A 40-year-old man presented with left-side nasal obstruction for the past nine months. He had been treated for allergic rhinitis with nasal steroids for a long time. An anterior rhinoscopic examination was normal. Endoscopic examination revealed a nodulary mass in the nasopharynx, partially obstructing the left choana (Figure 1A). An endoscopic examination of the right nasopharynx revealed regu...

OBJECTIVE To determine the association of high occlusal force (HOF) with the signs of occlusal trauma and periodontal conditions in periodontitis patients, and elaborate the relevant clinical implications. METHODS Periodontal parameters and signs of occlusal trauma were recorded for 807 teeth in 30 subjects with untreated chronic periodontitis. The T-scan II occlusal analysis system determine...

A 50-year-old woman presented with a 5-year history of mild pain in her right knee, which had increased over the last 2 years. A palpable mass over the anterolateral aspect of the knee was obvious and the last 3 months she was experiencing locking episodes with consequent knee effusion. The differential diagnosis was driven between meniscal cyst, pigmented villonodular synovitis, synovial sarco...

The inflammatory paradental cyst (IPC) is a relatively rarely reported lesion arising from the lateral periodontium of vital teeth. However, IPC appear to be under-represented in registers of odontogenic cysts due to the misinterpretation of IPC as infected dentigerous cysts, in particular IPC originating from third molars. IPCs exhibit some temporospatial associations with tooth eruptions and ...

Epidermal cysts are intradermal or subcutaneous cystic tumors that frequently occur in the face, scalp, neck, and body trunk. Acquired cases of epidermal cyst commonly occur as a result of various surgical operations, chronic irritation, or trauma, all of which may trigger the occurrence of the invagination of squamous epithelium. A 57-year-old man presented with a palpable mass 7 cm×2 cm in si...

A 59-year-old woman was seen 3 months after laminectomy at L3-L5 and diskectomy at L3-L4 for central herniated disk. She had occipital headaches exacerbated by coughing and low back pain radiating to the right leg. On examination a small , nontender, fluctuant mass was noted lateral to the laminectomy incision. Sonography showed a multilocular cyst at the L3 level with a large, deeper component...

Dear Editor, Two cases with epiphora and medial canthal mass showed a cyst within the lacrimal sac that compressed the lacrimal drainage system. We describe a new lacrimal sac anomaly of lacrimal intrasaccal cyst, which has not yet been reported. A 31-year-old woman was referred for epiphora in her left eye for 17 years. She also presented with a 10-year history of a palpable mass below the med...

BACKGROUND Echinococcosis in humans occurs as a result of infection by the larval stages of taeniid cestodes of the genus echinococcus. Intracranial hydatid cysts usually develop at an intraparenchymal site. Hydatid cyst within the cerebral ventricle is quite unusual. METHODS We reviewed the literature on adult intraventricular hydatid cyst and found case reports mainly in children with an on...

The patient was a 45-year-old man with a progressive headache. Evaluation in detail revealed it as a case of left lateral ventricular space occupying lesion (SOL) resembling choroid plexus papilloma. A left parietal craniotomy was done and the lesion was removed completely through intraparietal approach. Surgical removal resulted in complete symptomatic relief. Histopathology revealed that it w...

UNLABELLED The complications of the hydatid cyst of the liver are dominated by infection and rupture. The compression of adjacent organs (mainly the inferior vena cava, the portal vein and the bile ducts) can be seen, when the cyst is located in the dome, in the hilum or within the hepatic parenchyma. Upper digestive stenosis by compression of the duodenum by the hydatid cyst is an exceptional ...
