It refers to the position of a penis as it relates to pathology on an X-ray of a pelvis. When the penis (visible on the X-ray as a shadow) points towards the same side as a unilateral medical condition such as a broken bone, this is considered a "positive John Thomas sign," and if the shadow points to the other side, it is a "negative John ...
These lymph nodes are also known as glands or lymphoid tissue. If they detect something foreign passing through them, they enlarge. This is called lymphadenopathy or swollen glands. Usually this is localized (for example, an infected spot on the scalp will cause lymph nodes in the neck on
Swollen lymph node in the neck due to tick attached behind ear. Cervical lymphadenopathy refers to lymphadenopathy of the cervical lymph nodes (the glands in the neck). The term lymphadenopathy strictly speaking refers to disease of the lymph nodes, [1] though it is often used to describe the enlargement of the lymph nodes.
The corona and the neck are highly vascularized areas of the penis. The axial and dorsal penile arteries merge together at the neck before entering the glans. [8] Branches of the dorsal artery of the penis curve around the distal shaft to enter the frenulum and the glans from its ventral surface. [9]
Virchow's nodes are named after Rudolf Virchow (1821–1902), the German pathologist who first described the nodes and their association with gastric cancer in 1848. [4] The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the nodes.
The x-ray film or image of the lymphatic vessels and lymph nodes is called a lymphogram or a lymphangiogram. Radiographs can be taken after injection of a radiopaque contrast medium into small lymphatic vessels (these are made visible by prior subcutaneous injection of patent blue dye). The resulting lymphogram is used to find the locations of ...

Caldwell's view (or Occipitofrontal view) is a radiographic view of the skull where the X-ray plate is perpendicular to the orbitomeatal line. The rays pass from behind the head and are angled at 15-20° to the radiographic plate. It is commonly used to get better view of the ethmoid and frontal sinuses. [1]
