicitis are common emergency conditions in children. They should be promptly differentiated in pediatric patients presenting with suggestive symptoms. However, both diseases may occur simultaneously. Herein, we present two cases of intussusception of the appendix accompanied with appendicitis.

Renomedullary interstitial cell tumors are often incidentally identified either upon autopsy or kidney resection for other reasons. However, rare renomedullary interstitial cell tumor cases resulting in a clinical symptomatic mass have been reported. We present a case of renomedullary interstitial cell tumor that was manifested as an incidentally detected renal mass and mimicked renal cell carcinoma on the imaging features.

Acinic cell carcinoma is a rare malignant tumor that accounts for 2%-3% of salivary gland tumors. Acinic cell carcinoma arising from the breast is extremely rare, with only approximately 70 cases reported to date. Owing to its rarity, previous studies have primarily focused on pathological findings. Herein, we present the clinical and radiological features of acinic cell carcinoma of the breast in a 33-year-old woman.

Clear cell borderline ovarian tumor (CCBOT) is quite rare, and only a few cases of CCBOT have been reported. Unlike most borderline ovarian tumors, CCBOTs appear solid because they are almost always pathologically adenofibromatous. Herein, we report the MRI findings of a CCBOT discovered in a 22-year-old female.

A 52-year-old male complained of a painless, firm, and slow-growing mass in his right breast outer portion. The chest CT revealed a 3.3 cm-sized oval shaped, microlobulated, mild enhancing mass. Ultrasound showed a microlobulated marginated heterogeneous hypoechoic mass with internal vascularity and calcifications in the mass. On the ultrasound-guided core needle biopsy, the mass was confirmed as a benign granular cell tumor (GCT). The patient transferred to another hospital and underwent surgical removal of the lesion. GCT of the breast is uncommon and mostly benign neoplasm to originate from Schwann cell. Clinical and radiologic features of GCTs, including CT and ultrasound images, mimic malignancy and make diagnosis of GCT more difficult. The CT images of GCTs are much rarely reported. Physicians and radiologists must be aware of radiologic characteristics of this rare benign tumor for male breast, to avoid misdiagnosis this tumor for breast malignancy and overtreat.

Transient isoniazid-induced brain lesions have rarely been reported. The lesions were in the dentate nucleus of cerebellum and thalamus. Meanwhile, the neurotoxicity of rifampin has not been reported evidently. We observed bilateral lesions in the internal capsule in a young woman after taking a combination of isoniazid and rifampin. She transiently suffered numbness in both hands, dysarthria, and left side motor weakness while taking the medication. Isoniazid may induce structural lesions in various brain areas including the internal capsule.
