Pathak N et al: Should gut malrotation be suspected in adolescents and young adults presenting with failure to thrive? Most duplication cysts have a similar spherical or tubular morphology with near water density antibiotic xi cheap 1000mg tinidazole amex, nonenhancing contents antimicrobial floor mats tinidazole 1000mg cheap. The mass results in partial small bowel obstruction antibiotic resistance of staphylococcus aureus buy tinidazole 500mg overnight delivery, accounting for the small bowel feces sign and dilation of upstream loops antibiotic used for pneumonia order tinidazole 1000mg fast delivery. One of the duodenal diverticula is fluid-filled and might be mistaken for a cystic lesion in the head of the pancreas. An adjacent blindending sac represents the Meckel diverticulum and it contains calcified enteroliths in its dependent portion. Barium mixes with enteric debris within the diverticulum, which shows no evidence of obstruction or perforation. Like most Meckel diverticula, especially in adults, this one was probably an asymptomatic incidental finding.

In spite of prompt diagnosis and treatment, the colitis progressed to perforation and emergency colectomy. The fold pattern of the ileum is more prominent than that of the jejunum, a reversal of the normal situation. Biopsy & response to a gluten-free diet confirmed the diagnosis of celiac disease. One segment of jejunum has focal thickening of the wall, which was found to be due to lymphoma. Patients with refractory sprue are at increased risk for both lymphoma and carcinoma of the bowel. Endoscopic biopsy of the jejunal mucosa revealed villi distended with macrophages full of periodic acid-Schiffpositive bacilli, diagnostic of Whipple disease. Note the irregular, moderate dilation of the intrahepatic bile ducts and splenomegaly. This patient had biopsy-proven bile duct wall infiltration and bowel with excessive mast cells, essentially diagnostic of systemic mastocytosis. Traditional barium studies remain valuable for evaluation of strictures, fistulas, and sinus tracts. The diagnosis of Crohn disease was confirmed on colonoscopy with biopsy of the terminal ileum. Fistulas are a key feature of the transmural inflammation caused by Crohn disease. Also note the disproportionate dilation of the duodenum, another common feature of scleroderma.

Occasionally, the haemorrhagic-cystic changes involve almost the entire lesion so that the neoplasm may be mistaken for a pseudocyst. A few tumours have been found to be attached to the pancreas or even in extrapancreatic locations {812, 914, 945}. A Tumour spread Only few metastasizing solid-pseudopapillary neoplasms have been reported {359, 1358}. Common metastatic sites include regional lymph nodes, the liver, peritoneum, and greater omentum {300, 2209, 1358}. Histopathology In large neoplasms, extensive necrosis is typical and the preserved tissue is usually found in the tumour periphery under the fibrous capsule. More centrally there is a pseudopapillary pattern, and these components often gradually merge into each B. B the pseudocystic neoplasm is attached to the spleen, and shows haemorrhagic necrosis. In both patterns, the uniform polyhedral cells are arranged around delicate, often hyalinized fibrovascular stalks with small vessels . In the solid parts, disseminated aggregates of neoplastic cells with foamy cytoplasm or cholesterol crystals surrounded by foreign body cells may be found. The spaces between the pseudopapillary structures are filled with red blood cells. The hyalinized connective tissue strands may contain foci of calcification and even ossification . The round to oval nuclei have finely dispersed chromatin and are often grooved or indented. Mitoses are usually rare, but in a few instances prominent mitotic activity is observed . The neoplastic tissue is usually well demarcated from the normal pancreas, although a fibrous capsule may be absent and invasion of tumour cell nests into the surrounding pancreatic tissue may occur {1193, 1358}. Criteria of malignancy Although criteria of malignancy have not yet been clearly established, it appears that unequivocal perineural invasion, angioinvasion, or deep invasion into the surrounding tissue indicate malignant behaviour, and such lesions should be classified as solid-pseudopapillary carcinoma. However, neoplasms in which the above-mentioned histological criteria of malignancy are not detected may also give rise to metastases. Consequently, benign appearing solid-pseudopapillary neoplasms must be classified as lesions of uncertain malignant potential. In this solid area, the uniform tumour cells are separated by vascular hyalinized stroma. The cellular reaction for alpha-1-antitrypsin and alpha-1antichymotrypsin is always intense, but only involves small cell clusters or single cells, a finding that is characteristic of this neoplasm. Cytokeratin is detected in 30% to 70% {963, 2195}, depending on the method of antigen retrieval applied. Solid-pseudopapillary neoplasm 247 Usually, the staining for keratin is focal and faint. Positive immunoreactivity for trypsin, chymotrypsin, amylase and/or phospholipase A2 has been reported {166, 1072, 1192, 1226, 1844}, but has not been confirmed by most other authors {812, 945, 1282}. Similarly, focal positivity for glucagon, somatostatin and/or insulin has been described in some tumours {1226, 2021, 2147}, but was not detected in most other cases {1072, 1282, 1844}. Neurosecretory-like granules have been described in a few tumours {867, 880, 1684, 2119, 2147}. Intermediate cell junctions are rarely observed and microvilli are lacking, but small intercellular spaces are frequent. An unbalanced translocation between chromosomes 13 and 17 resulting in a loss of 13q14qter and 17p11pter has been described in one solid-pseudopapillary neoplasm . Local spread or dissemination to the peritoneal cavity has been reported in the context of abdomi- Ultrastructure the neoplastic cells have round or markedly indented nuclei containing a small single nucleolus and a narrow rim of marginated heterochromatin. Zymogen-like granules of variable sizes (500-3000 nm) are conspicuous, probably representing deposits of alpha-1-antitrypsin. The contents of these granules commonly dis- nal trauma and rupture of the tumour . Even in patients who had local spread, recurrences {359, 999}, or metastases {234, 1192, 1642}, long disease-free periods have been recorded after initial diagnosis and resection. Only a few patients have died of a metastasizing solid-pseudopapillary neoplasm {1192, 1395}.

