Fabella is a sesamoid bone, located within the tendon of the lateral head of the gastrocnemius muscle. It may be associated with posterolateral knee pain because of repetitive friction over the posterolateral femoral condyle. We report a case of a 64-year-old woman presenting with right posterolateral knee pain. F-NaF PET-CT demonstrated increased uptake posterior to the right knee joint localizing to a fabella. Standard examination and radiographic imaging excluded other causes for posterolateral knee pain, and the increased activity was considered to be secondary to fabella syndrome...

Delayed presentations have been reported following gunshot wounds (GSW) with retained intraspinal bullets due to migration of projectile or lead intoxication. We report on the rare occurrence of delayed pyogenic spondylodiscitis and neurological dysfunction following injury from low velocity GSW to the spine with a retained projectile. A 55-year-old male presented 4 months following GSW to the abdomen which resulted in colonic injury and L5 fracture. The patient was treated initially with ileo-transverse anastomosis, antibiotics, without retrieval of the bullet...

The interposition of a portion of the colon between the liver and the diaphragm is called Chilaiditi sign and discovered incidentally during radiological study for other reasons and usually asymptomatic presentation. When the discovery is accompanied by clinical symptoms such as abdominal pain, nausea, vomiting, bloating, constipation called Chilaiditi Syndrome. The Chilaiditi sign is a very rare condition, and the Chilaiditi syndrome is even more, especially if associated with other acute diseases. We report the case of a man of 41 years was admitted with right upper quadrant abdominal pain, nausea, vomiting, difficulty was diagnosed with radiographic and tomographic images making the differential diagnosis with lung abscess and diaphragmatic hernia...

Adrenal teratomas are rare neoplasms and there is limited data on their surgical outcomes and long-term prognosis. We aimed to review our institutional experience and compare this to the existing literature on adrenal teratomas in adults and children. An institutional pathology database was searched for cases of adrenal teratoma (June 1956-July 2016). Clinical and imaging data were abstracted from the medical records and pathology slides were obtained for review. In addition, a PubMed search for "adrenal teratoma" from June 1952 to July 2016 was performed to identify reports of primary adrenal teratoma in patients of all ages...

The sigmoid sinus is routinely exposed and manipulated during pre-sigmoid, transpetrosal approaches to the skull base, but there is scant data available on the incidence of venous sinus compromise after surgery. We encountered a dural arteriovenous fistula as a result of sigmoid sinus occlusion and examined the incidence of venous sinus thrombosis or narrowing after transpetrosal surgeries. We performed a retrospective analysis of a series of patients treated by the senior surgeons (WCJ, MH, HJK), who underwent either a posterior petrosectomy or translabyrinthine approach for various skull base tumors...

BACKGROUND: Persistent elbow instability associated with coronoid deficiency is a difficult condition to treat. Several surgical techniques have been described for coronoid reconstruction, but the resulting outcomes have been unpredictable. We hypothesized that a coronoid prosthesis could restore elbow stability. METHODS: A nonanatomically shaped metallic coronoid prosthesis was custom designed for each of 3 patients. Each had a chronic fracture-subluxation with persistent instability, deficiencies of the coronoid, and compromise of the radial head...
