1/121. Thoracolithiasis.Thoracolithiasis without any history of chest traumas or interventions is pathologically rare, with only 9 cases including our 2, reported thus far in the literature. Case 1: A 76-year-old man admitted to our hospital had an abnormal shadow in chest radiography that gradually enlarged. serum carcinoembrionic antigen was slightly elevated during follow-up. A milky white tumor 1.5 cm in diameter with many projections was found in the thoracic cavity and removed by thoracoscopy. Histopathological examination showed the tumor to consist of fibrous tissue with fatty necrosis at the core. Case 2: A 54-year-old woman admitted to our hospital had an abnormal shadow in chest screening radiography in 1998. Transbronchial biopsy showed this shadow to be lung adenocarcinoma. A small trigonal pyramid-shaped milky white nodule 5 mm in diameter was found in the thorax during lobectomy for lung cancer. Histopathological examination showed this nodule also to consist of fibrous tissue with fatty necrosis.- - - - - - - - - - ranking = 1keywords = lithiasis (Clic here for more details about this article) |
2/121. Urethral diverticulum with lithiasis.Urethral diverticulum, either congenital or acquired, is very rare and becomes symptomatic when complicated by infection and lithiasis. This paper reports on such a case that was cured by radical excision of the lesion.- - - - - - - - - - ranking = 1keywords = lithiasis (Clic here for more details about this article) |
3/121. Testicular seminoma in a man with bilateral microlithiasis and a history of cryptorchidism.A case is presented of a young man with a history of bilateral cryptorchidism who presented with infertility. On investigation he was noted to have bilateral microlithiasis and left testicular seminoma. The possible association between microlithiasis and seminoma in patients with a history of cryptorchidism is discussed.- - - - - - - - - - ranking = 1.2keywords = lithiasis (Clic here for more details about this article) |
4/121. portal vein phlebolithiasis found post-liver transplantation in the native liver of a child with biliary atresia.biliary atresia is defined as partial or total obliteration of the extra-hepatic bile ducts. In advanced cases, liver transplantation (LTx) is considered the most appropriate treatment. This report describes a female patient whose biliary atresia and subsequent cirrhosis required LTx at 1 yr of age. Macroscopic inspection of the hilar region of the native liver post-Tx revealed the formation of a pouch in the hepatic duct and a stone in the lumen of the portal vein. x-ray diffraction analysis showed that the stone was composed of cholesteryl cinnamate, gluconic acid phenylhydrazide, Na beta broma-allyl mercaptomethyl penicillinate, and Al2O3 crystals. While the cholesterol component is a known element of gallstones, we attributed the Na beta broma-allyl mercaptomethyl penicillinate to the patient's drug therapy. Our literature search revealed no previous record or crystallographic analysis of portal vein phlebolithiasis. In this report we describe this rare finding.- - - - - - - - - - ranking = 1keywords = lithiasis (Clic here for more details about this article) |

6/121. Localizing signs in positional vertigo due to lateral canal cupulolithiasis.BACKGROUND: Different types of benign positional vertigo (BPV) have been recognized. The variant with permanent apogeotropic direction-changing lateral nystagmus in the supine position is particularly difficult to distinguish from central etiologies. OBJECTIVE: To identify clinical features of this variant of BPV, helping to establish its peripheral etiology. methods: In five patients without any evidence of neurologic disease and with this variant of positional vertigo, the behavior of nystagmus as a function of head position in space was studied. RESULTS: In the supine position, a null point for lateral nystagmus was identified, beyond which the nystagmus changed direction. This null point was evident when the head was turned 10 to 20 degrees to the side. In this position, the ipsilateral cupula of the lateral semicircular canal is aligned with the gravity vector. In two of the five patients, a null point was identified in pitch, beyond which the nystagmus reversed direction. This null point corresponds to the head position where the lateral canals are in an earth horizontal plane. CONCLUSION: From the behavior of lateral nystagmus in different head positions, the lateral canal system of the inner ear is shown to be gravity-sensitive and the side on which the cupula is affected can be determined.- - - - - - - - - - ranking = 0.8keywords = lithiasis (Clic here for more details about this article) |
