Most eukaryotic parasites are obligately heteroxenous, requiring sequential infection of different host species in order to survive. Toxoplasma gondii is a rare exception to this rule, having a uniquely facultative heteroxenous life cycle. To understand the origins of this phenomenon, we compared development and stress responses in T. gondii to those of its its obligately heteroxenous relative, Hammondia hammondi and have identified multiple H. hammondi growth states that are distinct from those in T. gondii...

We present a solution to meet an unmet clinical need of an in-situ "close look" at a pulmonary nodule or at the margins of a pulmonary cyst revealed by a primary (screening) chest CT while the patient is still in the scanner. We first evaluated options available on current whole-body CT scanners for high resolution screening scans, including ROI reconstruction of the primary scan data and HRCT, but found them to have insufficient SNR in lung tissue or discontinuous slice coverage. Within the capabilities of current clinical CT systems, we opted for the solution of a secondary, volume-of-interest (VOI) protocol where the radiation dose is focused into a short-beam axial scan at the z position of interest, combined with a small-FOV reconstruction at the xy position of interest...

We investigated the radiologic-pathologic correlation of a strong hypointense rim on T2-weighted images (T2-hypo-rim) surrounding breast mass lesions and evaluated its clinical significance. We retrospectively reviewed 3503 consecutive breast magnetic resonance imaging (MRI) examinations. The T2-hypo-rim was defined as a border of strong hypointensity compared with the fat signal on fat-suppressed T2-weighted images. Detected lesions with T2-hypo-rim were classified as a solid or cystic mass with MRI and correlated with histopathologic findings...

PURPOSE: The management of hydatid disease (HD) co-occurring with pregnancy remains a challenge for physicians. We aimed to determine factors that were related to fetal and maternal outcomes in HD complicated pregnancies and then develop an approach/treatment algorithm. METHOD: All patients at the participating hospitals were first analyzed to determine whether they had HD. Only patients diagnosed with HD during the course of their pregnancy were included. Certain cyst-related factors (diameter, localization, increase in size, and viability) and certain pregnancy-related factors (treatments, gestational week, maternal co-morbidities, and delivery type) were investigated...

In Thalassodrilides cf. briani, the paired ovaries are inconspicuous and polarized structures with developmental gradient of germ cells along their long axis. The about 300 germ cells in the ovary are consolidated into one syncytial cyst and each cell is connected to a common and branched mass of cytoplasm via one stable cytoplasmic bridge. The germ cells differentiate their fate into nurse cells and oocytes. Only one oocyte grows in a given time; it gathers cell organelles and yolk and then it detaches from the gonad...

Cardiovascular disease is the leading cause of sudden death in the world. The etiology of sudden cardiac death involves a wide range of diseases, but seldom pericardial cysts. A pericardial cyst is an uncommon cyst usually located in the middle mediastinum and rarely in the posterior part. They are usually harmless and asymptomatic. Here, we present a case of a 63-year-old woman who presented with dyspnea and hoarseness, but died suddenly after a CT scan was attempted. The detailed forensic pathologic and histologic examination revealed a pericardial cyst located in the posterior mediastinum...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

A 20-month-old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6-week history of toe-touching to nonweight-bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid...

Vulvovaginal cysts are a common problem for women, causing significant pain, discomfort and impact on quality of life. For clinicians, classifying and differentiating these cysts from each other and selecting appropriate management can be challenging, yet there is no integrated classification system and little literature that broadly summarises a clinical approach. We aimed to create a useful tool for clinicians by providing a detailed summary of various vulvovaginal cysts and abscesses with a clear novel classification system and hierarchy for diagnosis and management, to aid clinicians in this process...

Purpose: To report a rescue technique for complete removal of an accidentally ruptured orbital dumbbell deep dermoid cyst. Observations: A 33-year-old female presented with left proptosis with retrobulbar discomfort for 3 months. Computed tomography images showed an orbital dumbbell deep dermoid cyst. A lateral orbitotomy was performed under general anesthesia. The cyst was ruptured during osteotomy of the lateral orbital rim. The cyst was opened vertically from the ruptured site using a Stephen's tenotomy scissors to visually confirm the internal wall of the cyst and to keep the epithelial lining intact while separating the external wall of the cyst from the bone...

Adenoid cystic carcinoma of the Bartholin Gland (BG-ACC) is a rare form of vulval cancer with only approximately 350 reported cases since 1864. A review of available literature and case reports suggests an aggressive nature with protracted clinical symptoms and a tendency for local recurrence despite adequate surgical excision with or without adjuvant radiotherapy. Survival rates of 71% and 59% are reported at five and ten years. This case report endeavours to add to our body of knowledge regarding this rare disease and thus help broaden and improve our understanding of management and treatment success...

A 43-year-old man was operated on for right frontal oligoastrocytoma. 14 years after the surgery, magnetic resonance imaging and positron emission tomography revealed a new lesion near the surgical cavity. He underwent gross total resection of the lesion and implantation of bis-chloroethylnitrosourea (BCNU) wafers after intraoperative pathological diagnosis of recurrent high-grade glioma. A few days after the operation, the level of consciousness gradually worsened and left hemiparesis developed. A computed tomography scan revealed a cyst remote to the surgical cavity which did not exist 3 days prior...
