Adrenal morphology and cortical function in patients with extrapulmonary tuberculosis: response to antituberculosis treatment

ABSTRACT Objective: Enlargement of the adrenal glands and variable adrenocortical function have been reported in patients with pulmonary tuberculosis and, in a few studies, in patients with extrapulmonary tuberculosis (EPTB). However, none of the studies have evaluated the course of the adrenal morphology in these patients. Subjects and methods: Prospective study including 37 patients with EPTB and 37 healthy age- and sex-matched controls. The adrenal function was evaluated by measurement of cortisol levels at baseline and after stimulation with ACTH (Acton Prolongatum) before and 6 months after antituberculosis treatment. The size of both adrenal glands was evaluated using 64-slice computed tomography (CT) scanning before and 6 months after treatment. The findings were compared with those in a group of healthy matched controls. Results: Clinical and biochemical parameters were comparable between groups. The mean baseline serum cortisol level was significantly lower in the EPTB group (397.1 ± 184.9 nmol/L) compared with the control group (696.3 ± 101.8 nmol/L). Compared with controls, patients with EPTB had significantly lower mean cortisol levels at baseline and 1 hour after ACTH, both before (397 ± 184.9 nmol/L and 750.7 ± 176.8 nmol/L, respectively) and after (529.7 ± 100.4 nmol/L and 1017.2 ± 119.7 nmol/L, respectively) antituberculosis treatment. Both the length and thickness of the right and left adrenal glands were greater in patients with EPTB than in controls but became comparable to those in controls after treatment completion. Conclusions: Patients with EPTB have an enlarged adrenal size and low baseline and stimulated serum cortisol levels. After treatment completion, cortisol levels increased significantly, and the adrenal size normalized in these patients

Involvement of the cervical cord and medulla in posterior reversible encephalopathy syndrome

The posterior reversible encephalopathy syndrome (PRES) is characterized by patchy cortical and subcortical lesions in the distribution of the posterior circulation. The lesions are classically reversible. This syndrome has multiple etiologies, most of which cause acute hypertension. We present a case of PRES with involvement of the medulla and cervical cord (apart from the typical parieto-occipital lesions)-an extremely rare imaging manifestation of PRES. It is important to recognize the imaging findings of PRES in spinal cord, and avoid misdiagnosis as myelitis by proper clinical correlation. Typically patients with myelitis have a profound neurodeficit, while patients with spinal manifestations of PRES are asymptomatic. Involvement of the cord in PRES has probably been an underrecognized entity as spinal imaging is not routinely performed in posterior reversible encephalopathy syndrome

Isolated psoas schwannoma: A rare retroperitoneal tumor

Retroperitoneal neurogenic tumors are very rare. Isolated or primary psoas schwannoma is one of the rarest tumors of retroperitoneum. The images of such a case are presented in this report

Sella turcica size in women with sheehan syndrome—A case–control study

Introduction: Sheehan syndrome is a common cause of hypopituitarism in developing countries. Among risk factors, in addition to post-partum haemorrhage, a smaller sellar volume is also believed to predispose to pituitary necrosis. Some earlier studies have reported smaller sellar volume in these patients but involved a small number of patients and lacked matched controls. The main of the present study was to study the sellar volume in a large cohort of patients with Sheehan syndrome and compare it with age- and parity-matched controls. Methods: Fifty women with Sheehan syndrome and an equal number of age- and parity-matched controls were studied. Baseline investigations, relevant hormonal assay, and MRI of pituitary were studied in all. Results: Sellar volume was significantly lower in patients with Sheehan syndrome (334.50 ± 129.08 mm3 in patients as against 456.64 ± 169.25 mm3 in controls, P = 0.000). Far more women with Sheehan syndrome than controls had decreased sellar volume (40% vs. 12%). Conclusions: Patients with Sheehan syndrome have a smaller sellar volume that may be a non-modifiable risk factor for the development of post-partum pituitary necrosis

Diagnostic role of magnetic resonance hysterosalpingography in the evaluation of female infertility

Abstract Background In the evaluation of female infertility, hysterosalpingography (HSG) with fluoroscopy provides limited evaluation of congenital uterine malformation and extrauterine disease. Transvaginal ultrasonography (TVS) is though commonly used, has its limitations in assessment of tubes. Addition of sonosalpingography can help assess tubal patency but may be inconclusive in cases of unilateral or bilateral obstruction and is grossly operator dependent. Recent past has seen evolution of magnetic resonance imaging (MRI) to evaluate problems associated with female infertility, with unparalleled advantages of having no radiation and being less operator-dependent. The need to assess tubal patency has been addressed by increasing literature on utilization of gadolinium (Gd) in MRI and comparing it with HSG alone or a mixture of HSG and laparoscopy. We aimed to evaluate the sensitivity and specificity of using magnetic resonance imaging (MRI) and magnetic resonance hysterosalpingography (MRHSG) as a screening test for female infertility and to compare accuracy, positive predictive value and efficacy of MRI and MRHSG with laparoscopy. Results Fifty-four out of 63 patients had bilateral tubal patency (85.7%). Nine patients had tubal pathology (14.3%) out of which one had unilateral and eight had bilateral tubal obstruction. Endometrial cavity abnormality was found in four patients and ovarian abnormalities were detected in 28.5% patients. MRHSG has shown high sensitivity and specificity for tubal patency evaluation when compared to the true gold standard for tubal patency assessment, laparoscopic chromotubation. With laparoscopy as standard, there was 100% sensitivity and specificity for structural abnormality, myometrial abnormalities and endometrial cavity assessment in MRHSG. Conclusions In comparison with diagnostic laparoscopy, MRHSG was found to have good sensitivity and specificity for assessment of tubal patency, excellent sensitivity and specificity for the assessment of structural malformation and endometrial cavity lesions. Furthermore MRHSG was good in picking up extra-uterine diseases
