Atypical multifocal hydatid disease of cranial vault: simultaneous orbital and extradural meningeal involvement.

Hydatid disease is endemic in regions where livestock is raised. Liver and lungs are the most commonly affected organs by the disease. Cranial vault and orbital hydatid disease is extremely rare. Signs and symptoms along with serological investigation are often inconclusive in cranial hydatid, making radiological diagnosis extremely important. Surgical removal of the cyst is the mainstay of treatment. Postoperative medical therapy, along with regular follow-up, is the key to detect any recurrence. We report an unusual case of cranial hydatid which showed diffuse scalp infiltration along with oribital and extradural extension.

Persistent port-site sinus in a patient after laparoscopic cholecystectomy: watch out for gallbladder tuberculosis.

BACKGROUND The gallbladder is rarely affected by mycobacterium tuberculosis. The diagnosis of gallbladder tuberculosis is often not suspected prior to surgery or biopsy. METHOD A young female patient underwent laparoscopic cholecystectomy but presented with a persistently discharging sinus from the port site. RESULTS The gallbladder biopsy revealed granulomas typical of chronic granulomatous tuberculosis. The condition of the patient was improved by antitubercular treatment. CONCLUSIONS Presentation of gallbladder tuberculosis as a persistent discharging sinus at the port site in a patient who has undergone a laparoscopic cholecystectomy is extremely rare. The diagnosis was reached by histopathology only. The rarity of the presentation prompted us to report the case.

Isolated tubercular scaphoid osteomyelitis: a case report

Bone is the third most frequent site of tuberculosis after lung and lymph node, accounting for 10%–20% of all cases of extrapulmonary disease. The spine and hip are the most commonly involved sites. Involvement of the small bones of the hand has been described exceedingly rarely, and is usually secondary to pulmonary disease. Because a primary focus is not always found, it can be difficult to make a diagnosis of skeletal tuberculosis. Moreover, because clinical and radiographic features are nonspecific, an early diagnosis will only be made where there is a high degree of suspicion. Isolated osteomyelitis of the scaphoid is uncommon, having previously been reported in association with animal bites and interventions such as radial artery cannulation. We describe here the unusual occurrence of tubercular osteomyelitis of the scaphoid, a condition which has rarely been reported.

The bull's eye sign and other suprainguinal venographic findings to limit the use of intravascular ultrasound in patients with severe venous stasis

OBJECTIVE When assessing the common femoral and suprainguinal veins in patients with venous stasis, it is generally agreed that use of intravascular ultrasound (IVUS) is mandatory. This widely held dogma is reinforced by the fact that extrinsic compression of the iliac veins does not reproduce images consistent with eccentric stenosis as one sees in the arterial system. In an attempt to identify a subgroup of patients where the use of IVUS could be averted, we analyzed and carefully evaluated the images of patients who had both standard contrast venograms and IVUS examinations. METHODS Ninety-two common femoral and suprainguinal venograms performed during a recent 6-month period were randomly selected for analysis. Good quality venographic images were found in 88 of these limbs (78 patients) that also had IVUS data formed the basis of this analysis. All venograms included visualization of the common femoral, external and common iliac veins, and inferior vena cava. These veins were classified as (1) normal to mild (type I) vein narrowing or dilatation of ≤20% compared with the adjacent segment, (2) moderate (type II) ≥21%-40%, (3) severe (type III) ≥41%, and (4) bulls eye sign (type IV). The latter was defined as a central circle with minimal or no dye within a dilated vein and forking of the dye around the circle. RESULTS In the present series, no 1-month mortality or 1-month morbidity was observed in these patients. The Clinical, Etiologic, Anatomic, and Pathologic (CEAP) classification score was class II in 24 cases (26%), class III in 36 cases (39%), class IV in 17 cases (18%), class V in nine cases (10%), and class VI in six cases (7%). There was no venographic or IVUS evidence of inferior vena cava stenosis or dilatation in this series. Of the venograms studied, 88 had positive intravascular ultrasound (PIVUS) or positive predictive value findings. The correlation of venographic findings and PIVUS was as follows: type I cases (26) had 85% PIVUS; type II (22) had 100% PIVUS; type III (25) had 100% PIVUS, and type IV (19) had 100% PIVUS. CONCLUSIONS The new proposed classification of venographic findings can be used to treat more than two-thirds of the patients without resorting to the use of IVUS.

Clinico-radiological and pathological evaluation of extra testicular scrotal lesions.

Background: Scrotal ultrasound, though reliable in distinguishing between intratesticular and extratesticular lesions and characterizing them as cystic and solid, cannot distinguish benign from malignant pathology. Although fine needle aspiration cytology (FNAC) has proved to be of great diagnostic importance in testicular lesions, its scope in extratesticular lesions is largely unexplored. Aim: To evaluate extratesticular scrotal lesions cytologically and compare it with their clinical, radiological, and histological findings. Materials and Methods: Sixty five patients with extratesticular scrotal lesions were assessed clinically, radiologically, and cytologically. Histopathology was done in 45 cases where surgical exploration was undertaken. All the data were then analyzed and correlated. Results: Extratesticular lesions accounted for 72.2% of the scrotal swellings. Of these, the epididymis is most commonly involved (61.5% cases) with the commonest type of lesion being cystic (49.3% cases). Ultrasonography preferably with color doppler is highly useful for the evaluation of the scrotum. Apart from distinguishing extratesticular from testicular and cystic from solid lesions, it has an important role in identifying individual lesions, thus reducing the list of differential diagnosis. Fine needle aspiration cytology contributed to a definitive diagnosis in 47.7% cases. It helps classify cystic masses on the basis of their contents and defines the etiology of chronic inflammatory lesions, apart from corroborating with the clinico-radiological diagnosis. Histological evaluation was possible only in cases where surgery was performed and helps further define the diagnosis. Conclusion: Fine needle aspiration cytology is essentially non-traumatic and easy to carry out and should be a technique of choice for the study of scrotal pathology, main advantage being avoidance of delays in diagnosis.