For postthrombotic syndrome, duplex ultrasound can recognize specific anatomical abnormalities in the venous lumen, wall, and valves. Reflux can be easily diagnosed with duplex ultrasound, although some controversy is present concerning the extent of the reflux detected compared with descending venography. Venous obstruction is more challenging to quantify; nevertheless, simple indirect signs, such as phasic-flow disappearance and lowflow velocity in the common femoral vein, suggest suprainguinal obstruction. Before operative recanalization, duplex ultrasound can be used to determine the procedure, feasibility, expected permeability, and safest venous access site; evaluate suprainguinal venous segments and infrainguinal vessels to determine the landing zone; distinguish between postthrombotic syndrome, primary and congenital incompetence, or compression. Duplex ultrasound is currently used during postoperative follow-up after repermeation and stenting to determine the permeability of the stented veins and recognize complications, such as thrombosis, residual stenosis, and intrastent intimal hyperplasia. Currently, duplex ultrasound is the first-line examination for postthrombotic syndrome diagnosis, preoperative investigation, and postoperative follow-up because it provides relevant information for the operative management of obstruction and reflux, even if the preoperative assessment must be completed by venography and other instrumental investigations.

Once entry into the cavity is accomplished, the clinician need merely establish bleeding into the lesion before closure. A static bone cyst is an anatomic indentation of the posterior lingual mandible that appears to resemble a cyst on radiographic examination (Box 10-14; Figure 10-49). This depression of the mandible is believed to be developmental, although almost all cases appear in adults, particularly men. The cause is unknown, but some have suggested that the lesion is due to entrapment of the salivary gland or other soft tissue during Treatment and Prognosis development of the mandible. Others have suggested that the cause is lingual mandibular cortical erosion from hyperplastic salivary gland tissue. Both demographic and anatomic findings are more consistent with the latter hypothesis. These defects occasionally may be noted bilaterally and rarely, anterior to the first molar region of the mandible. This lesion is entirely asymptomatic and is often observed as an incidental finding on panoramic radiographic films. It appears as a sharply circumscribed oval radiolucency beneath the level of the inferior alveolar canal, with encroachment on the inferior border of the mandible. The presence of salivary tissue within the defect may be confirmed by sialography. The appearance of a static bone cyst is usually pathognomonic, and no treatment is required. Other depressions of the cortical surface of the mandible have been reported, albeit rarely, within the parotid gland along the lateral or facial aspect of the mandibular ramus. Focal Osteoporotic Bone Marrow Defect Focal osteoporotic bone marrow defects (hematopoietic bone marrow defects) are uncommon lesions that typically present as asymptomatic, focal radiolucencies in areas where hematopoiesis is normally seen (angle of the mandible and maxillary tuberosity). Approximately 70% of these lesions occur in the posterior mandible; 70% occur in females. The pathogenesis of the osteoporotic marrow defect is unknown, although three theories have been proposed. One theory states that abnormal healing following tooth extraction may be responsible (Figure 10-50). Another theory proposes that residual remnants of fetal marrow may persist into adulthood, thus presenting as a focal lucency. Finally, this tissue may merely represent a focus of extramedullary hematopoiesis that becomes hyperplastic in adult life. Microscopic findings show a predominance of hematopoietic cells with relatively fewer fat cells. Within the cellular marrow, small lymphoid aggregates may be found, as well as megakaryocytes (Figure 10-51). Because of nonspecific radiographic findings, diagnosis by an incisional biopsy is generally desirable. Subsequent to the establishment of this diagnosis, no further treatment is necessary. Soft Tissue Cysts of the Neck Branchial Cyst/Cervical Lymphoepithelial Cyst Branchial (cleft) cysts, or cervical lymphoepithelial cysts, are located in the lateral portion of the neck, usually anterior to the sternomastoid muscle (Figure 10-52). These lesions may also appear in the submandibular area, adjacent to the parotid gland, or around the sternomastoid muscle. The floor of the mouth is the most common site for these lesions, followed by the posterior lateral tongue. At one time, the branchial cyst was thought to occur because of incomplete obliteration of the branchial clefts, with epithelial remnants ultimately undergoing cystic change. The current theory of origin proposes that epithelium is entrapped in cervical lymph nodes during embryogenesis (Box 10-15).
