Neck masses in children can be inflammatory, congenital or neoplastic. When a congenital cyst becomes infected repeatedly, it may mimic inflammatory disease and the diagnosis may be challenging with ultrasound. An increasing incidence of infection with non-tuberculous mycobacterial organisms has been observed in recent decades in children with cervical lymphadenopathy. An ultrasound scan performed during the infectious phase of a mass can be misleading and can lead to an incorrect diagnostic hypothesis with the risk of erroneous medical and surgical therapies...

OBJECTIVE: Patients presenting with cystic lesions in the neck without obvious signs of malignancy constitute a diagnostic challenge since fine needle aspiration is often insufficient and a diagnosis may not be reached until surgical resection/biopsy is performed. The differential diagnosis of a cystic cervical mass comprises a variety of benign conditions, but malignancy must be ruled out. We examined the diagnostic performance of fluorine-18 fluorodeoxyglucose ((18)F-FDG) PET/CT to identify malignancy...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease in Western countries. The prevalence is between 2.4/10,000 and 3.9/10,000. ADPKD represents a systemic disease resulting in deterioration in renal function. Until now, mutations in two genes (PKD1 and PKD2) have been identified. Recently, the European Medicines Agency (EMA) approved the use of the vasopressin V2 receptor antagonist tolvaptan to slow the progression of cyst development and renal insufficiency connected with ADPKD in adult patients with chronic kidney disease stages 1-3 at initiation of treatment with evidence of rapidly progressing disease...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic hereditary kidney disease characterized by progressive enlargement of renal cysts. The incidence is 1-2‰ worldwide. Mutations in two genes (PKD1 and PKD2) cause ADPKD. Currently, there is no pharmaceutical treatment available for ADPKD patients in China. Summary: This review focused on advances in clinical manifestation, gene diagnosis, risk factors, and management of ADPKD in China. There is an age-dependent increase in total kidney volume (TKV) and decrease in renal function in Chinese ADPKD patients...

BACKGROUND: Ventricular tumors represent a major neurosurgical challenge, making endoscopic approach an invaluable tool as it gained importance due to technological advances. Nevertheless, the method is not exempt of risk and limitations, sometimes requiring an open surgery. Thus, initial measurements must be adopted in order to simplify an eventual need for conversion to open craniotomy. METHODS: Here, we describe a series of 6 patients with ventricular tumors approached by neuroendoscopy where the conversion to microsurgery turned out to be necessary...

Developmental anomalies of the urogenital tract are rare but often encountered. Zinner's syndrome is a rare congenital abnormality of mesonephric (Wolffian) duct consisting of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction due to developmental arrest in early embryogenesis affecting the caudal end of Mullerian duct and only approximately a 100 cases have been reported so far. Radiologic modalities such as intravenous pyelography, ultrasonography, vasovesiculography, contrast enhanced computed tomography, and magnetic resonance imaging are all helpful in diagnosis of this unusual entity...

Splenic tumors are not frequent. Blood vessel neoplasms are a rare category of tumors and have an extremely low incidence in the spleen. This case report aims to describe a 57-year-old woman in whom a routine imaging examination had shown splenic cysts. During her follow-up, the cysts became larger and increased in number. A diagnostic splenectomy was performed and its analysis showed a rare splenic angiosarcoma.

Haemoperitoneum in women of reproductive age usually suggests either ruptured ectopic pregnancy or ruptured ovarian cysts. Metastatic choriocarcinoma is considered the least common cause of haemoperitoneum in women of childbearing age. We report a rare case of pancreatic and hepatic metastasis of choriocarcinoma in a young, 30-year-old female who had delivered 10 months prior at term gestation with no previous history of gestational trophoblastic disease or molar pregnancy. She had a short history of fever and pain in the right hypochondrium, with findings of hypovolaemic shock due to intraperitoneal haemorrhage...

BACKGROUND: In mammalian females, reproductive capacity is determined by the size of the primordial follicle pool. During embryogenesis, oogonia divide mitotically but cytokinesis is incomplete so oogonia remain connected in germ cell cysts. Oogonia begin to enter meiosis at 13.5 days postcoitum in the mouse and over several days, oocytes progress through the stages of meiotic prophase I arresting in the diplotene stage. Concurrently, germ cell cysts break apart and individual oocytes become surrounded by granulosa cells forming primordial follicles...

Tailgut cysts are rare benign retrorectal cysts arising from persistent remnants of an embryonic hindgut. Malignant transformation inside this lesion is very uncommon and occurrence of neuroendocrine tumours in this context is extremely rare. We report the case of a 56-year-old woman who underwent surgical excision of a presacral tailgut cyst, which was found incidentally to include a neuroendocrine tumour.

Aquaporin-11 (AQP11) is an intracellular water channel expressed at the endoplasmic reticulum (ER) of the proximal tubule. Its gene disruption in mice leads to intracellular vacuole formation at one week and the subsequent development of polycystic kidneys by three weeks. As the damaged proximal tubular cells with intracellular vacuoles form cysts later, we postulated that autophagy may play a role in the cyst formation and examined autophagy activity before and after cyst development in AQP11(-/-) kidneys...

BACKGROUND: Foregut duplication cysts are rare congenital anomalies that require surgical intervention with approximately 10%-15% of all gastrointestinal duplication cysts originating from the esophagus. Consensus is lacking among surgeons regarding closure of the esophageal muscle layer after resection of an esophageal duplication cyst and long-term outcomes are poorly documented. Therefore, we conducted the first study comparing complication rates in patients undergoing closure versus nonclosure of the esophageal muscle layer after esophageal duplication cyst resection...

Sylvian arachnoid cysts pose considerable management dilemmas. Surgical options include cyst fenestration, either endoscopically or microsurgically, and cysto-peritoneal shunt. One of the rare complications after rapid decompression of the arachnoid cysts is haemorrhage in the surrounding brain as well as in remote areas. We describe a case of multiple remote-site intra-parenchymal haemorrhage as a rare complication after surgical decompression of a sylvian fissure arachnoid cyst.

Intracranial tuberculoma is an uncommon presentation of tuberculosis, and its occurrence in an intraventricular location is very rare. It is usually confused with glioma, parasitic cyst, and craniopharyngioma. Few case reports exist in the literature on this entity. We report a case of tuberculoma at the foramen of Monro in a 7-year-old child and review the literature in terms of diagnostic dilemma.
