Pancoast tumour - a primary lung cancer that arises in the lung apex and invades soft tissues such as the brachial plexus. Although classically these tumours present with Pancoast syndrome (shoulder pain, C8 to T1 radiculopathy, Horner’s syndrome) this only occurs in approximately 25% of cases. The lung apex is an important check area on chest radiographs. Any density difference between the left and right is suspicious. CT in this case confirms a lung mass invading adjacent soft tissues and destroying the second rib.
A friend of ours sent a recent X-ray of his cervical ribs. He is also a medical student and decided to share his experience.
He wrote:”you can see them as bone structures above clavicles. They are not symmetrical (in most of cases they arenot). In the middle of right rib and in the distal part of left rib you can see additional joints. Both ribs start at C7 (i think so) and end with joints at 1st thoracic rib. It is quite rare condition (0,2 % of population) and may lead to thoracic outlet syndrome. Cervical rib may be resected if thoracic outlet syndrome occurs. Also you can see crooked 8th tooth and a earring :).”
We are so grateful for having someone willing to share his experience so we can all learn together!! THANK YOU! :)
Transpyloric Plane (L1)
This is such a significant CT plane as it contains the following important structures:
- Fundus of gall bladder
- Superior mesenteric artery origin
- End of the spinal cord
- Pylorus of stomach
- Neck of pancreas
- Origin of portal vein
- 2nd part of the duodenum / sphincter of Oddi
- Hilum of kidneys
- Duodenal-jejunal flexure
- Hepatic / splenic flexure of large bowel
Adenosine deaminase deficiency, in three words:
- Second most common for of SCID
- Ribonucleotide reductase Inhibited by excess dATP, which prevents DNA synthesis and thus decreases lymphocyte count (lymphocytes are some of the more mitotically active cells in the body)
- Very early infections. Candidiasis, diarrhea, respiratory. Distinguish from Wiskott-Aldrich’s in that the platelet count is normal.