7/121. Mediastinal abscess due to passage of a broncholith.We report a case of a 32-year-old woman who, after passage of broncholiths, developed a mediastinal abscess that required surgical drainage for treatment. Previously reported infectious complications resulting from broncholiths include obstructive pneumonitis and recurrent aspiration pneumonitis secondary to bronchoesophageal fistulas. Because radiographic evidence of abnormal calcification in the chest is common, but rarely is associated with broncholithiasis, the patient's history of lithoptysis was crucial to determining the underlying etiology of her abscess.- - - - - - - - - - ranking = 0.2keywords = lithiasis (Clic here for more details about this article) |
8/121. Positional down beating nystagmus in 50 patients: cerebellar disorders and possible anterior semicircular canalithiasis.OBJECTIVES: To clarify the clinical significance of positional down beat nystagmus (pDBN). methods: A discussion of the neuro-otological findings in 50 consecutive patients with pDBN. RESULTS: In 38 patients there was evidence of CNS disease (central group) but in 12 there was not (idiopathic group). In the CNS group, presenting symptoms were gait, speech, and autonomic dysfunction whereas in the idiopathic group patients mostly reported positional vertigo. The main neurological and oculomotor signs in the CNS group were explained by cerebellar dysfunction, including 13 patients with multiple system atrophy. In patients with multiple system atrophy with a prominent extrapyramidal component, the presence of pDBN was helpful in the differential diagnosis of atypical parkinsonism. No patient with pDBN had the arnold-chiari malformation, a common cause of constant down beat nystagmus (DBN). In the idiopathic group, the pDBN had characteristics which suggested a peripheral labyrinthine disorder: vertigo, adaptation, and habituation. In six patients an additional torsional component was found (concurrently with the pDBN in three). Features unusual for peripheral disorder were: bilateral positive Dix-Hallpike manoeuvre in nine of 12 patients and selective provocation by the straight head-hanging manoeuvre in two. CONCLUSION: It is argued that some patients with idiopathic pDBN have benign paroxysmal positional vertigo (BPPV) with lithiasis of the anterior canal. The torsional component may be weak, because of the predominantly sagittal orientation of the anterior canal, and may not be readily seen clinically. Nystagmus provocation by bilateral Dix-Hallpike and straight head-hanging may be explained by the vertical upwards orientation of the ampullary segment of the anterior canal in the normal upright head position. Such orientation makes right-left specificity with the Dix-Hallpike manoeuvre less important than for posterior canal BPPV. This orientation requires a further downwards movement of the head, often achieved with the straight head-hanging position, to provoke migration of the canaliths. The straight head-hanging manoeuvre should be carried out in all patients with a history of positional vertigo and a negative Dix-Hallpike manoeuvre.- - - - - - - - - - ranking = 1keywords = lithiasis (Clic here for more details about this article) |
9/121. Calcified intraluminal meconium in newborn males with imperforate anus. Enterolithiasis in the newborn.Five cases are reported and reference is made to 3 previous similar cases of calcified intraluminal meconium in newborn males with "imperforate anus." A rectourinary fistula was found in most of the patients; none of the cases had meconium peritonitis. The calcifications may develop in areas of prolonged stasis; the possible added role of the mixture of urine and meconium in utero is raised.- - - - - - - - - - ranking = 0.8keywords = lithiasis (Clic here for more details about this article) |
10/121. Case of mediastinal seminoma with testicular microlithiasis.Testicular microlithiasis is a rare condition in which calcified concretions fill the lumina of the seminiferous tubules. We report the case of a 19-year-old Japanese man with mediastinal seminoma, normal testicular physical findings and bilateral testicular microlithiasis seen on ultrasonography. Testicular needle biopsy demonstrated multiple laminated calcifications within the seminiferous tubules without any signals of a viable germ cell tumor. To our knowledge, this is only the sixth reported case of extragonadal germ cell tumor with testicular microlithiasis.- - - - - - - - - - ranking = 1.4keywords = lithiasis (Clic here for more details about this article) |