Safety and efficacy of stenting nonthrombotic iliac vein lesions in octogenarians and nonagenarians in an office setting

Objectives Treatment options for venous insufficiency are rapidly evolving in the office setting and include venography, intravascular ultrasound, and venous stenting. Non-thrombotic iliac vein lesions assessment and treatment in an office setting is currently an area of interest. The purpose of this study is to demonstrate the safety and efficacy of evaluating non-thrombotic iliac vein lesion with this office-based procedure in octogenarians and nonagenarians. Methods From January 2012 through December 2013, 300 non-thrombotic iliac vein lesion limbs in 192 patients with venous insufficiency ≥80 years old were evaluated for non-thrombotic iliac vein lesion. Patients were evaluated and treated with venography, intravascular ultrasound, and stent placement for significant lesions demonstrated by greater than 50% diameter or cross-sectional area reduction. Group 1: 168 of these patients were octogenarians; female/male ratio was 1.75:1, bilateral in 89/168 patients (53%), left sided in 131/259 limbs (51%), right sided in 128 limbs (49%), average age 83.5 ± 2.6 years (range 80–89) compared to Group 2: 24 nonagenarians; female/male was 3:1, bilateral in 17/24 patients (70%), left sided in 20/41 limbs (49%), right sided in 21/41 limbs (51%), average age 92.9 ± 2.2 years (range 90–99). Stent related outcomes were evaluated with communication to the patient within 24 h to assess post-procedure pain followed by serial iliocaval ultrasonography. Results Out of the 300 limbs evaluated, in Group 1, 86% of limbs had stents placed compared to 90% in Group 2 and 11% of both groups had two stents placed. Overall improvement in pain, edema, and ulcers was reported in 147 (59%) of octogenarians and 24 (65%) of nonagenarians. There were no surgical site infections, pseudo-aneurysms, arteriovenous fistulas, or femoral artery injuries. No patients required transfusion within three days post-operatively and there were no 30-day mortalities in both sets of patients. Conclusions Our results demonstrate that there is no statistical difference in the outcome of performing venography, intravascular ultrasound, and stent placement in an office-based setting in octogenarians and nonagenarians. Both groups maintained a similar safety profile with low morbidity and mortality. In conclusion, we believe that the treatment of non-thrombotic iliac vein lesion in an office-based setting is safe and efficacious in both groups.

Ruptured abdominal aortic aneurysm after endovascular aortic aneurysm repair thrombosis

Background Complete thrombosis of an aortic endograft after an endovascular aortic aneurysm repair is a rare complication. The majority of thrombotic events occur in the iliac limbs. Case presentation We present the case of a patient who presented with acute limb ischemia as the result of a thrombosed infra-renal aortic endograft. After restoration of blood flow to the lower extremities with an axillary to bi-femoral artery bypass, the patient was lost to follow-up. The patient returned two years later with a ruptured abdominal aortic aneurysm due to a type 1A endoleak. Discussion We propose that all patients after endovascular aortic aneurysm repair, including those with a thrombosed aortic endograft, continue to undergo regular graft surveillance. This case report highlights the importance of continued surveillance of the aortic sac, even after total thrombosis of the endovascular aortic aneurysm repair.

A Standardized Ultrasound Scoring System for Preoperative Prediction of Difficult Laparoscopic Cholecystectomy

Purpose Laparoscopic cholecystectomy (LC) has become the treatment of choice for cholelithiasis. Still some patients required conversion to open cholecystectomy (OC). Our aim was to develop a standardized Ultrasound based scoring system for preoperative prediction of difficult LC. Methods and materials Ultrasound findings of 300 patients who underwent LC were reviewed retrospectively. Four parameters (time taken, biliary leakage, duct or arterial injury, and conversion) were analyzed to classify LC as easy or difficult. The following ultrasound findings were analyzed: GB wall thickness, pericholecystic collection, distended GB, impacted stones, multiple stones, CBD diameter and liver size. Out of seven parameters, four were statistically significant in our study. A score of 2 was assigned for the presence of each significant finding and a score of 1 was assigned for the remaining parameters to a total score of 11. A cut-off value of 5 was taken to predict easy and difficult LC. Results 66 out of 83 cases of difficult LC and 199 out of 217 cases of easy LC were correctly predicted on the basis of scoring system. A score of >5 had sensitivity 80.7% and specificity 91.7% for correctly identifying difficult LC. Prediction came true in 78.8% difficult and 92.6% easy cases. US findings of GB wall thickness, distended GB, impacted stones and dilated CBD were found statistically significant. Conclusion This indigenous scoring system is effective in predicting conversion risk of LC to OC. Patients having high risk may be informed and scheduled appropriately and decision to convert to OC in case of anticipated difficulty may be taken earlier.
