Imaging Features and Pathological Correlation in Mixed Microcystic and Angiomatous Meningioma:A Case Report

Meningiomas are the most common intracranial tumors. However, microcystic and angiomatous meningiomas are very rare subtypes that present unusual imaging findings. Hence, radiological diagnosis of these tumors can be challenging. We herein describe a case of mixed angiomatous and microcystic meningioma in an 81-year-old male. MRI revealed an extra-axial mass with high T2 signal intensity, measuring 1.5 cm in diameter, with multiple tiny intralesional cysts and entrapped peritumoral cyst formation. After tumor resection, a histopathological diagnosis of mixed angiomatous and microcystic meningioma was made.

Paraplegia in a Patient With IgG4-Related Sclerosing Disease: A Case Report

Immunoglobulin G4 (IgG4)-related sclerosing disease is a systemic disease, characterized by mass forming inflammatory lesions which respond well to steroid therapy. Pancreas is the most common site of involvement, and other organ involvements are also common. However, there are only a few reports about central nervous system involvement. We report a case of IgG4-related sclerosing disease which involves spinal cord causing paraplegia. A middle-aged female presented with sudden lower limb weakness. Magnetic resonance imaging showed a soft tissue mass which was diffusely compressing spinal cord along the C7 to T5 levels. Intravenous steroid pulse therapy and emergent operation was performed. The immunopathologic findings revealed IgG4-related sclerosing pachymeningitis postoperatively. There was no evidence of other organ involvement. Her neurologic deficit remained unchanged after two months of comprehensive rehabilitation therapy.

Chelidonium majus-Induced Acute Hepatitis / 이화의대지

The use of traditional folk remedies is increasing throughout Asia. Chelidonium majus, a popular herbal remedy, is used to treat abdominal pain caused by various gastrointestinal disorders, including gastric ulcer, gastritis, and biliary tract disease, because of its morphine-like effect. We encountered a 62-year-old woman with acute hepatitis, in which C. majus was suspected to be the etiological factor. The patient had taken high dose of C. majus extract for the preceding 60 days. The clinical context and the temporal association between the start of the herbal medicine treatment and her liver injury allowed us to attribute a causative role to C. majus. The diagnosis was confirmed by liver biopsy and the Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale. After C. majus was discontinued, the liver function was restored to normal. In conclusion, because the use of phytotherapy is increasing, we wish to raise awareness of the potential adverse effects of C. majus.

A case of omental pregnancy / 대한산부인과학회지

Abdominal pregnancy is a rare variation of ectopic pregnancy, which has been classified as primary or secondary. The clinical characteristics of abdominal pregnancy are extremely variable, so early diagnosis is very difficult. Because of high maternal morbidity and mortality, the prompt surgical intervention is required. Omental pregnancy is a very rare form of abdominal pregnancy, which is hard to detect early. The diagnosis of omental pregnancy is hardly ever made prior to laparotomy. We have experienced a case of omental pregnancy in a 36-year-old woman and report this case with brief review of literature.

A Case of Lipoleiomyoma / 대한산부인과학회잡지

Uterine lipoleiomyoma are rare benign tumors consisting of smooth muscle and mature adipose tissue. Because of their rarity, fat content, and variable gross morphology, they may be mistaken on radiodiagnosis for the much more common benign cystic ovarian teratoma. The key to differentiate these lesions is the identification of the organ of origin. A mass that arises from the uterus is most likely a lipomatous uterine tumors. Because malignant degeneration occurs in 1-2% of benign cystic ovarian teratomas, their differentiation can be clinically significant. While these tumors are treated by surgical excision, asymptomatic lipomatous uterine tumors and benign pelvic lipomas may require no therapy. The fatty nature of the lipoleiomyoma was demonstrated with standard spin-echo Magnetic resonance imaging (MRI) and further supported using fat- suprressed inversion recovery MRI. MRI also clearly depicted the intrauterine location of the tumor. We report a case in which a preoperative diagnosis of a uterine lipoleiomyoma was made with MRI and fat suppressed MRI.

Giant Cell Tumor of the Larynx: Report of a case

Giant cell tumor arising in the osteocartilaginous tissue of the larynx is extremely rare. The few reported cases have all occurred in men older than 20 years and the site of origin has been exclusively localized to the thyroid and cricoid cartilages that are known to undergo enchondral ossification. The formation of giant cell tumor in larynx is thought to be related to this enchondral ossification process. We report a case of giant cell tumor arising in the thyroid cartilage of a 39 year old man. CT scan of the neck revealed a well defined mass of soft tissue density replacing the right thyroid cartilage. Grossly the tumor was well demarcated with a distinctive pushing margin except for the area bordering the submucosa of the larynx where it showed focally an infiltrative pattern of growth. Microscopically multinucleated giant cells were found dispersed regularly among the spindle cells. Although mitoses were frequently noted in the spindle cells there was no atypicality or pleomorphism. Total laryngectomy was performed without further treatment. Postoperative follow up for 6 months has proved the patient to be alive and well without recurrence.
