Neurenteric cyst Neurenteric cyst. Dr Henry Knipe ◉ and Dr Maxime St-Amant et al. Neurenteric cysts are a rare type of foregut duplication cyst, accounting for ~1% of all spinal cord tumours. They are usually classified as spinal or intracranial, and are associated with vertebral or CNS abnormalities respectively.

- Neurenteric cysts are rare, benign, congenital, endodermal lesions, more commonly located in the spine than in the brain. The posterior fossa is the usual brain location, typically in the midline, anterior to the brainstem, in the cerebellopontine angle. Supratentorial localizations are very rare [32, 33].

hydronephrosis Hydronephrosis is the swelling of the kidneys when urine flow is obstructed in any of part of the urinary tract. Swelling of the ureter, which always accompanies hydronephrosis, is called hydroureter.Hydronephrosis implies that a ureter and the renal pelvis (the connection of the ureter to the kidney) are overfilled with urine.ydronephrosis is the distention of the pelvis and calyces of one or both kidneys, resulting in thinning of the renal tubules because of obstructed urinary flow. When the obstruction is a stone or kink in one of the ureters, only one kidney is damaged.

Sycosis Materia Medica Medical dictionary defines sycosis as Hahnemann’s term for the constitutional effects of the gonorrhoeal virus. To Hahnemann sycosis was essentially a diathesis producing warts or wart like growth. He, therefore called sycosis the fig wart disease (Y.R.A.) Gonorrhoea is caused by the kidney shaped microbe, Neisseria gonococcus. According to Dr. Younan by sycosis we understand that morbid constitution induced by the gonorrhoea poison, especially when inappropriately treated.

sebaceous cyst A harmless soft swelling within the skin, consisting of an accumulation of fatty sebaceous material (SEBUM), the normal secretion of the sebaceous glands of the skin. Cysts develop when a gland opening becomes blocked. Sebaceous cysts, however large, are easily treated by a simple surgical operation.

Prostatic utricle cyst â a case report and review of current literature The complications arising from these cysts can be pain, hematuria, ejaculatory duct obstruction, epididymitis, and calculi formation [2] and in rare cases malignant transformation [4]. Gupta et al had reported a case of mullerian duct cysts presenting as a recurrent intra-abdominal mass [5].

- A cyst is an abnormal growth that develops as a closed sac somewhere in the body. A dermoid cyst is a specialized type of cyst that contains skin and skin appendages, which include hair follicles and sweat glands. Dermoid cysts have different names depending on where in the body they form and what types of structures are inside them. It can be a bit confusing. For example, a dermoid cyst that contains many types of cells, such as skin, hair, teeth, fat, bone and nerve cells, is called a teratoma.

Perineural Cysts Perineural cysts, which are also known as Tarlov cysts, are fluid-filled sacs that form on nerves at the base of the spine. A person with such cysts would likely never know it.

Arachnoid Cysts Arachnoid cysts are fluid-filled sacs that occur on the arachnoid membrane that covers the brain (intracranial) and the spinal cord (spinal). There are three membranes covering these parts of the central nervous system: the dura mater, arachnoid, and pia mater. Arachnoid cysts appear on the arachnoid membrane, and they may also expand into the space between the pia mater and arachnoid membranes (subarachnoid space).

- Overview. Arachnoid cysts are benign cysts that occur in the cerebrospinal axis in relation to the arachnoid membrane and that do not communicate with the ventricular system. They usually contain clear, colorless fluid that is most likely normal cerebrospinal fluid; rarely, they contain xanthochromic fluid.rachnoid cysts are benign cysts that occur in the cerebrospinal axis in relation to the arachnoid membrane and that do not communicate with the ventricular system.

Cystathioninuria Cystathioninuria, also called cystathionase deficiency, is an autosomal recessive metabolic disorder that results in an excess of cystathionine in the urine. It is associated with a congenital dysfunction of the enzyme cystathionase, or acquired deficiency of vitamin B6 which is essential for the function of this enzyme. The latter is usually related to an overall deficiency of all the B-complex vitamins.

Overview A kidney cyst is a fluid-filled sac that grows in your kidneys, which are the bean-shaped organs that filter wastes out of your bloodstream to produce urine. You might have a single cyst on one kidney or many cysts on both kidneys. There are two types of cysts: simple cysts and polycystic kidney disease. Simple cysts are individual cysts that form on the kidneys. They have thin walls and contain a water-like fluid. Simple cysts don’t damage the kidneys or affect their function.

Renal Cysts Renal cysts are sacs of fluid that form in the kidneys. Most of the time, they are simple kidney cysts, meaning they have a thin wall and only water-like fluid inside. They are fairly common in older people and typically do not cause any symptoms or harm.enal Cysts. Renal cysts are sacs of fluid that form in the kidneys. They are usually characterized as “simple” cysts, meaning they have a thin wall and contain water-like fluid. Renal cysts are fairly common in older people and usually do not cause symptoms or harm.

Tapeworms Cysticercosis is an infection caused by the larval stages of the parasite Taenia solium, after a person ingests tapeworm eggs. The larvae embed in tissues such as muscle and brain, forming cysticerci (cysts). When cysticerci are found in the brain, the condition is called neurocysticercosis. (Common cause of seizures of the developing world).

Renal cyst A renal cyst is a fluid collection in the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon.

A kidney cyst or renal cyst, is a fluid collection within the kidney. They are quite common, and the incidence increases with advancing age. Kidney cysts may be part of a genetic disease that results in a slow, progressive decrease in kidney function. In this scenario, there is usually a family history of kidney disease.

- Perineural cysts, which are also known as Tarlov cysts, are fluid-filled sacs that form on nerves at the base of the spine. A person with such cysts would likely never know it. They almost never cause symptoms. When they do cause symptoms, however, the most common is pain in the lower back, buttocks, and legs.

Hydronephrosis of the Kidney - definition, symptoms and treatment What is Hydronephrosis of the Kidney and Definition. A circumstance in which the renal pelvis, the portion of the kidney that collects URINE for passage from the kidney via the URETER, dilates and enlarges. Hydronephrosis results from conditions of the kidney that slow or block the flow of urine, causing urine to back up into or pool in the renal pelvis.

Definition and Description Tarlov cysts (hereafter referred to as TCs) are also known as perineural/perineurial, or sacral nerve root cysts. They are dilations of the nerve root sheaths and are abnormal sacs filled with cerebrospinal fluid (hereafter referred to as CSF) that can cause a progressively painful radiculopathy (nerve pain).erineural cysts can form in any section of the spine; a significant percentage (11%) of patients have cysts at more than one location of the spine.. Some patients have cysts at all sections of the spine, including cervical, thoracic, lumbar, and sacral.
