[18]F-FDG PET/CT in the diagnosis of tumor thrombus from anaplstic thyroid carcinoma in a young boy

Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid. PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increased FDG uptake, thus pointing toward tumor thrombus. To our knowledge, this is the first case wherein the PET/CT diagnosis of tumor thrombosis from anaplastic thyroid carcinoma was made in a young patient

Unusual diagnosis of Von Hippel Lindau syndrome on PET/CT - Case report and brief review of literature

We report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose PET/CT scans revealed a constellation of findings that suggested the rare Von Hippel Lindau syndrome. The diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography [CECT] and contrast enhanced magnetic resonance imaging [CEMR]. The report highlights the need to carefully evaluate subtle findings on PET/CT that could be missed or misinterpreted as other diagnoses. It also adds to the existing literature of two cases with Von Hippel Lindau syndrome and medullary carcinoma of thyroid

Anatomical study on true hermaphroditism in an Indian pig (Sus Scrofa Domesticus)

A pig was confirmed to be a true hermaphrodite on the basis of gross and histomorphological studies of the genital organs. The genitalia was consisted of left ovary, oviduct, two coiled uterine horns, body of uterus alongwith right testis and an epididymis. Vagina and vulva were absent but male urethra with prostate gland was present. Grossly the size of all the genital organs appeared to be normal. Histomorphologically, testis and epididymis were underdeveloped as there was no clearcut spermatogenia and sertoli cells but Leydig cells were normal. The ovary presents normal histological features with some portion of testicular tissue. Degeneration of uterine epithelium was observed along with normal endometrial glands.
